what we do
founded in 1987 by the current ceo andrew shepherd the omega 
business is focused on selling a wide range of specialist products 
primarily in the immunoassay in vitro diagnostics ivd market within 
three segments allergy and autoimmune food intolerance and 
infectious disease
we’re committed 
to addressing global 
health challenges
how we work
we identify major 
health challenges
we form partnerships 
to help find solutions 1 2
the company’s global reputation 
stems from its beginnings as a 
manufacturer of tests for a range of 
infectious diseases such as syphilis 
tuberculosis dengue fever chagas 
disease and malaria this reputation 
led to the opportunity to commercialise 
a groundbreaking cd4 technology
partnership with burnet institute in 
australia resulted in omega securing 
an exclusive global licence to a unique 
simple lateral flow pointofcare device 
confirming patient cd4 count is above or 
below 350 cells μl this has the opportunity 
to greatly reduce the number of patients 
lost to care as a result of the length of 
time between testing and treatment

2012 £1112 million our food intolerance 
division grew turnover by 13 with continued 
growth in genarrayt

 revenue with france 
becoming the largest market by sales 
food detective
®
 also performed well 
exceeding the £1m sales barrier for the 
ﬁrst time as reported at the halfyear 
stage the allergy and autoimmune division 
particularly in germany was affected by 
the weaker pollen season and euro exchange 
rate a part recovery in the second half meant 
that turnover reduced by 7 for the year 
infectious disease turnover was broadly 
unchanged showing a slight decline 
of 1 due mainly to a loss of revenue 
approximately £02 million following 
a ban of bloodbased tb tests by 
the indian government

gross proﬁt
gross proﬁt amounted to £705 million 
2012 £700 million and the gross margin 
was practically unchanged at 626 
compared to 630 in the previous year 
this level of gross proﬁt was in line with 
expectation as the food intolerance and 
allergyautoimmune divisions generate 
similar levels of gross proﬁt
adjusted proﬁt before taxation
the group generated an adjusted proﬁt 
before tax “adjusted pbt” of £078 million 
compared to £100 million in the previous 
year the reduction was mainly due to 
two reasons ﬁrstly the effect of increased 
costs associated with the direct subsidiary 
operation in india occurring at the same 
time as the loss of revenue from tb tests 
referred to above and secondly due to 
a reduced contribution from the omega 
gmbh allergy business in germany for 
the reasons referred to above there is 
a reconciliation between adjusted pbt 
and statutory pbt below the income 
statement on page 31
taxation 
the group continues to beneﬁt from 
an enhanced level of rd tax allowances 
due to the increase in capitalised development 
expenditure which qualiﬁes for the 
aforementioned tax allowances there is a 
tax credit of £031 million in the year compared 
to £005 million in the previous year
adjusted eps
given the tax credit situation above the group 
achieved an adjusted proﬁt after tax of £109 
million 2012 £105 million resulting in adjusted 
earnings per share of 13p 2012 12p 
balance sheet
assets
 intangible assets increased to £1035 million 
2012 £914 million reflecting the level of 
capitalised development expenditure offset by 
amortisation of intangible assets there have 
been no impairment charges against goodwill 
or intangible assets throughout the year
 inventory levels increased marginally to 
£183 million 2012 £169 million and reﬂect 
the additional need to carry inventory within 
our indian subsidiary
 cash at the yearend reduced to £0 16 million 
2012 £116 million reﬂecting the level of 
investment in development activity and loan 
repayments collectively exceeding cash 
generated from operating activities
liabilities
 trade and other payables increased 
to £168 million 2012 £145 million
 total borrowings and other ﬁnancial liabilities 
reduced to £135 million 2012 £143 million 
due mainly to repayment of loans of £05m 
and settlement of an idsisys licence fee 
instalment of £013 million offset by the 
creation in the year of the liability for the ﬁnal 
licence fee payment of £05 million due to ids
funding
during the ﬁnancial year the company 
negotiated an increase to its overdraft facility 
from £07 million to £17 million repayable 
on demand the facility was renewed at the 
beginning of may for one year prior to the 
institutional placing announced on 24 may 
2013 further to the approval of shareholders 
given at the general meeting on 10 june 
the group raised £4 million before expenses 
through the issue of 23529412 new ordinary 
shares at 17p per share the placing was 
oversubscribed and we are very grateful for 
the support of existing and new shareholders 
alike the additional funds will enable us 
to implement our main strategies below
product strategy
visitect
®
 cd4
feedback from the global hivaids 
healthcare community continues to underpin 
the signiﬁcance of the opportunity represented 
by the company’s pointofcare “poc” 
visitect
®
 cd4 test subject to a successful 
completion of the technology transfer from the 
burnet institute to the company a large part of 
the placing proceeds see funding above will 
be used both to scale up the manufacturing 
and inventorybuild of cd4 to meet the 
potential demand that undoubtedly exists 
for a poc product solution and to undertake 
incountry ﬁeld evaluations that are planned 
with major organisations active in the hivaids 
arena the early feasibility work undertaken 
to develop a smartphone app reader is also 
promising in scope and applicability in parts 
of the world where visitect
®
 cd4 is expected 
to have most impact this remains the most 
signiﬁcant nearterm opportunity for the group 
to achieve growth in shareholder value and is 
expected to lead to a longer term strategy for 
poc product opportunities in emerging and 
developing world infectious diseases
allergy automation
the group remains focused on launching 
a panel of approximately 40 allergy tests 
on the automated idsisys instrument 
by the end of march 2014 and the recently 
announced achievement of ﬁnalising the 
assay protocol on which all remaining 
development will take place along with 
the intention to appoint ids as distributor 
in their core markets of the uk germany 
france the nordic regions and the us 
means we remain committed to building 
a signiﬁcant presence in the growing 
automated allergy testing market
market strategy – bric focus
the ivd industry as a whole has seen a 
slowdown in growth during 2012 as the 
major european us and japanese markets 
have experienced increased pressure on 
reimbursement levels and cuts in national 
health expenditure by contrast the emerging 
markets particularly india and china have 
continued to experience doubledigit growth 
rates the group’s decision to set up its 
own subsidiary in india nearly two years ago 
appears prescient against this backdrop and 
is expected to achieve growth both with our 
existing food intolerance products and the 
recently launched allergodip
®
 doctor’s ofﬁce 
test both china and brazil are topﬁve 
markets ranked by sales of food detective
®
 
and the relationship with hob biotech in 
china is expected to deliver further growth 
in this market
board and employees
i am very pleased that we have been able 
to attract and appoint bill rhodes as a 
nonexecutive director to the board and 
look forward to working with him given 
his knowledge and experience built up 
over many years particularly with becton 
dickinson as we implement our strategies 
outlined above mike gurner has decided 
to retire and step down from the board 
with immediate effect i would like to thank 
mike for his contribution over the many years 
since the group became a public company 
and i on behalf of the board wish him all 
the best in his retirement
outlook
more than half of group turnover is generated 
in the uk and europe predominantly through 
the food intolerance and allergyautoimmune 
divisions the economic uncertainty in this 
region has led to a slowdown in growth in 
european ivd markets and the ability to grow 
our own business is not immune from the 
broader landscape in germany in particular 
the reimbursement picture remains uncertain 
and the early pollen season has once more 
suffered from some of the wettest weather 
seen in northern germany for many years 
sales in the middle east have also got off to 
a slower start in part linked to the political 
situation to counter risk in these areas we 
have a strategy to focus on the emerging bric 
markets and our success in growing revenue 
in the year ahead will be dependent on 
whether sales into these higher growth 
territories can compensate for the pressures 
being experienced in europe and elsewhere
beyond the immediate term our ability to 
drive growth will be best delivered through the 
successful commercialisation of the cd4 test 
and automated allergy tests on the idsisys 
instrument a signiﬁcant amount of progress 
has been made in the past year and it is now 
time to deliver on these strategies

strategy and kpis
omega aims to deliver organic growth from recently acquired 
products markets and technologies omega will also continue 
to pursue acquisition opportunities that are earnings enhancing 
or strategically placed in major growth markets
a robust strategy for 
tackling worldwide 
health issues
group strategy
acquisitions
global 
partnerships
signiﬁcant  
growth
the acquisition of the business and certain 
assets of the in vitro allergy diagnostics 
business of allergopharma joachim ganzer 
kg in december 2010 provided the group 
with access to the high value allergy 
testing market
in march 2011 the group entered into an 
exclusive patent licence agreement with 
a subsidiary of immunodiagnostic systems 
group plc ids enabling omega to develop 
a range of allergy immunoassays on 
ids’s automated system idsisys 
combined with omega’s experience in 
assay development this forms a strong 
platform for allergy testing
the global allergy market is currently 
estimated at 05 billion per year with 
a compound annual growth rate of 8 
the acquisition and partnership represent 
a signiﬁcant opportunity for revenue 
generation in this area

chief executive’s review
the group has seen a marginal increase 
in revenue for the year to £1126 million 
slightly ahead of last year’s ﬁgure 
2012 £1112 million 
it is pleasing to have managed to retain 
proﬁtability in turbulent economic times 
our decision to go direct in the indian 
market has been vindicated with a strong 
performance from the new team with 
visitect
® 
cd4 we have been making steady 
progress with the technology transfer process 
nearing completion and the latest results 
looking very encouraging in addition our 
allergy test development programme with 
the idsisys instrument has also made 
good progress
food intolerance
the food intolerance market has 
continued to grow despite the obvious 
pressures on consumer spending in 
europe and the segment has continued 
to perform very well with sales growing 
by 13 to £439 million for the year ended 
31 march 2013 2012 £390 million
sales of food detective
®
 grew by 
27 to £125 million 2012 £098 million 
with poland continuing to remain as the 
group’s largest market for this product 
the number of countries where we have 
now sold product has continued to increase 
to 72 2012 68 with an increase in volumes 
to 85214 kits 2012 60782 the top ﬁve 
markets account for just over 50 of sales 
with good growth in china and brazil which 
ﬁts with the group’s strategic focus on 
bric countries product registration in 
china ﬁnally concluded in december 2012 
and as a result we expect sales in china 
to increase the signing of an exclusive 
distribution agreement with super religare 
laboratories india’s largest independent 
laboratory chain should also lead to 
good sales growth going forward
sales of genarrayt

 reagents have 
increased by 18 to £184 million 2012 
£156 million with france overtaking spain

the progress with registration of food 
detective
®
 in the united states has 
continued to be slow and the fda has 
recently conﬁrmed that they will require 
either a 510k or pma application to be 
ﬁled the 510k route is considered to be 
the more unlikely option due to the lack of 
a suitable predicate device as such the 
timeline to registration remains uncertain 
the whole business area of food intolerance 
testing in the us is under review and other 
additional routes to market are being 
explored particularly for the genarrayt
®
 
laboratory testing system which we believe 
has good potential and could be subject to 
a less onerous regulatory environment
allergy and autoimmune
this segment has seen a reduction in sales 
of 7 to £416 million 2012 £448 million
sales for omega diagnostics gmbh 
‘omega gmbh’ our german subsidiary 
fell by 7 to £359 million 2012 £386 
million as reported at the interim results 
the ﬁrst half saw a weaker pollen season 
due to unseasonably wet weather a weaker 
euro also contributed to the lower result 
this segment performed better in the 
second half helped by the launch of an 
indian version of allergodip
®
 the company 
has also launched a new liquid format of 
the allergozyme
®
 product range which is 
expected to contribute to omega gmbh’s 
export performance in the new ﬁnancial year
sales of autoimmune tests reduced by 7 
to £057 million 2012 £062 million we 
previously reported that the current range 
of autoimmune test kits were limited to small 
labs with manual test systems continued 
consolidation in developed country laboratory 
markets mean that they require even more 
automation and menu driven solutions which 
has outpaced our own ability to invest in 
developing revised kit formats therefore 
the decision was taken to direct resources 
to the idsisys project however in india 
a market dominated by many small manual 
testing laboratories with less dependency 
on automated systems we have seen an 
increase in business and we expect to see 
further growth in the new ﬁnancial year
infectious diseaseother
sales of infectious disease products fell 
slightly by 1 to £271 million 2012 £275 
million this is despite the loss of annual 
sales of approximately £02 million in india 
due to a government ban on the import 
of bloodbased tb tests the market 
for the current range still remains highly 
competitive but we believe that the 
cd4 opportunity will be the step change 
in activity and focus required to transform 
this segment
cd4
the cd4 test branded as visitect
®
 cd4 was 
prelaunched at the 19th international aids 
conference aids 2012 in washington dc 
us on 2227 july 2012 and the response 
to the product was extremely encouraging 
with a high level of interest being shown by 
various governments nongovernmental 
organisations ngos and large multinational 
diagnostics companies from the responses 
received we believe that we are closest to 
bringing a cd4 pointofcare test to market 
amongst other groups working in this area 
this ﬁrst to market advantage will add extra 
impetus to the introduction of the commercial 
product when it becomes available
the project to transfer the technology from 
the burnet institute to omega is in its ﬁnal 
stages and despite it taking longer than we 
ﬁrst envisaged we are now in the process 
of selecting the ﬁnal highly scalable 
manufacturing protocol evaluation sites in 
hiv reference laboratories in the uk us 
and india are already established as well as 
a ﬁeld trial site in mozambique and other 
countries through various ngos
visitect
® 
cd4 was also showcased at the 
african society for laboratory medicine 
meeting in cape town south africa in 
december 2012 and the response to 
the product mirrored that in washington 
this meeting also gave us the opportunity 
to gain further intelligence as to the market 
potential for the product the global cd4 
need is expected to grow substantially over 
the next 8 years as countries scale up their 
hivaids treatment programmes the number 
of tests is expected to rise from current 2012 
levels of just over 30 million to nearly 60 million 
tests by 2020
the recent grant of a us patent for the cd4 
technology also underlines the strong ip 
position for the test which extends the 
current patent protection in south africa 
and the member states of the african 
intellectual property organisation with 
patents pending in many other territories
we have also been looking to enhance the

 cd4 product offering 
by responding to requests from key opinion 
leaders to provide a ‘connectivity solution’ so 
that results can be transmitted from rural test 
sites to citybased ministry locations although 
the test does not need an instrument to read 
the result we have recently completed a 
feasibility study in using a smartphone camera 
to capture the result and then to transmit the 
result to management centres while removing 
any operator subjectivity in interpreting the 
results it could also provide additional beneﬁts 
such as disease demographic studies and 
supply chain logistics a common problem 
found in resourcepoor countries
distribution network 
sales growth has been recorded in most 
geographic regions of the world with the 
exception of europe which reduced by 1 
to £641 million 2012 £648 million and the 
africamiddle east region which dropped 
by 4 to £156 million 2012 £163 million 
these reductions were more than offset by 
good growth in the asiafar east markets 
with sales rising by 9 to £144 million 
2012 £132 million and in the north 
american market by sales rising 6 to 
£035 million 2012 £033 million sales 
to southcentral america rose by 16 
to £051 million 2012 £044 million
bric strategy
in the year we have further concentrated 
our efforts on expanding our business in 
the bric group of countries and we have 
met with some success in brazil we 
increased sales by 10 to £029 million 
2012 £026 million in china we increased 
sales by 49 to £018 million 2012 £012 
million but in russia sales decreased by 
31 to £010 million 2012 £015 million 
which was due to the timing of contract 
deliveries and the introduction of 
competitive automated systems
direct sales in india commenced at the end 
of july last year and the team has achieved 
an impressive sales performance which 
when aggregated with the ﬁnal sales made 
by the old distributor in the three months of 
apriljune 2012 meant total indian sales 
of approximately £040m for the year this 
compares to a prior year likeforlike sales 
ﬁgure of approximately £020 million which 
excludes the tb product sales noted earlier
discussions have also been taking place 
with other ivd companies with a view to 
representing them in the indian market 
and two distribution agreements have 
already been signed with others in 
early stage discussions  12

research and development
idsisys
during the year our development efforts 
have focussed on a core set of assays with 
the ﬁrst group of 10 allergens completing 
optimisation however during that process 
certain imprecision issues were identiﬁed 
with the assay protocol which whilst taking 
longer to resolve than ﬁrst anticipated have 
now been resolved this protocol will now 
be used throughout the remaining 
development programme and the claim 
support phase with the ﬁrst 10 allergens 
has now commenced the previous 
problem with the sourcing of sufﬁcient 
patient serum samples has now been 
resolved with enough material in stock 
to undertake the optimisation and claim 
support work for a further 30 allergens 
therefore with the reproducibility of the 
chosen protocol overall we now anticipate 
launching a panel of 40 allergens by the 
end of march 2014
in our last annual report we commented 
on efforts to either source or develop a 
multiplex testing platform for allergen 
speciﬁc ige testing whilst those initial tests 
were encouraging no further efforts have 
been made on this project as we decided 
to concentrate our development resources 
on the isys programme

outlook
the new ﬁnancial year presents some 
challenges for the management team 
in terms of market and overall economic 
conditions with new product introductions 
into key markets such as india and further 
growth in food intolerance in china and 
brazil we expect to be able to respond 
positively to these challenges the ‘game

cd4 product is expected to make a major 
impact in global health markets as this 
test satisﬁes a current unmet clinical need
over the last year we have been given 
deep insight into the ngoaidrelated business 
sector which is where the visitect
®
 cd4 test 
is targeted until now this sector has not been 
at the forefront of our commercial focus but 
we are reviewing this part of our strategy with 
a view to identifying other opportunities that 
would ﬁt into this sector one such opportunity 
that may exist is in the area of hiv viral load 
testing an area which is highly complementary 
to cd4 testing
we have been delighted at the support 
received from existing shareholders and 
new investors for our recent oversubscribed 
fundraising and while there are challenges 
in the eurozone countries we believe our 
continued focus on new products such as 
cd4 and the bric markets should result 
in further proﬁtable growth

cd4 could transform the way that care and treatment are provided 
to hivpositive patients particularly in developing countries
infectious diseases 
a change in activity 
and market focus
turnover in the infectious disease division 
was effectively ﬂat with sales of £271 million 
compared to £275 million in the prior year 
this result is despite the loss of tb sales in 
india due to a government ban on the import 
of all bloodbased tb tests and which in 
the prior year accounted for approximately 
£02 million of the company’s revenue 
the market for the current range still remains 
highly competitive but we believe that the 
cd4 opportunity will be the step change 
in activity and focus required to transform 
this segment the increased level of 
administration costs incurred through the 
indian subsidiary has resulted in adjusted 
pbt falling to £017 million from £032 million 
the year before
the cd4 test branded as visitect
®
 cd4 was 
prelaunched at the 19th international aids 
conference aids 2012 in washington dc 
us on 22–27 july 2012 and the response 
to the product was extremely encouraging 
with a high level of interest being shown by 
various governments nongovernmental 
organisations ngos and large multinational 
diagnostics companies from the responses 
received we believe that we are closest to 
bringing a cd4 pointofcare test to market 
amongst other groups working in this area 
the project to transfer the technology 
from the burnet institute to omega is in 
its ﬁnal stages and despite it taking longer 
than we ﬁrst envisaged we are now in the 
process of selecting the ﬁnal highly scalable 
manufacturing protocol evaluation sites 
in hiv reference laboratories in the uk 
us and india are already established as well 
as a ﬁeld trial site in mozambique and other 
countries through various ngos
visitect

cd4 was also showcased at the 
african society for laboratory medicine 
meeting in cape town south africa in 
december 2012 and the response to 
the product mirrored the experience of 
washington this meeting also gave us 
the opportunity to gain further intelligence 
as to the market potential for the product 
the global cd4 need is expected to grow 
substantially over the next eight years as 
countries scale up their hivaids treatment 
programmes with the number of tests 
rising from current 2012 levels of just over 
30 million to nearly 60 million tests by 2020
the recent grant of a us patent for the 
cd4 technology also underlines the strong 
intellectual property position for the test 
which extends the current patent protection 
in south africa and the member states of 
the african intellectual property organisation 
with patents pending in many other territories

currency management
the group continues to transact operations 
in three main currencies being sterling euros 
and us dollars in the case of transactions 
in euros and us dollars the group may 
be exposed to ﬂuctuations in the rates of 
exchange against sterling where possible 
the group operates a natural hedge by 
entering into transactions of both a buying 
and selling nature that limits the risk of 
adverse exchange rate losses the company 
generates a net surplus of us dollars from 
its trading activities the exchange rate 
between sterling and the us dollar has 
been relatively stable throughout the year 
such that a translation loss of £1k 2012 
£1k was recorded on us dollar borrowings 
held throughout the ﬁrst half of the year 
but now repaid in full along with a loss 
on trading operations of £2k 2012 £22k 
included within administration costs
the group’s net investment in and funding 
of omega gmbh is in euros which will give 
rise to foreign exchange variations from 
one period to another in the year a foreign 
exchange gain of £27k 2012 loss of £271k 
which has arisen due to a stronger euro 
as measured at yearend rates has been 
included within other comprehensive income
interest rate management
during the ﬁrst half of the year the group 
operated certain derivative ﬁnancial 
instruments for its sterling and us dollar 
borrowings in the case of its sterling loan 
the group operated an instrument to cap 
interest at 55 and in the case of the us 
dollar loan the group operated instruments 
to cap the interest rate based on us libor at 
5 and one to operate a ﬂoor rate on us 
libor of 225 these instruments terminated 
on repayment of the associated borrowings 
during the year there was a fair value 
adjustment gain through the income

net cash ﬂow generated from operations 
improved signiﬁcantly to £101 million 2012

principal risks and uncertainties
the board meets regularly to review operations and to discuss risk areas the corporate governance report contains details 
of the group’s system of internal control note 22 to the ﬁnancial statements contains details of ﬁnancial risks faced by the group
the board considers the following to be the nonﬁnancial risks
general economic conditions
the group may be faced with changes in the general economic climate in each territory in which it operates that may adversely affect the 
ﬁnancial performance of the group factors which may contribute include the level of direct and indirect competition against the group 
industrial disruption rate of growth of the group’s sectors and interest rates the group seeks to mitigate this risk by conducting 
operations on a broad geographic basis and by introducing new technologies to remain innovative
regulatory risk
the manufacturing marketing and use of the group’s products are subject to regulation by government and regulatory agencies in many 
countries of particular importance is the requirement to obtain and maintain approval for a product from the applicable regulatory agencies 
to enable the group’s products to be marketed approvals can require clinical evaluation of data relating to safety quality and efﬁcacy 
of a product the group seeks to mitigate regulatory risk by conducting its operations within recognised quality assurance systems and 
undergoes external assessment to ensure compliance with these systems
acquisition risk
the success of the group depends upon the ability of the directors to assimilate and integrate the operations personnel technologies 
and products of acquired companies the group seeks to mitigate this risk by selecting companies that meet certain selection criteria 
and by conducting a detailed due diligence review
eurozone risk
recent turmoil in the economic conditions in europe increases the risk of one or more countries exiting the eurozone this could lead to 
currency devaluation in those countries which could lead to adverse economic impacts elsewhere approximately one third of the group’s 
revenue is derived in germany where the euro is the functional reporting currency the group does not currently have operations located 
in any other european country however in the event of a country’s exit from the eurozone potentially higher volatility of the euro could 
lead to a reduction in the reported trading results of our german operation when translated into sterling the group mitigates risk in 
countries such as spain and italy where it has trading relationships with tighter credit control procedures and credit limits where 
necessary
development risk
the group is undertaking an increased level of development activity than in the past with the aim of launching new products in the future 
there is no guarantee that development activity will lead to the future launch of products such development activity can meet technical 
hurdles that are unable to be overcome and market and competition activity can render the output from development activities as obsolete 
the group seeks to mitigate the risk around development activities by ensuring that development programmes are planned in accordance 
with recognised industry quality standards managed by people with the requisite skills the company also continues to monitor industry 
trends and customer needs to ensure its development targets remain relevant
donations
the group made no charitable donations in the year 2012 £nil nor any political donations 2012 £nil
auditors
the auditors ernst  young llp have indicated their willingness to continue in ofﬁce and a resolution for their reappointment will 
be proposed at the forthcoming annual general meeting
directors’ statement as to disclosure of information to auditors
the directors who were members of the board at the time of approving the directors’ report are listed on page 23 having made 
enquiries of fellow directors and of the company’s auditors each of these directors conﬁrms that
 − to the best of each director’s knowledge and belief there is no information that is information needed by the group’s auditors

statements these ﬁnancial statements are presented in sterling and have been prepared in accordance with ifrs as adopted by the eu 
and applied in accordance with the provisions of the companies act 2006
in relation to ifrs 8 – operating segments the group has identiﬁed the executive board as the chief operating decision maker with 
responsibility for decisions over the allocation of resources to operating segments and for the monitoring of their performance the group 
reports performance of the following three segments
 − allergy and autoimmune
 − food intolerance

basis of consolidation
the group ﬁnancial statements consolidate the ﬁnancial statements of omega diagnostics group plc and the entities it controls 
its subsidiaries control comprises the power to govern the ﬁnancial and operating policies of the investee so as to obtain beneﬁt from its 
activities and is achieved through direct or indirect ownership of voting rights subsidiaries are consolidated from the date of acquisition 
being the date on which the group obtains control and continue to be consolidated until the date that such control ceases the ﬁnancial 
statements of the subsidiaries used in the preparation of the consolidated ﬁnancial statements are based on consistent accounting 
policies all intercompany balances and transactions including unrealised proﬁts arising from them are eliminated
intangible assets
goodwill
business combinations are accounted for under ifrs 3 using the acquisition method goodwill represents the excess of the cost of the 
business combination over the group’s interest in the net fair value of the identiﬁable assets liabilities and contingent liabilities goodwill is 
not amortised but is subject to an annual impairment review and whenever events or changes in circumstances indicate that the carrying 
value may be impaired a charge is made to the income statement after initial recognition goodwill is stated at cost less any accumulated 
impairment losses
for the purpose of impairment testing goodwill is allocated to the related cashgenerating units monitored by management usually 
at business segment level or statutory company level as the case may be where the recoverable amount of the cashgenerating unit 
is less than its carrying amount including goodwill an impairment loss is recognised in the income statement
other intangible assets
intangible assets acquired as part of a business combination are recognised outside goodwill if the asset is separable or arises from contractual 
or other legal rights and its fair value can be measured reliably following initial recognition at fair value at the acquisition date the historic 
cost model is applied with intangible assets being carried at cost less accumulated amortisation and accumulated impairment losses 
intangible assets with a ﬁnite life have no residual value and are amortised on a straight line basis over the expected useful lives with 
charges included in administration costs as follows
technology assets – 5–20 years
customer relationships – 5–10 years
supply agreements – 5 years
other intangibles – 5 years
software – 5 years
the carrying value of intangible assets is reviewed for impairment whenever events or changes in circumstances indicate the carrying 
value may not be recoverable
research and development costs
expenditure on research and initial feasibility work is written off through the income statement as incurred thereafter expenditure on 
product development which meets certain criteria is capitalised and amortised over its useful life the stage at when it is probable that the 
product will generate future economic beneﬁts is when the following criteria have been met technical feasibility intention and ability to sell 
the product availability of resources to complete the development of the product and the ability to measure the expenditure attributable 
to the product the useful life of the intangible asset is determined on a productbyproduct basis taking into consideration a number 
of factors development costs previously recognised as an expense are not recognised as an asset in a subsequent period

overview business review governance financial statements
omega diagnostics group plc annual report and group financial statements 2013
2 accounting policies continued
property plant and equipment
property plant and equipment are stated at cost less accumulated depreciation and any accumulated impairment losses depreciation is 
charged so as to write off the cost of assets to their estimated residual values over their estimated useful lives on a straight line basis as follows
land and property – 33 years straight line with no residual value
leasehold improvements – 10 years straight line with no residual value
plant and machinery – 8 to 10 years straight line with no residual value
motor vehicles – 5 years straight line with no residual value
the carrying values of property plant and equipment are reviewed for impairment if events or changes in circumstances indicate the 
carrying value may not be recoverable and are written down immediately to their recoverable amount useful lives are reviewed annually 
and where adjustments are required these are made prospectively
impairment of assets
the group and company assess at each reporting date whether there is an indication that an asset may be impaired if any such indication 
exists the group and company makes an estimate of the asset’s recoverable amount an asset’s recoverable amount is the higher of an 
asset’s or cashgenerating unit’s fair value less costs to sell and its value in use and is determined for an individual asset unless the asset 
does not generate cash inﬂows that are largely independent of those from other assets or groups of assets where the carrying amount 
of an asset exceeds its recoverable amount the asset is considered to be impaired and is written down to its recoverable amount 
in assessing value in use the estimated future cash ﬂows are discounted to their net present value using a pretax discount rate that 
reﬂects current market assessments of the time value of money and the risks speciﬁc to that asset impairment losses on continuing 
operations are recognised in the income statement in those expense categories consistent with the function of the impaired asset
inventories
inventories are stated at the lower of cost and net realisable value cost is deﬁned as standard cost or purchase price and includes all 
direct costs incurred in bringing each product to its present location and condition net realisable value is based on estimated selling 
price less any further costs expected to be incurred prior to completion and disposal 
trade receivables
trade receivables are recognised initially at fair value and subsequently measured at the lower of original invoice amount and recoverable 
amount a provision for doubtful amounts is made when there is objective evidence that collection of the full amount is no longer probable 
signiﬁcant ﬁnancial difﬁculty or signiﬁcantly extended settlement periods are considered to be indicators of impairment normal average 
payment terms vary from payment in advance to 90 days balances are written off when the probability of recovery is assessed as remote 
cash and cash equivalents
cash and cash equivalents in the balance sheet comprise cash at banks and in hand and shortterm deposits with an original maturity 
of three months or less
financial instruments

financial assets are classiﬁed as either
 − ﬁnancial assets at fair value through proﬁt or loss or

financial assets at fair value through proﬁt or loss
the group uses derivative ﬁnancial instruments to reduce its exposure to ﬂuctuations in interest rates both in sterling and us dollars 
the group does not hold or issue derivatives for speculative or trading purposes derivative ﬁnancial instruments with positive fair values 
are recognised as assets measured at their fair values at the balance sheet date the fair value of interest rate contracts is determined 
by reference to market values for similar instruments that have similar maturities changes in fair value are recognised in the income 
statement included in ﬁnance costs due to the fact that hedge accounting has not been applied
loans and receivables
trade receivables that do not carry any interest and have ﬁxed or determinable payment amounts that are not quoted in an active market 
are classiﬁed as loans and receivables loans and receivables with a maturity of less than twelve months are included in current assets and 
are measured at amortised cost using the effective interest method as reduced by appropriate allowances for estimated irrecoverable amounts 
financial liabilities are classiﬁed as either
 − ﬁnancial liabilities at fair value through proﬁt or loss or
 − other liabilities 40

the group uses derivative ﬁnancial instruments to reduce its exposure to ﬂuctuations in interest rates both in sterling and us dollars 
the group does not hold or issue derivatives for speculative or trading purposes derivative ﬁnancial instruments with negative fair values 
are recognised as liabilities measured at their fair values at the balance sheet date the fair value of interest rate contracts is determined

statement included in ﬁnance costs due to the fact that hedge accounting has not been applied
other ﬁnancial liabilities whether used as part of the consideration for acquisitions which include deferred consideration or not are designated 
by the group as ﬁnancial liabilities at fair value through proﬁt and loss they are measured at the present value of the consideration expected 
to be payable by discounting the expected future cash ﬂows at prevailing interest rates at initial recognition the quantum of liability to be 
recognised will depend upon management’s expectation at that date of the amount that would ultimately be payable where there is 
a change in the expectation of future cash ﬂows or interest rates the change is reﬂected through the income statement
other liabilities
trade payables are not interest bearing and are recognised initially at fair value and subsequently measured at amortised cost using 
the effective interest method
bank borrowings are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method 
for longterm bank borrowings stated at amortised cost transaction costs that are directly attributable to the borrowing instrument are 
recognised as an interest expense over the life of the instrument
a ﬁnancial asset or liability is generally derecognised when the contract that gives rise to it is settled sold cancelled or expires where an 
existing ﬁnancial liability is replaced by another from the same lender on substantially different terms or the terms of an existing liability 
are substantially modiﬁed such an exchange or modiﬁcation is treated as a derecognition of the original liability and recognition of the 
new liability such that the difference in the respective carrying amounts together with any costs or fees incurred are recognised
financial assets and liabilities that are held for trading and other assets and liabilities designated as such on inception are included at fair 
value through proﬁt and loss financial assets and liabilities are classiﬁed as held for trading if they are acquired for sale in the short term 
derivatives are also classiﬁed as held for trading unless they are designated as hedge instruments assets are carried in the balance sheet 
at fair value with gains or losses recognised in the income statement

gains and losses arising on retranslation are included in the net proﬁt or loss for the year the trading results of the overseas subsidiaries 
are translated at the average exchange rate ruling during the year with the exchange difference between the average rates and the rates 
ruling at the balance sheet date being taken to reserves any difference arising on the translation of the opening net investment in the 
overseas subsidiaries and of applicable foreign currency loans are dealt with as adjustments to reserves 
revenue recognition
revenue is measured at the fair value of the consideration received or receivable and net of discounts and salesrelated taxes sales of 
goods are recognised when the signiﬁcant risks and rewards of ownership are transferred to the customer this will be when goods have 
been dispatched and the collection of the related receivable is reasonably assured revenue relates to the sale of medical diagnostic kits
government grants
government grants are recognised when it is reasonable to expect that the grants will be received and that all related conditions will be met 
usually on submission of a valid claim for payment government grants in respect of capital expenditure are credited to a deferred income 
account and are released to the income statement over the expected useful lives of the relevant assets by equal annual instalments
leasing and hire purchase commitments
assets held under ﬁnance leases and hire purchase contracts are capitalised in the balance sheet and are depreciated over the shorter 
of their lease period and useful life the corresponding lease or hire purchase obligation is capitalised in the balance sheet as a liability 
the interest element of the rental obligation is charged to the income statement over the period of the lease and represents a constant 
proportion of the balance of capital repayments outstanding
rentals applicable to operating leases where substantially all the beneﬁts and risks remain with the lessor are charged against proﬁts 
on a straight line basis over the period of the lease

equitysettled transactions
for equitysettled transactions the group measures the award by reference to the fair value at the date at which they are granted and it is 
recognised as an expense over the vesting period which ends on the date on which the relevant employees become fully entitled to the award 
fair value is determined using an appropriate pricing model in valuing equitysettled transactions no account is taken of any service and 
performance vesting conditions other than conditions linked to the price of the shares of the company market conditions 
any other conditions which are required to be met in order for an employee to become fully entitled to an award are considered to be 
nonvesting conditions like market performance conditions nonvesting conditions are taken into account in determining grant date fair 
value no expense is recognised for awards that do not ultimately vest except for awards where vesting is conditional upon a market or 
nonvesting condition which are treated as vesting irrespective of whether or not the market or nonvesting condition is satisﬁed provided 
that all other performance conditions are satisﬁed
at each balance sheet date before vesting the cumulative expense is calculated representing the extent to which the vesting period has 
expired and management’s best estimate of the achievement or otherwise of vesting conditions and of the number of equity instruments 
that will ultimately vest or in the case of an instrument subject to a market or nonvesting condition be treated as vesting as described above 
this includes any award where nonvesting conditions within the control of the group or the employee are not met the movement in 
cumulative expense since the previous balance sheet date is recognised in the income statement with a corresponding entry in equity
where the terms of an equitysettled award are modiﬁed or a new award is designated as replacing a cancelled or settled award the cost 
based on the original award terms continues to be recognised over the original vesting period in addition an expense is recognised over 
the remainder of the new vesting period for the incremental fair value of any modiﬁcation based on the difference between the fair value 
of the original award and the fair value of the modiﬁed award both as measured on the date of the modiﬁcation no reduction is 
recognised if this difference is negative
where an equitysettled award is cancelled it is treated as if it had vested on the date of cancellation and any cost not yet recognised in 
the income statement for the award is expensed immediately any compensation paid up to the fair value of the award at the cancellation 
or settlement date is deducted from equity with any excess over fair value being treated as an expense in the income statement
pension contributions
contributions to personal pension plans of employees on a deﬁned contribution basis are charged to the income statement in the year 
in which they are payable
the group also operates two deﬁned beneﬁt plans in germany which are closed to new members obligations under deﬁned beneﬁt 
plans are measured at discounted present values by actuaries while plan assets are recorded at fair value the operating and ﬁnancing 
costs of pensions are charged to the income statement in the period in which they arise and are recognised separately the difference 
between actual and expected returns on assets during the year including changes in actuarial assumptions are recognised in the 
statement of comprehensive income
income taxes
current tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities based 
on tax rates and laws that are enacted or substantively enacted by the balance sheet date
deferred income tax is recognised on all temporary differences arising between the tax bases of assets and liabilities and their carrying 
amounts in the ﬁnancial statements with the following exceptions
 − where the temporary difference arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business 
combination that at the time of the transaction affects neither accounting nor taxable proﬁt or loss
 − in respect of taxable temporary differences associated with investments in subsidiaries associates and joint ventures where the timing 
of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the 
foreseeable future and
 − deferred income tax assets are recognised only to the extent that it is probable that taxable proﬁt will be available against which 
the deductible temporary differences carried forward tax credits or tax losses can be utilised
deferred income tax assets and liabilities are measured on an undiscounted basis at the tax rates that are expected to apply when the 
related asset is realised or the liability is settled based on tax rates and laws enacted or substantively enacted at the balance sheet date
income tax and deferred tax is charged or credited in other comprehensive income or directly to equity if it relates to items that are credited 
or charged in other comprehensive income or directly to equity otherwise income tax and deferred tax is recognised in proﬁt or loss
use of estimates and judgements
the preparation of these ﬁnancial statements requires management to make judgements estimates and assumptions that affect 
the application of accounting policies and the reported amounts of assets liabilities income and expenses actual results may differ 
from these estimates
estimates and underlying assumptions are reviewed on an ongoing basis revisions to accounting estimates are recognised in the period 
in which the estimate is revised and in any future periods affected
the signiﬁcant areas of estimation and uncertainty and critical judgements in applying the accounting policies that have the most 
signiﬁcant effect on the amounts recognised in the ﬁnancial information are discussed overleaf further judgements assumptions 
and estimates are set out in the group ﬁnancial statements 42

use of estimates and judgements continued
valuation of intangible assets
management judgement is required to estimate the useful lives of intangible assets having reference to future economic beneﬁts 
expected to be derived from use of the asset economic beneﬁts are based on the fair values of estimated future cash ﬂows
impairment of goodwill
goodwill is tested annually for impairment the test considers future cash ﬂow projections of cashgenerating units that give rise to the 
goodwill where the discounted cash ﬂows are less than the carrying value of goodwill an impairment charge is recognised for the difference 
further analysis of the estimates and judgements is disclosed in note 8
deferred tax assets
management judgement is required to determine the amount of deferred tax assets that can be recognised based upon the likely timing 
and level of future taxable proﬁts together with an assessment of the effect of future tax planning strategies the carrying value of the 
deferred tax asset at 31 march 2013 is £553647 2012 £150332 further details are contained in note 14

in his budget speech on 20 march 2013 the chancellor announced that the main uk corporation tax rate would be reduced from 
the current rate of 24 to 20 by 2015 the rate of corporation tax reduced from 28 to 26 on 1 april 2011 and a reduction to 24 
effective from 1 april 2012 was included in the finance bill that was enacted on 17 july 2012 a further reduction in the corporation 
tax rate to 23 effective from 1 april 2013 was also included in the finance bill
as the reduction in the rate to 23 was enacted at the balance sheet date this is the rate at which deferred tax has been provided 
the further rate reductions are to be incorporated within future legislative acts and so will not be substantively enacted until later 
periods the estimated impact of the proposed further rate reduction to 20 would be to reduce the deferred tax liability by £7272 46

the expected life of the options is based on management’s assumption of the options’ life due to the lack of any historical data on the 
exercise period of these options the assumption takes into account the experience of employees and directors and is not necessarily 
indicative of exercise patterns that may occur
the expected volatility reﬂects the assumption that historical volatility over a period similar to the life of the option is indicative of future trends 
which may not necessarily be the actual outcome

impairment testing of goodwill
the group tests goodwill annually for impairment or more frequently if there are indicators of impairment the carrying amount of goodwill 
is indicated in the table above the net book value of goodwill above for genesiscns amounts to £3016892 2012 £3016892 cotek 
£332986 2012 £332986 and omega gmbh £1334900 2012 £1323063
the recoverable amount of genesiscns cotek and omega gmbh has been determined based on a value in use calculation using 
cash ﬂow projections based on the actual results for the year ended 31 march 2013 and the ﬁnancial budget approved by the board covering 
the period to 31 march 2014 with projected cash ﬂows thereafter through to march 2017 based on a growth rate of 3 per annum the key 
assumptions used in the budget for genesiscns are the sales projections which are predicated on the continued success of the genarrayt
®
 
and food detective
®
 assays being commercialised on an international basis and the gross margins which can be achieved from the sales of 
these products the key assumption used in the budget for cotek is the growth in sales of the company’s micropath™ range of products 
where increased volumes are dependent upon having accessed a lower manufacturing cost through the acquisition of cotek itself the 
budget for omega gmbh assumes continued organic growth in sales in the german market as well as achieving an increase in export sales 
through the existing omega international distribution network the omega gmbh forecast also includes revenues in years two to ﬁve from 
the idsisys platform which will allow more rapid processing of higher volume tests
in all three cases the company also makes assumptions in regard to having sufﬁcient production personnel to cope with increased volumes 
the discount rate applied to cash ﬂows is 125 for the group which takes account of other risks speciﬁc to each segment such as currency 
risk geography and price risk the discount rate is the weighted average cost of pretax cost of debt ﬁnancing and the pretax cost of 
equity ﬁnancing cash ﬂows beyond the budget period are extrapolated for genesiscns cotek and omega gmbh over the next four 
years using a growth rate of 3 that equates to the current growth rate in the ivd industry thereafter a nil growth rate has been assumed 
for prudence as a result there has been no impairment to the carrying value of goodwill
sensitivity analysis
base forecasts show headroom of £47 million above carrying value for genesiscns headroom of £410000 above carrying value for 
cotek and headroom of £800000 for omega gmbh sensitivity analysis has been undertaken to assess the impact of any reasonably 
possible change in key assumptions if the growth rate were to drop from 3 to 1 this would have the effect of reducing the headroom 
in genesiscns by £191000 over ﬁve years in cotek by £29000 over ﬁve years and in omega gmbh by £45000 over ﬁve years
for genesiscns the discount rate would have to increase to 48 or the growth rate would have to be a decline of 81 for the headroom 
to reduce to £nil
for cotek the discount rate would have to increase to 55 or the growth rate would have to be a decline of 37 for the headroom 
to reduce to £nil
for omega gmbh the discount rate would have to increase to 22 or the growth rate would have to be a decline of 44 for the headroom 
to reduce to £nil

be no impact on the net deﬁned beneﬁt liability the net charge to next year’s income statement will increase by approximately £6300

beneﬁt obligation and the expected return on plan assets recognised under the current standard this increase in the net charge to next

within other loans designated at fair value through proﬁt and loss is the vendor loan note of £11 million which was issued in september 2007  
it carries a coupon of base rate only and is repayable in three equal instalments of £360000 in september 2012 2013 and 2014 and a ﬁnal 
capital payment of £20k in september 2015 the interest is rolled up and repayable with the ﬁnal capital payment the fair value is calculated 
as the future cash ﬂows expected to result based on current estimates of interest rates there has been no change in the year to the fair value 
of the loan due to changes in credit risk the movement in the year of £338781 2012 £28154 is due to the ﬁrst instalment being paid 
in september 2012 £360000 offset by the effect of unwinding discount factors £21219 which is included within ﬁnance charges 
in the income statement
financial risk management
the principal ﬁnancial risks to which the group is exposed are those relating to foreign currency credit liquidity and interest rate 
these risks are managed in accordance with boardapproved policies
foreign currency risk
the group operates in more than one currency jurisdiction and is therefore exposed to currency risk on the retranslation of the income 
statement and the balance sheet of its overseas subsidiaries from euros and rupees into its functional currency of pounds sterling 
the company funds its subsidiaries by a mixture of equity and intercompany loan ﬁnancing and these balances are subject to exchange 
rate movements that can give rise to movements in equity the group also buys and sells goods and services in currencies other than the 
functional currency principally in euros and us dollars the group has us dollar and eurodenominated bank accounts and where possible 
the group will offset currency exposure where purchases and sales of goods and services can be made in these currencies the group’s 
nonsterling revenues proﬁts assets liabilities and cash ﬂows can be affected by movements in exchange rates it is currently group policy 
not to engage in any speculative transaction of any kind but this will be monitored by the board to determine whether it is appropriate 
to use additional currency management procedures to manage risk at 31 march 2013 and 31 march 2012 the group has not entered 
into any hedge transactions
the following table demonstrates the sensitivity to a possible change in currency rates on the group’s proﬁt before tax and equity through

impact on the company’s proﬁt before tax and equity
credit risk
the group’s credit risk is primarily attributable to its trade receivables the group conducts its operations in many countries so there is 
no concentration of risk in any one area in most cases the group grants credit without security to its customers creditworthiness checks 
are undertaken before entering into contracts with new customers and credit limits are set as appropriate the group conducts most of 
its operations through distributors and is therefore able to maintain a fairly close relationship with its immediate customers as such the 
group monitors payment proﬁles of customers on a regular basis and is able to spot deteriorations in payment times an allowance for 
impairment is made that represents the potential loss in respect of individual receivables where there is an identiﬁable loss event which 
based on previous experience is evidence of a reduction in the recoverability of cash ﬂows the amounts presented in the balance sheet 
are net of allowance for doubtful receivables an analysis of trade receivables from various regions is analysed in the following table

overview business review governance financial statements
gross proﬁt
gross proﬁt amounted to £705 million 
2012 £700 million and the gross margin 
was practically unchanged at 626 
compared to 630 in the previous year 
this level of gross proﬁt was in line with 
expectation as the food intolerance and 
allergyautoimmune divisions generate 
similar levels of gross proﬁt
adjusted proﬁt before taxation
the group generated an adjusted proﬁt 
before tax “adjusted pbt” of £078 million 
compared to £100 million in the previous 
year the reduction was mainly due to 
two reasons ﬁrstly the effect of increased 
costs associated with the direct subsidiary 
operation in india occurring at the same 
time as the loss of revenue from tb tests 
referred to above and secondly due to 
a reduced contribution from the omega 
gmbh allergy business in germany for 
the reasons referred to above there is 
a reconciliation between adjusted pbt 
and statutory pbt below the income 
statement on page 31
taxation 
the group continues to beneﬁt from 
an enhanced level of rd tax allowances 
due to the increase in capitalised development 
expenditure which qualiﬁes for the 
aforementioned tax allowances there is a 
tax credit of £031 million in the year compared 
to £005 million in the previous year
adjusted eps
given the tax credit situation above the group 
achieved an adjusted proﬁt after tax of £109 
million 2012 £105 million resulting in adjusted 
earnings per share of 13p 2012 12p 
balance sheet
assets
 intangible assets increased to £1035 million 
2012 £914 million reflecting the level of 
capitalised development expenditure offset by 
amortisation of intangible assets there have 
been no impairment charges against goodwill 
or intangible assets throughout the year
 inventory levels increased marginally to 
£183 million 2012 £169 million and reﬂect 
the additional need to carry inventory within 
our indian subsidiary
 cash at the yearend reduced to £0 16 million 
2012 £116 million reﬂecting the level of 
investment in development activity and loan 
repayments collectively exceeding cash 
generated from operating activities
liabilities
 trade and other payables increased 
to £168 million 2012 £145 million
 total borrowings and other ﬁnancial liabilities 
reduced to £135 million 2012 £143 million 
due mainly to repayment of loans of £05m 
and settlement of an idsisys licence fee 
instalment of £013 million offset by the 
creation in the year of the liability for the ﬁnal 
licence fee payment of £05 million due to ids
funding
during the ﬁnancial year the company 
negotiated an increase to its overdraft facility 
from £07 million to £17 million repayable 
on demand the facility was renewed at the 
beginning of may for one year prior to the 
institutional placing announced on 24 may 
2013 further to the approval of shareholders 
given at the general meeting on 10 june 
the group raised £4 million before expenses 
through the issue of 23529412 new ordinary 
shares at 17p per share the placing was 
oversubscribed and we are very grateful for 
the support of existing and new shareholders 
alike the additional funds will enable us 
to implement our main strategies below
product strategy
visitect
®
 cd4
feedback from the global hivaids 
healthcare community continues to underpin 
the signiﬁcance of the opportunity represented 
by the company’s pointofcare “poc” 
visitect
®
 cd4 test subject to a successful 
completion of the technology transfer from the 
burnet institute to the company a large part of 
the placing proceeds see funding above will 
be used both to scale up the manufacturing 
and inventorybuild of cd4 to meet the 
potential demand that undoubtedly exists 
for a poc product solution and to undertake 
incountry ﬁeld evaluations that are planned 
with major organisations active in the hivaids 
arena the early feasibility work undertaken 
to develop a smartphone app reader is also 
promising in scope and applicability in parts 
of the world where visitect
®
 cd4 is expected 
to have most impact this remains the most 
signiﬁcant nearterm opportunity for the group 
to achieve growth in shareholder value and is 
expected to lead to a longer term strategy for 
poc product opportunities in emerging and 
developing world infectious diseases
allergy automation
the group remains focused on launching 
a panel of approximately 40 allergy tests 
on the automated idsisys instrument 
by the end of march 2014 and the recently 
announced achievement of ﬁnalising the 
assay protocol on which all remaining 
development will take place along with 
the intention to appoint ids as distributor 
in their core markets of the uk germany 
france the nordic regions and the us 
means we remain committed to building 
a signiﬁcant presence in the growing 
automated allergy testing market
market strategy – bric focus
the ivd industry as a whole has seen a 
slowdown in growth during 2012 as the 
major european us and japanese markets 
have experienced increased pressure on 
reimbursement levels and cuts in national 
health expenditure by contrast the emerging 
markets particularly india and china have 
continued to experience doubledigit growth 
rates the group’s decision to set up its 
own subsidiary in india nearly two years ago 
appears prescient against this backdrop and 
is expected to achieve growth both with our 
existing food intolerance products and the 
recently launched allergodip
®
 doctor’s ofﬁce 
test both china and brazil are topﬁve 
markets ranked by sales of food detective
®
 
and the relationship with hob biotech in 
china is expected to deliver further growth 
in this market
board and employees
i am very pleased that we have been able 
to attract and appoint bill rhodes as a 
nonexecutive director to the board and 
look forward to working with him given 
his knowledge and experience built up 
over many years particularly with becton 
dickinson as we implement our strategies 
outlined above mike gurner has decided 
to retire and step down from the board 
with immediate effect i would like to thank 
mike for his contribution over the many years 
since the group became a public company 
and i on behalf of the board wish him all 
the best in his retirement
outlook
more than half of group turnover is generated 
in the uk and europe predominantly through 
the food intolerance and allergyautoimmune 
divisions the economic uncertainty in this 
region has led to a slowdown in growth in 
european ivd markets and the ability to grow 
our own business is not immune from the 
broader landscape in germany in particular 
the reimbursement picture remains uncertain 
and the early pollen season has once more 
suffered from some of the wettest weather 
seen in northern germany for many years 
sales in the middle east have also got off to 
a slower start in part linked to the political 
situation to counter risk in these areas we 
have a strategy to focus on the emerging bric 
markets and our success in growing revenue 
in the year ahead will be dependent on 
whether sales into these higher growth 
territories can compensate for the pressures 
being experienced in europe and elsewhere
beyond the immediate term our ability to 
drive growth will be best delivered through the 
successful commercialisation of the cd4 test 
and automated allergy tests on the idsisys 
instrument a signiﬁcant amount of progress 
has been made in the past year and it is now 
time to deliver on these strategies
