How Do COVID-19 Tests Work?

Two types of tests can detect if you have an active Covid-19 infection:

  • Molecular tests (such as PCR tests) detect the virus that causes COVID-19. Sometimes it can take longer to get your results with a molecular/PCR test than with antigen tests because samples must be sent to a lab.
  • Antigen tests detect specific proteins made by the virus. These tests can usually deliver results in 15 to 30 minutes.

Other tests can detect if you have had COVID-19 in the past:

  • Antibody or serology tests detect whether you previously had COVID-19 at some point in the past.
  • They do not detect whether you have an active COVID-19 infection.
