Added information on when and why to use a self-test. Self-testing is one of several risk-reduction strategies to reduce the chances of COVID-19 transmission. They may be used regardless of vaccination or symptom status.
Key Points
- COVID-19 self-tests (also referred to as home tests or over-the-counter (OTC) tests) are one of many risk-reduction measures, along with vaccination, masking, and physical distancing, that protect you and others by reducing the chances of spreading SARS-CoV-2, the virus that causes COVID-19.
- Self-tests can be taken at home or anywhere, are easy to use, and produce rapid results.
- You can use self-tests, regardless of vaccination status, or whether or not you have symptoms.
- Follow all of the manufacturer’s instructions for performing the test.
- If you test positive, you should isolate and inform your healthcare provider, as well as any close contacts.
- Consider using a self-test before joining indoor gatherings with others who are not in your household.
- A positive self-test result means that the test detected the virus, and you are very likely to have an infection and should stay home or isolate for 10 days, wear a mask if you could have contact with others, and avoid indoor gatherings to reduce the risk of spreading disease to someone else.
- 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.
