chairman’s statement
osmetech has continued to make significant progress with its strategy to developa diagnostics
business in the fast growing near patient testing market serving small to medium sized hospitals
the two recent acquisitions ofofexlistedmolecular sensing plcandclinicalmicrosensorsinc
“cms” frommotorolainc havecreateda strongand unrivalled product combination opti
gene will target simple test applications suchas sexually transmitted diseases where thereis
oftena demand for fast results thecms esensor™ product is suitable for morecomplex tests
suchas cysticfibrosis where theanalysis of multiple gene targets is required as thehuman
genomeproject continues to provide the genetic information necessary for new tests these
products createa strategically strong position for osmetech in the fast growing market segment of
genetic diagnostics
theoptibusiness has again performed well in the year it provides us withan excellent platform
from which wecan develop new product opportunities within thegroup this proven operational
infrastructure willbe very valuable in the process ofbringing theoptigeneand esensor™
products through to market weanticipatebeingable to successfully leverage our skills in
instrument manufacturingas wellas benefiting from our strong international distribution network
that currently sell toa similar customer base of small to medium sized hospitals
iam delighted to welcomebrucehuebner andgeoffmckinley to the management teamboth of
whom haveconsiderable experience in the field of genetic diagnostics bruce joins thegroupas

biology business successfully inlicensing technology fromgenprobeandaffymetrix 
injuly 2005osmetech raised £102 million net of expenses by way ofa placing of new shares in
order to provide workingcapital for thegroup througha very exciting stage in our development
we recognise the support andcommitment of many of our long term shareholders and had
originally proposed to provideall existing shareholders with the opportunity to participate in the
fundraising throughan offer of shares ona preemptivebasis however particularly in view of the
new europeanprospectus directive that became effective injulyand the increased timeandcost
that would havebeen involved in preparing suchan offer we reluctantly concluded that to
proceed on this basis would not be in thebest interests of thecompany 
at the forthcomingannualgeneralmeeting tobe held on 30 september 2005a resolution willbe
proposed toconsolidate every 10 ordinary shares of 001p each into 1 ordinary share of 010p each
weexpect to launchboth theoptigeneand esensor™ products in thecoming months and with
osmetech underpinnedby the strength of theoptibusinessibelieve that weare very well
placed tobuilda successfuland fast growing international diagnostics business

chief executive officer’s review
introduction
wearenow building upon the highly reliable revenue platform that opti has provided the
completion of twoacquisitionsmolecular sensing plc “ms”andclinicalmicrosensorsinc
“cms” in the fastest growth sector of the global diagnostics market genetic diagnostics should
providea powerful product combination this shouldallow us toperformboth simple tests
throughoptigeneand morecomplex tests with thecms esensor™ instrument yielding
exciting international opportunities for the further growth of thegroup 
as with theacquisition ofopti fromroche in 2003 theseacquisitions werecompleted on
favourable terms for osmetech shareholders and we expect tobeable to extract considerable
value from these investments in duecourse
opti
the recent investment in new opti products is starting to pay off with the updatedcca with
touchscreen havingbeen successfully launched the reusableoptir instrument targeting higher
usagecustomers and theoptilion electrolyte only analyser exhibitedat the recent american
association ofclinicalchemists conference aacc meeting in theus were very well receivedby
bothcustomers and international distributors both of these products are scheduled for worldwide
launch later this calendar year
theopti product line of near point ofcarearterialblood gas analysis instruments and
consumables continues to show good underlying sales growthas the market continues to migrate
from traditionalcentral hospital laboratory settings sales revenues for the year increased
marginally inconstant currency terms and there was underlying growth in excess of 10after
accounting for the oneoffbenefit ofsarsrelated sales tochinaand initial distributor pipeline
filling during the prior year
the vetstat productanopticcaanalyser adapted for the veterinary market has now been
launchedby our distribution partneridexxlaboratoriesinc “idexx” producing most
encouraging early results with orders exceeding expectations idexx is a worldwide leader in the
development andcommercialisation ofanimal health diagnostic products and weareconfident of
future growth resulting from their extensive sales and marketingcampaigns
good progress has alsobeen made with the development contract withidexx tocreatea new
platform for measuringcriticalcare parameters based onosmetech’s proprietary optical
fluorescence technology weexpect product sales tocommence on schedule in the short to
medium term
weopeneda sales office ingermany inapril with exclusive distribution rights toopti products in
this important market where we havean existingcustomer base regularly orderingconsumables
we shouldbeable to successfully leverage this operation further as we introduce new opti
products andcomplementary third party products we willalso havean established operation
through which to launch thegroup’s genetic diagnostics products allowing us to service the
customer base directly
opti is well placed to grow steadily andas the installedbaseexpands producea high quality
and reliable income stream for thegroup
genetic diagnostics market
genetic diagnostics is the fastest growing segment of the global diagnostics market and in theus
is forecast to grow at approximately 20 per year during the next 5 years the growth of this 4 osmetechannualreport 2005
chief executive officer’s review continued
sector and the prospect of high profit margins is becoming of increasing interest across the wider
diagnostics industry roche have recently madea strategic investment inaffymetrix which has a
biochip for dna detection
the genetic diagnostics market has not been dominatedby the major companies most testing is
currently performedby large hospitals and reference laboratories operating expensive instruments
and running specialised tests which rely on high volume testing in order to managecosts
the growth in these highly accurate diagnostic tests is expected tobe drivenby technological
advances providing simpler and morecost effectiveassays to enable small to medium sized
hospitals to perform testing themselves inaddition to the expansion of thehumangenome
project resulting in new tests to reduce healthcare systemcosts and to improve patient care this
fits well withosmetech’s existing distributor networkandcustomer base
the following three subsegments account for over 75 of theus genetic diagnostics market the
genetics and pharmacogenomics market in theusalone is expected to increase from 120m to
950m over the period 20032010 over the same period theus infectious diseases market is
expected to grow from 675m to 18bn
1humangenetics
human genetics focuses on enabling the physician to test individuals for diseases for which they
havea genetic predisposition for examplecystic fibrosis thrombosisalzheimer’s or certain
cancers this is achieved through the detection of “mistakes” inan individual’s dna which may
cause mutations associated witha particular disease
2pharmacogenomics
pharmacogenomics is the process of developing drug therapies tailored toan individual patient’s
needs through genetic testing this enables physicians to ensure that treatments areboth safeand
effective reducing drug wastageand reducing the possibility of patients experiencingadverse
drug reactions this is anarea in which weanticipate rapid growthand perhaps for the first time in
the healthcare diagnostics industry we will see pharmaceutical marginsbut without theassociated
development costs and timescales
thefda has recently approveda new product fromrocheaffymetrix for thecyp450 family of
enzymes which will provide relevant genetic information for drug metabolismand has now been
launchedat more than 500 per test cmsalso has a product currently under development for
cyp450 which is planned tobe launched later in 2006

3infectious diseases
healthcare physicians rely on tests whichareable to identify thedna of thebacteria responsible
for sexually transmitted diseases eghivchlamydia gonorrhoeaand other infectious diseases
suchas mrsa this is the largest sector of the genetic diagnostics market today and is
concentrated incentral laboratories whichbatchand test high volumes of samples osmetech’s
aim through its optigene instrument is to improve the turnaround time of testing in this area
sufficiently to justify a shift in testingaway from thecentral laboratory to near point ofcare an
easy to perform test whichcan providea result within 45 minutes whilst the patient is stillat the
hospital or clinic presents a significant opportunity tocontrol the spread of diseaseboth in the
hospitaland in the general population theseattributes arealso expected tobe useful for the
effective diagnosis for emergingcontagious diseases suchas birdflu 
osmetech’s genetic diagnostics strategy
strategically the progression into genetic diagnostics was a logical move for osmetech with strong
growthanticipated from the small to medium sized hospital market  our corecustomer base we
hadbeen evaluatinga number of potential tests and technologies tocombine with our ownfda
approvedbacterial vaginosis test withina devicecapable of diagnosingand differentiatingbetween
the most prevalent andclinically important vaginal infectionsduring this process we reviewedand
assessed thecollaborative work that lgclimited “lgc”andms hadbeen performing includinga
successful study ofclinical samples at theroyalfreehospitalinlondon to evaluate thelgc
hybeaconchlamydia detectionassay run on the prototypeoptigene instrument we now intend
to developand market theoptigene deviceas a priority toaddress the most critical
requirements of the vaginal infectionand sexually transmitted diseases market
webelieve that theopttigeneand esensor™ products have theattributes necessary to meet
the requirements of the hospital market for new genetic tests that emerge from the expansion of
thehumangenomeproject that only require theanalysis ofa limitedamount of genetic
information the rapidoptigene product is well suited the esensor™ device is designed for
morecomplex tests 
both of these products facilitateaccurate testing inacost effective easy to use format andare

osmetech shares for every 2 ms shares resulted ina total of 83992581 new osmetech shares
being issued withanaverage midmarket price of 3245 pence per share this valuedmsat
approximately £27m at the date ofacquisition the fair valueof the net assets ofms was £18m

opti gene
optigene is a rapidand easy to use device for dnaandrnaanalysis for relatively simple tests
that require limited genetic information suchas thrombophiliaand infectious diseases including
sexually transmitted diseases
we have signedan exclusiveagreement withlgc to license its hybeacons dna probe
technology for genetic testingapplications inall world markets excludingindia assays utilising
this technology arebeing developedat our facility inbostonus 
the development programme for thecompletion of theoptigene instrument has been fully
integrated intoosmetech’s operations we plan to exhibit the product at themedica europeand
amp us trade shows innovember this year with product sales likely tocommence in the first half
of 2006
optigenealso has significant potential in other markets suchas veterinary forensics and
research we would seek to exploit these opportunities through strategic partnerships as we have
achieved through the existingidexx relationship
we havealso signeda license withrochediagnostics for our proprietary plastic tube technology
the worldwide nonexclusive license will enableroche to manufactureand sell plasticconsumable
vials for use on its large installedbase oflightcycler instruments as a morecosteffective
alternative to existing glass vials whilst maintaining performance levels the same technology has
been incorporated intoconsumables tobe supplied for use withosmetech’s optigene
instrument
acquisition of clinical micro sensors inc
cms was acquiredcashand debt free on 26 july 2005 for aconsideration satisfiedby an issue of
warrants that entitlemotorola to subscribe for 78114287 ordinary shares at 175 pence per share
under the terms of theacquisitionmotorola havealso subscribed for 212470862 ordinary shares
inosmetech equating toan investment of £37m
cms
cms was founded in 1994as a spin off fromthecaliforniainstitute of technology “caltech”and
was acquiredby motorola injune 2000 for aconsideration of 280m thebusiness is based in
pasadenacaliforniausand employs approximately 60 people
motorola has disposed of its noncore medicalbusinesses includingcms osmetech identified
this business as having excellent core technology with strong intellectual property protectedby
international patents which hadbenefited from significant investment by motorola during its
period of ownership
thecore technology ofcms is electrochemical detection for dnaanalysis cms has been
developinga low cost instrument andconsumable for moderately complex genetic testing where
the detection of multiple gene targets is required thecms esensor™ instrument is a platform
that allows a number of tests tobe performed through the use ofacommonconsumable
configured for a specific test webelieve that both the instrument andconsumable have
significant cost advantages over competitor products
cms has developeda test for cystic fibrosis carrier screening where the presence of 25 genes is
analysed froma single sample clinical trials havebeenconductedat two hospitals and one
reference laboratory in theus to support a 510k submission to thefda oneclinical laboratory osmetechannualreport 2005 7
chief executive officer’s review
continued
oregonhealthandscienceuniversity recently presenteda research poster ‘biochipbasedcystic
fibrosis carrier screening’ that discusses theclinical methodsand results using thecms
esensor™ dna detection system the paper notes that thecms system producedaccurateand
timely results was easy to use with straightforward sample preparation it concluded that this
biochip system wouldbe useful for moderate volume testing the paper is available on our
website wwwosmetechcom 
we plan to exhibit thecms esensor™ cystic fibrosis product at themedica europeandamp us
trade shows innovember this year with product sales anticipated tocommence in the first half of
2006
cms’s second product launch is likely tobe for cyp450anarea that we expect to grow rapidly
intoa significant market this product is anticipated for launch towards the end of 2006
fund raising
at the same timeas theacquisition ofcms injuly 2005a placing of 6286m ordinary shares raised
£110m gross £102m net of expensesat a price of 175 pence per share following the
completion of the placing thereare 1318049730 ordinary shares in issue the placing was largely
with new investors includingmotorola who subscribed for £37m this will provide funds for the
enlargedgroup’s workingcapital requirements particularly that which relates to the new cms
business 
webelieve that net proceeds of the funding willbe sufficient for thecompletion of development
and the launch ofboth theoptigeneandcmscystic fibrosis products however it is likely that
osmetech will require further funding in the futurebut we expect tobeable toachieve this froma
position of strengthas webuild value within thegroup
financial review
sales revenues totalled 10863000 £5833000 which representeda 4 increase over the
previous year onaconstant currency basis 10453000 £6180000 the 6 reduction in sales
reported in sterling reflects the relative weakness of theus dollar during the period 
opti sales accounted for 98 of total revenues andas has already explained this business
experienced underlying growth in excess of 10 in product terms the highly reliable repeat
reagent sales accounted for 63 of total revenues
as expected gross profit margins reduced to 415 from theabnormally high levels achieved in
the previous year following the successful utilisation of slow moving inventory acquiredas part of
the purchase of theoptibusiness a high proportion ofopti’s cost of sales represents fixed
manufacturingcosts the recovery of which will improve throughadditional production volumes
fromidexxand new product introductions with minimal sales and marketingcosts through the
use of distributors for internationaland veterinary market sales we expect tobeable to improve
the profitability of thebusiness as revenues continue to grow
operating losses before exceptional items of £827000 2004 – £nil increased to £2152000 2004 –
£1418000 largely as a result of the reduction in gross margins explainedabove other non
exceptional overheads of £4574000 2004 – £4864000 representeda reduction of 6compared
to the prior year although much of this reduction was explainedby currency movements this year
includes overheads relating to themsoptigenebusiness since its acquisition on 12 october
2004 together withcosts associated with the due diligence process for thecmsacquisition 8 osmetechannualreport 2005
chief executive officer’s review
continued
we have recognised exceptionalcosts this year of £827000although only £67000 represents
‘cash items’ and relates to the integration of themsacquisition noncash items comprise the
write down of thecarrying value ofcertain tangibleand intangibleassets including £681658
relating to electronic gas odour sensor technology following thegroup’s change in strategy to
focus its development resources primarily on genetic diagnostics
cash outflows before financingamounted to £1227000 2004 – £2104000although this included
£1691000 net cashacquired from theacquisition ofms adjusting for this the gross outflow of
£2918000 was broadly similar to the reported loss for the year the £760000 noncash elements of
the exceptionalcosts were offset by a largely temporary increase of £553000 in trade debtors due
to the strong sales performance towards the end of the trading period
in order tobring our reporting periodand naturalbusiness cycle in line with that of our
commercial partners we intend tochange our accounting period toadecember year end we will
therefore report for an 8 month period ending 31december 2005
outlook
lookingahead for opti we expect continued strong growth through theidexx trading
relationshipandan increasedcontribution from the launch later this year of theoptilionand
optir instruments
we havea high quality operational infrastructurecapable of supporting thecontinued growth of
thebusiness and have the skills experienceand knowledge of the market to exploit the significant
opportunities that lieahead particularly in the field of genetic diagnostics within the genetic
diagnostics sector the small to medium sized hospitalbusiness is expected to grow most rapidly
this is osmetech’s existingcore internationalcustomer base

Summary:

chairman’s statement
osmetech has continued to make significant progress with its strategy to developa diagnostics
business in the fast growing near patient testing market serving small to medium sized hospitals
the two recent acquisitions ofofexlistedmolecular sensing plcandclinicalmicrosensorsinc
“cms” frommotorolainc havecreateda strongand unrivalled product combination opti
gene will target simple test applications suchas sexually transmitted diseases where thereis
oftena demand for fast results thecms esensor™ product is suitable for morecomplex tests
suchas cysticfibrosis where theanalysis of multiple gene targets is required as thehuman
genomeproject continues to provide the genetic information necessary for new tests these
products createa strategically strong position for osmetech in the fast growing market segment of
genetic diagnostics
theoptibusiness has again performed well in the year it provides us withan excellent platform
from which wecan develop new product opportunities within thegroup this proven operational
infrastructure willbe very valuable in the process ofbringing theoptigeneand esensor™
products through to market weanticipatebeingable to successfully leverage our skills in
instrument manufacturingas wellas benefiting from our strong international distribution network
that currently sell toa similar customer base of small to medium sized hospitals
iam delighted to welcomebrucehuebner andgeoffmckinley to the management teamboth of
whom haveconsiderable experience in the field of genetic diagnostics bruce joins thegroupas
president ofcms he was previously chiefoperatingofficer ofgenprobeandpresident and
chiefoperatingofficer ofnanogen two major internationalcompanies in the genetics and
infectious diseases markets bruce has a strongsales andmarketingbackgroundand oversaw
genprobe througha period of growthandcommercial success in the diagnostics industry geoff
mckinley is responsible for our optigenebusiness he was previously sr director business
development biomérieux na with responsibility for new technologies for this globalmolecular
biology business successfully inlicensing technology fromgenprobeandaffymetrix 
injuly 2005osmetech raised £102 million net of expenses by way ofa placing of new shares in
order to provide workingcapital for thegroup througha very exciting stage in our development
we recognise the support andcommitment of many of our long term shareholders and had
originally proposed to provideall existing shareholders with the opportunity to participate in the
fundraising throughan offer of shares ona preemptivebasis however particularly in view of the
new europeanprospectus directive that became effective injulyand the increased timeandcost
that would havebeen involved in preparing suchan offer we reluctantly concluded that to
proceed on this basis would not be in thebest interests of thecompany 
at the forthcomingannualgeneralmeeting tobe held on 30 september 2005a resolution willbe
proposed toconsolidate every 10 ordinary shares of 001p each into 1 ordinary share of 010p each
weexpect to launchboth theoptigeneand esensor™ products in thecoming months and with
osmetech underpinnedby the strength of theoptibusinessibelieve that weare very well
placed tobuilda successfuland fast growing international diagnostics business
