What is PCR and how it should be used

This from Dr. Sam Bailey; PCR testing, what it is and how it should be used:

Short explanation of PCR testing

Not intended for asymptomatic detectionPCR threshold matter

PCR (Polymerase Chain Reaction) was invented by Dr. Kary Mullis, a biochemist who won the Nobel Prize for his invention. He maintained that it should not be used to diagnose any disease alone rather be used as a tool for symptomatic diagnosis.

Here is the video of him saying the above quote:

This requirement is echoed in the PCR test guidelines provided to the labs by the manufactures; for example:

    The Kary Mullis quote has been fact check a million times. First it was John Lauritsen summarizing Mullis’s views and second he never said any of those specific quotes. Here is the quote in question:

    “PCR is intended to identify substances qualitatively, but by its very nature is unsuited for estimating numbers. Although there is a common misimpression that the viral load tests actually count the number of viruses in the blood, these tests cannot detect free, infectious viruses at all; they can only detect proteins that are believed, in some cases wrongly, to be unique to HIV. The tests can detect genetic sequences of viruses, but not viruses themselves.”
