If you have tested positive for Covid-19 within the last 12 weeks, you may risk that a new test, whether a PCR or a rapid antigen test, will show a positive result. It is therefore recommended that you do not undergo regular testing during this period.
The only exceptions from the above are:
If you have been contacted by the infection tracing unit as a 'close contact'. In this case, you should follow the public recommendations for getting tested.
If you develop symptoms that are consistent with Covid-19. In this case, you should have a PCR test and not a rapid antigen test.
