43,000 in UK may have received false negative Covid-19 test results

British health officials said on Friday that 43,000 people may have been wrongly told they do not have the coronavirus because of problems at a private laboratory. The UK Health Security Agency said the Immensa Health Clinic Ltd. lab in Wolverhampton, central England, has been suspended from processing swabs after the false negatives. Will Welfare, the agency’s public health incident director, said it was working “to determine the laboratory technical issues” behind the inaccurate tests.
