Types of Testing
There are three kinds of tests for COVID-19: PCR/viral tests and serology/antibody tests.
- A PCR or molecular test tells you if you have a current infection. It is taken with a swab in the mouth, nose or throat.
- An antigen test is a newer COVID-19 test that tells if you have a current infection. It is taken with a nostril or throat swab.
- An antibody (serology) test does NOT tell you if you are infected currently. It only tells you if you had a previous infection and currently is not recommended for individual use. It is done through a needle or fingerstick to get a blood sample.
