The PCR test shows a virus, whether it is an active virus or an inactivated virus, which can be tested positive several days, weeks and months after the infection.

It is incredibly individual if you test positive when you no longer have symptoms after a covid infection. Some people can test positive months after the disease while some test negative as soon as they have become symptom-free. The risk of getting a positive result gets lower by every day.

Both antigen tests and PCR tests can show positive even if you no longer have symptoms as long as there are still traces of the virus in the body.
