For doing rapid COVID-19 tests anywhere
What is a Self-Test or At-Home Test?
Self-tests for COVID-19 give rapid results and can be taken anywhere, regardless of your vaccination status or whether or not you have symptoms.
- They detect current infection and are sometimes also called “home tests,” “at-home tests,” or “over-the-counter (OTC) tests.”
- They give your result in a few minutes and are different from laboratory-based tests that may take days to return your result.
- Self-tests along with vaccination, wearing a well-fitted mask, and physical distancing, help protect you and others by reducing the chances of spreading COVID-19.
- Self-tests do not detect antibodies which would suggest a previous infection and they do not measure your level of immunity.

What Your Test Results Mean
Positive
- The test detected the virus and you have an infection.
- Stay home for at least 5 days and isolate from others in your home.
- Tell your close contacts.
- Wear a well-fitted mask when around others. If available, a N95 or KN95 respirator is recommended.
- Watch for symptoms. If you have any emergency warning signs, seek emergency care immediately.
- Tell your healthcare provider. Contact them as soon as possible if:
- Your symptoms get worse.
- You are more likely to get very sick because you are an older adult or have an underlying medical condition. Possible treatment may be available for you.
- You have questions about your isolation.
Negative
- The test did not detect the virus, but doesn’t rule out an infection.
- Some self-tests are designed to be used in a series (also known as serial testing). Consider repeating the test 24 to 48 hours later. Multiple negative tests increases the confidence that you are not infected with the virus that causes COVID-19.
If you think your test result may be incorrect, contact the test manufacturer for assistance, consider taking another at-home test, or contact a healthcare provider for help.
