At least 43,000 people have received false negative PCR tests in the South West of England while they might have a virus.


It was recognised after many people got positive lateral flow tests after the PCR was negative. A private laboratory Immensa Health Clinic Ltd, based in Wolverhampton was blamed for the false tests.

“We have recently seen a rising number of positive LFD results subsequently testing negative on PCR,” Will Welfare, Public Health Incident Director at the UK Health and Security Agency (UKHSA) said.

The UK Health Security Agency estimated that almost 400,000 samples have been processed in Immensa Health Clinic and the big part of these samples was negative. The agency reported that approximately 43,000 people had been infected and tested negatively between 8 September and 12 October.

The misinformed people might go to the public, work, or school and they were not being self-isolated as they were spreading disease.

The UK Health Security Agency urged people to retest in order to detect COVID-19 infected persons.

The news came after Britain recorded the highest number of 44,556 cases since July on October 14. At least 8,2 million cases of COVID-19 and 138,000 deaths were recorded in a country of some 67 million residents.
