Scientists urge urgent investigation to ensure that people are not being given false negative results
Scientists are calling for an urgent investigation after dozens of reports of people testing negative using gold-standard Covid PCR tests, despite testing positive on rapid lateral flow tests, and in many cases experiencing Covid-like symptoms.
The UK Health Security Agency (UKHSA) said it had been made aware of people in some areas of the country anecdotally reporting positive lateral flow test results with subsequent negative PCR tests, and that it was looking into the cause.
