O ganlyniad i’r mesurau rheoli ansawdd ar gyfer profi mewn labordai a diwydrwydd staff labordai Iechyd Cyhoeddus Cymru, daethom yn ymwybodol ddydd Gwener 15 Ionawr 2021 am fater sy’n effeithio ar nifer fach o swabiau a ddefnyddir at samplu am Covid\-19\.


Defnyddir y swabiau hyn i samplu am Covid\-19 mewn ysbytai, mewn unedau profi cymunedol a reolir gan fyrddau iechyd, ac unedau profi symudol a reolir gan Wasanaethau Ambiwlans Cymru (WAST).  Ni ddefnyddir y swabiau hyn gan y labordai Lighthouse felly mae profion a wneir drwy ein safleoedd profi rhanbarthol a lleol heb eu heffeithio.


Cyn gynted ag y darganfuwyd y broblem, rhoddwyd gwybod i bob labordy microbioleg a chanolfan brofi yng Nghymru fel y gellid tynnu’r swabiau yr effeithiwyd arnynt o’r system.


Mae Partneriaeth Cydwasanaethau GIG Cymru (NWSSP) yn gweithio gydag Iechyd Cyhoeddus Cymru, Byrddau Iechyd Lleol, gwneuthurwr y swabiau, COPAN a’r cyflenwr/dosbarthwr i’r DU, Thermo Fischer Scientific, i nodi ac ynysu’r swabiau yr effeithir arnynt o bosibl i atal eu defnyddio mwyach.


Anfonwyd y swabiau yr effeithir arnynt i Gymru yn uniongyrchol oddi wrth y gwneuthurwr COPAN rhwng 18 Tachwedd a 14 Rhagfyr 2020\.  Mae NWSSP wedi ynysu’r holl gyflenwad perthnasol yn rhagofal wrth gynnal ymchwiliadau pellach.


Cyngor Iechyd Cyhoeddus Cymru yw, pan y defnyddiwyd y swabiau hyn, nad ydynt yn achosi dim neu fawr ddim risg i iechyd y cyhoedd.  Er diogelwch, gwneir mwy o wiriadau.  Gallai’r fater a ganfuwyd fod wedi effeithio ar gywirdeb cyfran fach o ganlyniadau prawf, gan arwain at ganlyniadau positif anghywir.  Fodd bynnag, ar sail yr hyn a wyddwn ar hyn o bryd, mae Iechyd Cyhoedd Cymru yn hyderus nad yw’n cael effaith ar y darlun epidemiolegol cyffredinol.


Mae’r system Profi, Olrhain, Diogelu yn parhau i weithredu fel arfer a defnyddir swabiau gwahanol.

As a result of the laboratory testing quality control measures in place and the diligence of Public Health Wales laboratory staff, we became aware on Friday 15 January 2021 of an issue affecting a small number of swabs used in sampling for Covid\-19\. 


These swabs are used to sample for Covid\-19 in hospital settings, at health board\-run community testing units and WAST\-operated mobile testing units. These swabs are not used by the lighthouse labs and so tests undertaken through our regional and local testing sites are unaffected.


As soon as this problem was discovered, all microbiology labs and testing centres in Wales were notified so that the affected swabs could be taken out of circulation.


NHS Wales Shared Services Partnership is working with Public Health Wales, Local Health Boards, the manufacturer of the swabs COPAN and the UK supplier/distributor Thermo Fisher Scientific to identify and isolate the swabs potentially affected to prevent their on\-going use.


The affected swabs were shipped into Wales direct from the manufacturer COPAN between 18 November and 14 December 2020\. NHS Wales Shared Services Partnership has isolated all relevant supplies as a precaution while further investigations are undertaken.


Public Health Wales have advised that where these swabs have been used they pose little or no risk to public health. As a safeguard, further checks are being undertaken. The issue detected may have affected the accuracy of a small proportion of test results leading to false positives. However, based on what we currently know Public Health Wales is confident that this does not affect the overall epidemiological picture.


The Covid\-19 Test, Trace, Protect system continues to operate as normal and alternative swabs are being used.
