Anecdotally, many people I know who used an antigen (rapid) test have experienced false negatives. PCR appears to be the only way a positive COVID result is found.
It seems odd that the CDC updated this new recommendation and explicitly called out an antigen test is what one should use after the 5 day period of isolation.
