Another. Long article. Well sauced. Worth a read.

So to start, it is very remarkable that Kary Mullis himself, the inventor of the Polymerase Chain Reaction (PCR) technology, did not think alike. His invention got him the Nobel prize in chemistry in 1993.
Unfortunately, Mullis passed away last year at the age of 74, but there is no doubt that the biochemist regarded the PCR as inappropriate to detect a viral infection.
A third example is a study from Singapore in which tests were carried out almost daily on 18 patients and the majority went from “positive” to “negative” back to “positive” at least once, and up to five times in one patient.
Even Wang Chen, president of the Chinese Academy of Medical Sciences, conceded in February that the PCR tests are “only 30 to 50 per cent accurate”; while Sin Hang Lee from the Milford Molecular Diagnostics Laboratory sent a letter to the WHO’s coronavirus response team and to Anthony S. Fauci on March 22, 2020, saying that:
It has been widely reported in the social media that the RT-qPCR [Reverse Transcriptase quantitative PCR] test kits used to detect SARSCoV-2 RNA in human specimens are generating many false positive results and are not sensitive enough to detect some real positive cases.”
In other words, even if we theoretically assume that these PCR tests can really detect a viral infection, the tests would be practically worthless, and would only cause an unfounded scare among the “positive” people tested.
