How do I know that my positive test is accurate?

Every test has some room for error, known as “false negatives” or “false positives.” Tests that are granted Emergency Use Authorization (EUA) by the FDA must have a certain level of accuracy. There is also the possibility for user error. One way to be more sure about your positive test result is to take a second test at the same time or shortly after your first. However, because of how the tests are designed and how accurately they can detect SARS-CoV-2, a single positive test result is considered enough evidence to diagnose COVID-19. Most tests are authorized for use on anyone aged 2 years and older. Check with your pediatrician or healthcare provider about which tests are recommended for children under age 2 or for persons who require assistance with performing self-testing.
