COVID-19 At-Home Rapid Tests have not been FDA cleared or approved; however, the FDA has authorized their use under an emergency use authorization. COVID-19 At-Home Rapid Tests are authorized only for the detection of proteins from SARS-CoV-2, not for any other viruses or pathogens, and are only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of COVID-19 under Section 564(b)(1) of the Federal Food, Drug and Cosmetic Act, 21 U.S.C. §360bbb 3(b)(1), unless the declaration is terminated or authorization is revoked soon. For serial testing, COVID-19 At-Home Rapid Tests should be performed twice over 3 days, at least 24 hours (and no more than 48 hours) apart. For symptomatic use, a single test can be used.
