Self-testing for COVID-19 can be done using an over-the-counter (OTC) rapid antigen test to find out if you have COVID-19 infection. An OTC test for COVID-19 can be taken anywhere, including your home, and will provide results within minutes.

The at-home test for COVID-19 allows you to see if you are COVID-19 positive or negative at the time of testing. It does not detect any previous infection or help you find out if you have immunity to COVID-19.
