PCR Tests Antigen Tests
Antigen tests* are rapid tests that usually produce results in 15-30 minutes. Positive results are very accurate and reliable. However, in general, antigen tests are less likely to detect the virus than PCR tests, especially when symptoms are not present. Therefore, a single negative antigen test cannot rule out infection. To be confident you do not have COVID-19, FDA recommends 2 negative antigen tests for individuals with symptoms or 3 antigen tests for those without symptoms, performed 48 hours apart. A single PCR test can be used to confirm an antigen test result. *Self-tests, or at-home tests, are antigen tests that can be taken anywhere without having to go to a specific testing site. Read self-test package inserts thoroughly and follow the instructions closely when performing the test. Read more: Self-Testing At Home or Anywhere

Positive
If Your COVID-19 Test Is
Negative
A negative COVID-19 test means the test did not detect the virus, but this doesn’t rule out that you could have an infection. If you used an antigen test, follow FDA recommendations for repeat testing. •If you have symptoms: •You may have COVID-19 but tested before the virus was detectable. •Consider that you may have another viral infection or illness that you need to get tested for. For many diseases, including flu, early diagnosis and prompt treatment is very important for preventing severe illness. •Take everyday preventive actions to prevent spreading an illness to others. •Contact a healthcare provider if you have any questions about your test result or if your symptoms worsen. •If you do not have symptoms but were exposed to the virus that causes COVID-19, you should continue to take recommended steps after exposure. •If you do not have symptoms and have not been exposed to the virus that causes COVID-19, you may return to normal activities. •Continue to take steps to protect yourself and others, including monitoring for symptoms. Get tested again if symptoms appear.
Antibody tests detect antibodies that your body makes to fight the virus that causes COVID-19. Antibody tests should never be used to diagnose a current infection with the virus that causes COVID-19. An antibody test may not show if you have a current infection, because it can take 1 to 3 weeks after the infection for your body to make antibodies. Antibody tests can be used for public health surveillance or to test for conditions associated with COVID-19.
