We've mentioned that the PCR test has its problems.
A Portuguese appeals court has ruled that PCR tests are unreliable and that it is unlawful to quarantine people based solely on a PCR test.
“if someone is tested by PCR as positive when a threshold of 35 cycles or higher is used (as is the rule in most laboratories in Europe and the US), the probability that said person is infected is less than 3%, and the probability that said result is a false positive is 97%.”
This is not new. Most US testing is based on a 40-cycle test; the reliability of the test at 40 cycles is questionable.
