Rapid antigen tests that are self-administered are also known as “self-tests,” “at-home tests,” or “over-the-counter” testing kits. When used correctly, these rapid antigen tests are highly reliable, easily accessible, and provide fast results. COVID-19 rapid antigen tests provide rapid results, can be taken in any location, and can be administered by a healthcare provider or yourself. They are a critical tool in controlling the spread of COVID-19.
Taking a COVID-19 test is an important way to protect yourself and others against respiratory illnesses. According to the CDC, they are especially helpful when:
- Respiratory viruses are causing a lot of illness in your community.
- You or the people around you were recently exposed to a respiratory virus, are sick, or are recovering from sickness.
- You or the people around you have risk factors for severe illness.
While positive tests are accurate and reliable, a single at-home test cannot rule out infection. If you test negative for COVID-19 with an at-home test, FDA recommends 2 additional negative tests for individuals with symptoms, or 3 antigen tests for those without symptoms, performed 48 hours apart. Instead of (or in addition to) repeat at-home testing, a single PCR test can be used to confirm an at-home test result.
If you test positive for COVID-19, take steps to prevent the spread of the virus.
