Types of SARS-COV-2 Tests
Antigen Tests - Antigen tests are immunoassays that detect the presence of a specific viral antigen. Most can be processed at the point of care with results available in minutes and thus can be used in screening programs to quickly identify those who are likely to be contagious.
Antibody Tests - Authorized for Emergency Use by the FDA, IgG/IgM Rapid Antibody Test tests for antibodies associated with a previous COVID-19 infection. Antibody tests are recommended for anyone which suspects a previous COVID-19 infection. Antibodies are detectable within 4 to 7 days of infection. Results in less than 30 mins with a simple finger stick. Note: Antibody test results should NOT be used to make any medical or COVID-19 vaccination decisions.
PCR Tests (Polymerase Chain Reaction) - PCR tests detect one or more viral ribonucleic acid (RNA) genes and indicate a current infection or a recent infection but, due to prolonged viral RNA detection, are not always direct evidence for the presence of virus capable of replicating or of being transmitted to others. PCR tests can be performed via saliva or blood samples. Results in 30 minutes.
