Testing

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.

Every household in the U.S. is eligible to order 4 free at-home COVID-19 tests. Rapid antigen tests are also available for purchase at many pharmacies, retailers, community sites, and online stores. If you plan on using an at-home rapid antigen test, you should have several tests readily available so that you can test more than once. Since test quantities vary by manufacturer, check how many are included in a kit to ensure you have enough tests on hand.

COVID-19 PCR and rapid antigen tests are also administered at clinics, pharmacies, health centers,  community testing sites, or your doctor’s office. To find PCR and rapid antigen testing options near you, including free testing options, search the U.S. Health and Human Services “Test to Treat” testing web page or visit your local health department’s website.
