It is important that we do NOT retest (PCR or Rapid) for 90 days following a positive test / confirmed Covid-19 infection as this may well show a false positive AND that positive will still require isolation as per UK law.

Information below is from Public Heath England answering the question ‘What is the policy on testing after a positive result / confirmed Covid-19 infection’ :

“It is possible for tests to detect residual virus for some time after COVID-19 infection. Anyone who has previously received a positive test result for COVID-19 should only be re-tested within a 90-day period if they develop any new symptoms of COVID-19. As such, if it is within this timeframe and the individual does not have new symptoms, they should not need to self-isolate again.”
