Prior to Xmas, “your local epidemiologist” stated that the antigen tests were ~50% accurate for asymptomatic cases. I believe she included a link to a study. There are a few people that i follow on Twitter that work in the testing programs in the film studio industry. In November, Erin Bromage, one of those people, stated that flowflex and binaxnow provided the best results for initial infection detecting, which are verified with pcr/molecular test.
