Cafodd Llywodraeth Cymru wybod yr wythnos diwethaf am adroddiadau bod nifer uwch na'r disgwyl o brofion llif unffordd positif wedi arwain at ganlyniadau profion PCR negatif a bod Asiantaeth Diogelwch Iechyd y DU (UKHSA) yn ymchwilio i hyn.


Tynnodd y Byrddau Iechyd sylw hefyd at achosion o nifer o ardaloedd yn Ne Cymru a allai fod wedi cael eu heffeithio yr ydym wedi bod yn eu hadolygu gydag Iechyd Cyhoeddus Cymru, gan gysylltu â'r gwaith sy'n cael ei arwain gan UKHSA. 


O ganlyniad i'r ymchwiliadau hyn, mae gwasanaeth Profi ac Olrhain GIG y DU wedi atal gweithrediadau profi a ddarperir gan labordy yn Lloegr ond mae'n effeithio ar rai trigolion yng Nghymru. Mae hyn yn ymwneud â materion technegol yn y labordy sydd wedi arwain at roi canlyniadau anghywir i rai pobl rhwng 8 Medi a 12 Hydref.  Rydym wedi cael gwybod bod y mater hwn wedi'i ynysu i'r labordy hwn ac nid yw'n cynnwys y rhwydwaith ehangach, gan gynnwys labordy IP5 yng Nghasnewydd sy'n prosesu'r rhan fwyaf o samplau o Gymru.


Mae UKHSA wedi ymchwilio i nifer y profion gan drigolion Cymru a broseswyd yn y labordy yr effeithiwyd arno ac maent yn amcangyfrif ei fod yn bosibl bod tua 4,000o bobl wedi cael canlyniadau anghywir.  Rydym yn asesu y bydd y rhan fwyaf o'r profion hyn wedi'u cymryd mewn safleoedd profi ar draws ardal Gwent a Chwm Taf Morgannwg.


Bydd gwasanaeth Profi ac Olrhain y GIG yn cysylltu ag unrhyw un a gafodd brawf o 4 Hydref ymlaen ac a gafodd ganlyniad o'r labordy yr effeithiwyd arno drwy neges destun a/neu e\-bost a'i hysbysu os oedd yn negatif i drefnu apwyntiad i gael ei ail brawf.  Bydd hefyd yn cynghori bod eu cysylltiadau agos sy'n symptomatig yn archebu prawf. Cysylltir â phobl a gafodd brawf a broseswyd yn y labordy rhwng 8 Medi a 4 Hydref hefyd a'u cynghori i gael prawf os oes ganddynt symptomau. Ein cyngor i bawb o hyd yw os oes gennych symptomau i hunanynysu ar unwaith ac archebu prawf PCR.


Fy mhryder uniongyrchol yw'r wybodaeth a'r cymorth i drigolion Cymru yr effeithir arnynt. Rwyf wedi gofyn i Iechyd Cyhoeddus Cymru ddarparu cymorth a chyngor ychwanegol i'r byrddau iechyd yr effeithir arnynt yn ychwanegol at negeseuon cyfathrebu UKHSA. Byddant hefyd yn asesu effaith bosibl y digwyddiad hwn ar gyfraddau achosion ac adroddiadau epidemioleg i Gymru.


Byddwn yn parhau i weithio'n agos gydag UKHSA a gwasanaeth Profi ac Olrhain y GIG ar y canfyddiadau a'r camau gweithredu sydd eu hangen a byddaf yn rhoi'r wybodaeth ddiweddaraf i'r aelodau am ddatblygiadau.

Welsh Government was made aware last week of reports that a higher than expected number of positive lateral flow tests were resulting in negative PCR tests and that this was being investigated by the UK Health Security Agency (UKHSA).


Health Boards also highlighted cases from a number of areas of South Wales that may have been affected that we have been reviewing with Public Health Wales, linking into the work being led by the UKHSA. 


As a result of these investigations UK NHS Tests and Trace has suspended testing operations provided by a laboratory in England but affects some residents in Wales. This involves technical issues at the laboratory that has led to some people being given incorrect results between 8 September and 12 October.  We have been informed this issue is isolated to this laboratory and does not involve the wider network including the IP5 laboratory in Newport that processes the majority of Welsh samples.


UKHSA have looked into the number of tests from Welsh residents processed at the affected laboratory and estimate around 4,000 people may have been given inaccurate results.  We assess the majority of these tests will have been taken at testing sites across the Gwent and Cwm Taf Morgannwg areas.


Anyone who had a test from 4 October and received a result from the affected laboratory will be contacted by NHS Test and Trace by text message and/ or e\-mail and advised if it was negative to book an appointment to be re\-tested.  It will also advise that their close contacts who are symptomatic book a test. People who had a test processed at the laboratory between 8 September and 4 October will also be contacted and advised to get a test if they have symptoms. Our advice to everyone remains that if you have symptoms to self\-isolate immediately and book a PCR test.


My immediate concern is the information and support for the Welsh residents impacted and I have asked Public Health Wales to provide additional support and advice to the affected health boards in addition to the UKHSA communications. They will also be assessing the potential impact of this incident on the case rates and epidemiology reports for Wales.


We will continue to work closely with UKHSA and NHS Test and Trace on the findings and actions needed and I will keep members informed on developments.
