      • Antigen tests (also known as rapid tests) are diagnostic tests and not screening tests for patients with signs or symptoms consistent with COVID-19. Antigen tests are not as sensitive as nucleic acid amplification (including PCR) tests, there is a higher chance of false negatives, thus negative results do not rule out infection and may need to be confirmed with a nucleic acid amplification testing prior to making treatment or isolation decisions (see CDC Testing Basics).
