There are tests that can show if you have a current infection and tests that show if you have already had a COVID-19 infection and have developed antibodies.
PCR-tests and rapid antigen tests show if you have an active COVID-19 infection. The PCR test is used today on a large scale. It detects the virus’s genetic material. An antigen test shows if there are viral proteins in the sample.
An antibody test shows if a person has previously been infected with COVID-19 and has developed antibodies in response to the virus. An antibody test is taken 2–3 weeks after falling ill. We recommend that antibody tests be taken by health care providers.
