Court papers reveal how long watchdog knew of potential problems at Wolverhampton site
The government’s health watchdog knew about anomalous tests at a private laboratory that gave at least 43,000 people potentially false negative Covid results almost a month before it took action, it emerged.
The UK Health Security Agency (UKHSA) was alerted on 14 September this year to “an unusual spike” in the numbers of people testing positive on lateral flow tests, but negative on supposedly more accurate PCR tests processed by the Wolverhampton lab Immensa, court papers have shown.
