There are a few options for viral COVID-19 tests. The main two types of tests are PCR tests and rapid antigen tests:

PCR Test (NAAT is an alternative name)

  • Most accurate test currently available 
  • Typically administered by health providers at a clinic or pharmacy and analyzed in a laboratory
  • Results in typically in 24-72 hours

Rapid Antigen Test

  • Less accurate than PCR tests
  • Results in as little as 15 minutes when taken at home
  • Can be self-administered with an at-home testing kit, or taken at a testing site

There’s another kind of test known as an antibody test, which can help indicate whether you have had COVID-19 in the past. Antibody tests are used by scientists to better understand the virus, but they are not used to determine whether you currently have an infection.
