Two articles came out yesterday that, if true, show that the false negatives and false positives numbers from 2020 that I have been using are now out of date. My old numbers were posted Dec. 9th in the “Appendices” and showed low false negatives and false positives for the BinaxNOW tests.

Some people say the antigen tests are good for knowing when you’re not contagious any more, which is something that PCR tests cannot do reliably (many false positives).
Soon, I’ll have an update to our company policy. Here are the two articles:
