Here’s one of the dangers of relaxing regulations too far...antibody testing is not very accurate, yet. Buyer beware on tests with 15% false positives being used for anything meaningful. At some point, the FDA will need to reign these cowboy non-EUA tests in and pull some off the market.

qPCR tests, while way more sensitive, aren’t as suspect in this process. There are probably some junkier tests out there, but since it is a yes/no decision, it’s really just limit of detection. I havent looked at any of the recent IFU’s for PCR tests and their data , but they’ll probably all fall in that <2% rate for both specificity and sensitivity.
