Pcr tests are designed to have the error rates to the false positive side of the equation. The reason is from a epidemiological Point of view it is better to have people identified and quarantined as positive to an outbreak which then can be retested repeatedly and let out of quarantine if truly false. Than to have a false negative and that person not be quarantined and be spreading the contagion. This is common and solid epidemiological practice. Nearly EVERY pcr test is designed exactly this way. False positives are the desired outcome vs false negatives better to inconvenience someone for a few days while the sample is retested then to let them spread the pathogen as a false negative. Anyone who studies science should know this already.
A reasonable number of false positives, sure.
But I've heard that they've made these PCR tests way too sensitive and that there are way too many false positives.
