No, actually the standard swab & wait days for results tests, can have about a very significant false negative rate, particularly if administered early on.The standard Viaral Covid PCR tests are pretty accurate but the rapid test run between 15-20% false negative and unfortunately those are the tests that everyone will be using for screening.
There are many articles on the topic, but I can't link them, possibly because I'm new here. Look up "covid swab false negative" & check Science Daily, NY Mag, etc.
