Test Overview
A COVID-19 viral test is a way to find out if you have COVID-19. The test looks for the virus in your breathing passages. There are different types of viral tests.
One type looks for genetic material from the virus. This is usually called polymerase chain reaction (PCR).
Another type looks for proteins on the virus. This is usually called an antigen test. It may not be as accurate as PCR.
Some test results come back in a few minutes. Others may take a few days.
If you have questions about COVID-19 testing, ask your doctor or check the CDC website at cdc.gov for information.
