Feel good about the 4 government Rapid Tests you can order?! You're going to need a lot more for your family gatherings or corporate events....

New FDA Guidance (Aug 11, 2022) makes it clear that “rapid, lateral-flow antigen tests” (i.e.. “at home” tests) critically underperform when not used serially. To gain more certainty, one would need to test 3-times, 48 hrs apart – by then it is often too late for family gatherings and corporate events, etc. – and the cost of 3 tests approaches or exceeds the cost of better commercial testing.
