Somerset’s Public Health leaders have this week advised people to retest if they are still displaying Covid-19 symptoms after receiving a negative PCR test result.
The advice follows a national announcement regarding the suspension of a laboratory processing Covid-19 PCR tests.
An estimated 43,000 people may have been told they didn’t have Covid-19, when they did.
The error is down to issues with Covid PCR tests processed at one lab in Wolverhampton which has now been shut as NHS Test and Trace investigates reports of people receiving negative PCR results despite testing positive on a lateral flow.
NHS Test and Trace estimates around 400,000 samples have been processed through the lab, operated by Immensa Health Clinic Ltd, and the vast majority of these were given negative results.
In recent weeks there have been concerns around a number of people receiving negative PCR test results after they have previously tested positive on a Lateral Flow Device (LFD).
The UK Health Security Agency (UKHSA), formerly Public Health England, says an estimated 43,000 people may have been given incorrect negative PCR test results between 8 September and 12 October, mostly in the South West of England. For those cases that were some time ago there is no need for further action.
NHS Test and Trace is however contacting the people who were tested more recently and could still be infectious to advise them to take another PCR test. Close contacts who are symptomatic will also be advised to take a PCR test in line with normal practice. Anyone with Covid-19 symptoms should book a PCR test. Those with a positive LFD test should also get a follow up PCR test to confirm they have Covid-19.
This has been confirmed as an isolated incident attributed to one laboratory and all samples taken after 12 October are now being redirected to other laboratories.
Professor Trudi Grant, Director of Public Health for Somerset County Council, says: “This is an unfortunate incident that will have affected a significant number of PCR test results across the South West. At present, we are being advised that NHS Test and Trace will be in touch with people that could still be infectious to advise them to take another test.”
“However, if you are in any doubt at all about yourself or a loved one still displaying symptoms and tested before 13 October, please retest using either a home PCR testing kit or by getting a PCR test at one of the local testing sites.”
Councillor Clare Paul, Cabinet Member for Education and Public Health, said: “People should feel reassured that there are no technical issues with the LFD or PCR test kits themselves and no issues at any testing sites; people should continue to test as normal. All other labs are working normally.”
“Our advice remains, if you are showing any symptoms of Covid-19 or have a positive LFD test please stay at home and self-isolate for ten days to avoid infecting others and get a confirmatory PCR test within 48 hours.”
