COVID 19 PCR - Overview
A COVID 19 PCR, or polymerase chain reaction, test is a test used to detect genetic material from the COVID 19 virus. The test will detect the virus if you have the virus at the time of the test. COVID 19 PCR tests are used to determine if you have COVID 19.
COVID 19 PCR - Testing
A COVID 19 PCR test is a molecular test that analyzes your upper respiratory specimen, looking for genetic material from the virus that causes COVID 19. Testing is most commonly done through a nasal swab. Through the tests, clinicians amplify small amounts of RNA from specimens in DNA, which is replicated when the COVID 19 virus is present. This has been the gold standard to diagnose COVID 19 since the virus first became widespread in 2020.
COVID 19 PCR - Testing Labs
Testing labs for COVID 19 PCR tests are widespread across the United States. Check for locations of labs in your area by visiting the CDC’s website or the website of your local health care provider.
COVID 19 PCR - Testing results
A positive test from a COVID 19 PCR test means that it’s likely that you have an infection from the virus that causes COVID 19. A negative test result means that you didn’t have an infection with the virus that causes COVID 19 at the time you took the test. This doesn’t necessarily mean you don’t have COVID 19, you could have a low-level of the virus present, or you didn’t have the virus when you were tested. Consider taking another test if symptoms persist or worsen.
COVID 19 PCR Testing Online
COVID 19 PCR tests must be done in person, but tests can be scheduled online.
How long will it take to get my results?
You should receive COVID 19 PCR testing results in as little as 24 hours after you’ve been tested, but sometimes it takes a few days to get test results back.
