COVID-19 Testing Q&A

What is rapid COVID-19 testing?

The antigen test, also called the rapid test, usually involves a nose swab. Your provider inserts a long swab into each nasal cavity, collecting a sample for testing. Antigen tests check for proteins made by the COVID-19 virus.

If the antigen test detects these proteins, you’re presumed positive for COVID-19. Antigen tests produce a positive or negative result after only 10 minutes, so you can wait for your results before you leave.

What is PCR COVID-19 testing?

The polymerase chain reaction (PCR) test checks for genetic material from the novel coronavirus. As with the antigen test, the PCR test involves nasal swabbing.

Many people have the antigen and PCR tests at the same time. It takes a few days to get results from the PCR test because it requires lab testing. PCR tests are the most accurate way to determine whether you have COVID-19.

What is the COVID-19 antibody test?

The antibody test is a blood test that checks for antibodies that the body produces to fight COVID-19. This test may indicate whether you previously had COVID-19 but doesn’t detect a current infection.

If you’re fully vaccinated, you may have a positive antibody test because the vaccination encourages your body to make antibodies. The FDA recommends against vaccinated or unvaccinated people using antibody tests to evaluate their level of protection from COVID-19.

When should I have COVID-19 testing?

The Centers for Disease Control and Prevention (CDC) recommends COVID-19 testing in several situations. Regardless of your vaccination status, if you have symptoms of COVID-19, or if your employer, school, or someone else requires testing, you should arrange one promptly.

If you’ve been around someone with COVID-19, you should have a test at least five days after the last contact with that person. If you’ve been exposed to an infected person and you had COVID-19 within the past three months, you don’t need to test unless you develop new symptoms.
