What are the differences between a COVID-19 antigen, molecular and antibody test?

There are different kinds of tests for COVID-19. Molecular tests (also known as PCR tests)detect genetic material from the virus. Antigen tests detect proteins from the virus. Antigen test sare very specific for the virus but are not as sensitive as molecular tests. This means that a positive result is highly accurate, but a negative result does not rule out infection. Another typeof test is an antibody test. A COVID-19 antibody test detects antibodies that have been made by your immune system in response to a previous COVID-19 infection or vaccination. Antibody tests are not suitable to diagnose an active COVID-19 infection.
