Are false positives common with PCR tests? How would that even happen? Does anybody have any insight?

The PCR tests for RNA, not active, replicating viruses.

The theory is one may find detectable RNA fragments, without the person truly having an active infection (I.e. they’ve already recovered).

There is also just human error with sample handling, contamination, etc.
