There is a pretty exhaustive discussion on this in the UA forum.

While you are correct that the test itself is the same, not all of the BinaxNow tests can be used with emed’s telehealth monitored testing. Maybe something to do with the barcode? Not sure but just make sure you buy the correct test.
