Reply to comment by kbotc in How soon after exposure is the flu contagious? by AcJc_0604

Does the protein BinaxNOW tests for differ from what Flowflex tests for? I don't trust BinaxNOW because I've never gotten a positive on them despite having had Covid twice now as confirmed by several days in a row of positive Flowflex tests. If they test for different proteins then that would explain it...

They test for the same protein.

I’m hesitant to recommend the Flowflex just because they had a massive counterfeit problem: https://www.fda.gov/medical-devices/coronavirus-covid-19-and-medical-devices/counterfeit-home-otc-covid-19-diagnostic-tests#diagnostic
