Which ones in your understanding are most likely to cause falso positives?
PCR my guess overall; easiest to inflate signal; but each test would have it’s own intrinsic false +/- rate. A monoclonal antibody test would probably give a cleaner signal than a polyclonal antibody test, but give more false negatives; this is a pre-caffeinated from the hip generalization.
Also, do you know which tests are most commonly used? No. Probably by state, hospital system, testing center wholesaler, Rx chain doing testing, etc.
Thanks for answer.
