COVID-19Common questionAre the COVID-19 PCR tests accurate?PCR tests are very accurate when properly performed by a health care professional, but the rapid test can miss some cases.
Are there different types of COVID-19 diagnostic tests?
COVID-19Common questionAre there different types of COVID-19 diagnostic tests?There are 2 different types of COVID-19 diagnostic tests -- molecular tests and antigen tests. Molecular tests detect the virus that causes COVID-19, SARS-CoV-2. Antigen tests detect specific proteins made by the virus.Jan 7, 2022

What are the different types of COVID-19 tests?
COVID-19Common questionSee full answerWhat are the different types of COVID-19 tests?1. A diagnostic test can show if you have an active coronavirus infection and should take steps to quarantine or isolate yourself from others. Currently there are two types of diagnostic tests molecular (RT-PCR) tests that detect the virus’s genetic material, and antigen tests that detect specific proteins on the surface of the virus. Samples are typically collected with a nasal or throat swab, or saliva collected by spitting into a tube.2. An antibody test looks for antibodies that are made by the immune system in response to a threat, such as a specific virus. Antibodies can help fight infections. Antibodies can take several days or weeks to develop after you have an infection and may stay in your blood for several weeks after recovery. Because of this, antibody tests should not be used to diagnose an active coronavirus infection.Jan 7, 2022
What does my negative COVID-19 test result mean?
COVID-19Common questionWhat does my negative COVID-19 test result mean?Negative test results in persons with known SARS-CoV-2 exposure suggest no current evidence of infection. These results represent a snapshot of the time around specimen collection and could change if the same test was performed again in one or more days.
