CDRH Office of In Vitro Diagnostics and Radiologic Health director **Timothy Stenzel** says that as of 2/17 FDA had authorized 331 tests and sample collection devices, including 247 molecular tests and sample collection devices, 70 antibody tests, and 14 antigen tests. Speaking at the 43rd CDRH [virtual town hall](http://www.fda.gov/media/146226/download?ref=fdaweb.com) to answer technical questions about the development and validation of SARS-CoV-2 tests during the public health emergency, Stenzel said there are 37 molecular authorizations that can be used for home collection samples. And there’s one molecular prescription at-home test, one antigen prescription at-home test, and one over-the-counter at-home antigen test.

He said that the virtual town halls will continue as long as test developers find them useful.
