Maybe I’m wrong here, but weren’t you one of the Pro vax Freepers touting the legitimacy of the PCR test for COVID? That sure didn’t age well if that was you.
I defined what PCR is used for and said it’s a worthless screening test. The problem with PCR is you can have a non clinically significant positive. This is not a false positive. The other issue is that PCR is a highly specific test used to confirm a highly sensitive test. It was used incorrectly. But that is just having knowledge of Bayesian statistics.
