You’ve been exposed to COVID-19. Now what?

While the virus has been dominating headlines, the path to positive (or negative) can still be confusing for those who need to get tested. Are all tests the same, or does one stand out above the rest?

Two of the most common testing options are the PCR test and the antigen test, both of which are typically administered through a nasal swab.

Dr. Elizabeth Ransom, executive vice president and chief physician officer of Baptist Health, outlines the differences between the two in the infographic below.

Ransom said above all else, if you’ve been exposed to COVID-19, you should isolate to protect yourself and your loved ones, regardless of a test result.

If you decide to get tested, it’s OK to start with an antigen test and then proceed to get a PCR test if you develop symptoms, even if your antigen test was negative.

Criteria for testing may vary by location. A full list of testing sites in Jacksonville is available at jaxready.com/covidtesting.
