A COVID-19 testing laboratory in central England has been suspended more than concern that it has been incorrectly providing unfavorable PCR test final results to persons who are infected, the UK Health Security Agency (UKSHA) stated on Friday.
NHS Test and Trace launched an investigation into a lab in Wolverhampton immediately after reports of persons having unfavorable PCR test final results immediately after testing positive on speedy lateral flow devices (LFDs).
Government suggestions says PCR tests are more correct than LFDs, and persons can quit self-isolating if a positive LFD outcome is followed by a unfavorable PCR test outcome.
UKSHA stated that an estimated 43,000 persons may well have been provided incorrect unfavorable PCR test final results, mostly in southwest England, possibly underestimating the quantity of persons with coronavirus among Sept 8. and Oct. 12.
“We have immediately suspended testing at this laboratory while we continue the investigation,” stated Dr Will Welfare, Public Health Incident Director at UKSHA.
“There is no evidence of any faults with LFD or PCR test kits themselves and the public should remain confident in using them and in other laboratory services currently provided.”
Immensa Health Clinic, who run the lab, stated they have been “fully collaborating” with UKSHA in the investigation.
UKSHA stated it was an isolated incident in one laboratory, with samples now getting redirected to other labs, and general testing availability was unaffected.
But some scientists raised alarm that the false negatives could have contributed to the spread of infections, which are now at their highest level given that July.
“We now know 43,000 people are believed to have been given false negatives, but this doesn’t even come near to the cost of the mistake,” Kit Yates of the University of Bath’s Department of Mathematical Sciences stated.
“Many of these people will have been forced into school or work potentially infecting others. This could be part of the reason behind some of the recent rises we’ve seen.”
