COVID-19 Self-Testing

Testing is an important tool to help reduce the spread of COVID-19. If you have symptoms or had a known exposure to someone with COVID-19, you should be tested, regardless of vaccination status. 

Testing can lead to quick identification of positive cases, help provide quick treatment and isolation for those infected, and help identify anyone exposed to the virus so they too can get treated quickly.

Covid-19 self-tests (also known as at-home tests or over-the-counter [OTC] tests) are one type of test to identify the virus that causes COVID-19. Self-testing offers fast results and can help protect you and others and reduce the chances of spreading COVID-19.

Understanding Your At-Home COVID-19 Test Result

If Your Test Result is Positive

A positive self-test result means that the test detected the SARS-CoV-2 virus and indicates that you very likely have a current infection. After receiving a positive at-home test result: 

  1. Stay Home and Isolate Immediately. Stay home for at least 5 days except to get medical care. Stay away from household members and do not have visitors to your home. Avoid public transportation. If, after 5 days, you still feel sick, continue to stay home until your symptoms resolve. Call your doctor for guidance. For more detailed information on isolating after you test positive, click here to read the CDC recommendations or use the CDC's quarantine and isolation calculator.
  2. Contact Your Healthcare Provider and Local Health Department.  Inform your healthcare provider of your positive test result. Contact them first by either phone or email. If you live in Norwalk, notify the Norwalk Health Department of your positive result by completing the Covid-19 Test Self-Reporting Portal at If you live in another town, please contact your local health department if you have questions.
  3. Inform Close Contacts About COVID-19 Exposure. After receiving a positive at-home test result, it is extremely important to inform those you have been in contact with in the two days before you started to feel sick and any time after taking your test. If you didn’t have any symptoms, notify those you had been in contact with two days before you took your test, and anytime after taking your test. This will allow the exposed individual time to have their own testing done, monitor for symptoms, and quarantine to minimize the chances of spreading COVID-19 on to more people.

If Your Test Result is Negative

A negative self-test result means that the test did not detect the virus and you may not have an infection, but it does not rule out infection. Repeating the test within a few days, with at least 24 hours between tests, will increase the confidence that you are not infected. Serial tests, defined as two or more tests over several days with at least 24 hours between tests, improves the reliability of self-testing and reduces your risk of transmitting COVID-19 to others.
