Afaik PCR remains terribly and wonderfully sensitive. Any positive that relies on a PCR cycle threshold can have false positives due to contamination and primer dimers, and false negatives due to bad prep. Ideally you’d need a positive in multiple wells, and retest any that were borderline or had a fraction of positive wells. But that’s probably not happening. Personally I’d be much more interested in getting an antibody test.
