Choosing the Right Test

There are two main types of tests you can use to find out if you have COVID-19:


Rapid antigen tests (also called home tests):

Click for more information about home tests. If you have COVID-19 symptoms, you should get tested right away and stay home except to get medical care.


These tests:

  • Give results in 15-30 minutes

  • Can be bought over the counter and done at home (they are also offered at many clinics as well)

  • Are very good at detecting an active infection if you have symptoms, but may not detect an infection if you don’t have symptoms


Molecular tests

(also called PCR tests, viral RNA tests, nucleic acid tests):

Free molecular COVID-19 tests are available at county sitesState sites and other commercial and healthcare provider sites.


These tests:

  • Are very sensitive and accurate, meaning that they can detect an active infection even if you don’t have symptoms

  • Have a slower turnaround time for test results than rapid tests (usually 24-48 hours)

  • Cannot be done at home

  • May remain positive for days or even weeks after the person is no longer infectious
