Test Comparison

PCR-based tests look for the virus's genetic material in saliva or mucus samples to diagnose people who are currently infected with the novel coronavirus. PCR tests take 2 or more days for results.

Antigen tests can be used to screen individuals infected with the virus. These tests are less accurate than antibody and PCR tests, but they are great for detecting new cases. Antigen tests use a nasal or throat swab to detect viral proteins expressed on the outer surface of the coronavirus. Abbott Lab takes 15 minutes.
Antibody tests differ from antigen tests in that they detect the presence of proteins produced by the body in response to a previous infection. An antibody test measures antibodies in the blood to determine if you have had previous infection against the virus and have recovered. MedMira test takes up to 3 minutes.
