A swab test is performed at a drive-through centre
(Picture: PA Wire)A blunder at a lab which led to thousands of positive Covid-19 cases reported as negative could have led to the deaths of 20 people, new estimates from the UK Health Security Agency show.
The Immensa laboratory, in Wolverhampton, was found to have misreported around 39,000 PCR tests as negative when they should have been positive between September 2 and October 12, 2021 - mainly in the South West of England.
