What you need to know about COVID-19

What are the types of coronavirus tests?

There are two basic types of tests for COVID-19.

Viral test: This test can tell you if you are currently infected with the coronavirus. A swab is placed in the nose or mouth to gather samples. There are two types of viral tests: laboratory tests (sometimes called polymerase chain reaction [PCR] tests), and rapid tests that detect portions of the virus called antigens.

Laboratory coronavirus tests are given by health care professionals, and results are available within 12 hours, Since the samples are analyzed in a laboratory, they are very accurate and are often recommended for people with COVID-19 symptoms. Laboratory tests sometimes require an additional test to confirm results.

Should I get a coronavirus test?

The answer varies based on many factors including your symptoms, exposure history and underlying risk factors for severe disease.

A rapid test is useful as a preventive measure if you are traveling or if you do not have symptoms but think you may have been exposed to the coronavirus that causes COVID-19. Other important prevention tools are: getting fully vaccinated and receiving a booster when eligible, wearing a mask, maintaining physical distance and frequently washing your hands.

A viral test is important when a person has COVID-19 symptoms, particularly if they are moderate to severe. A viral test may also be helpful for a person with mild symptoms. People with any symptoms should contact us for a confirmatory test.
