Hmmm. Using data from testing at work...Study in Ct a while back put the PCR tests at a 30% false pos rate.....
Within the last 30 days:
31,596 tests, 12 positive (0.038%)
So, assuming that we have nothing but false positives here (no one actually has it) that is still one heck of a PCR test at 99.972% accurate.
If some of those results are legitimate positive results then the test has to be better than 99.972% accurate.
Unless, of course, it has a false negative rate that is through the roof.
I have yet to find any actual data about sensitivity or specificity for any of the tests that are being used out there. It is just positive/negative and assumed to be 100% accurate.
