I'm not a subject matter expert on COVID-19 but I volunteered to be our program manager for testing and wrote our work statement for our testing contract that was recently awarded. I've talked to a lot of doctors, pharmacists, and health care providers the past 6 weeks.

The tests have to receive FDA emergency use authorization. I found this site which shows the COVID-19 tests that are authorized, https://www.centerforhealthsecurity.org/...Molecular-Tests

Some of the tests also will detect certain type of influenza.
