This is not much discussed now with RAT tests available, but the PCR test for Covid has its dangers. As detailed below, the way it is generally used with a large number of cycles, generates false positives. The CDC said that the PCR test cannot distinguish between SARS-CoV-2 and the influenza virus.
Kary Mullis, the inventor of the PCR test, also denounced its use as an unreliable diagnostic tool. “If you can amplify one single molecule up to something that you can really measure, which PCR can do, then there’s just very few molecules that you don’t have. That could be thought of as a misuse of it, just to claim that it’s meaningful,” said Mullis. “It doesn’t tell you that you’re sick. It doesn’t tell you that the thing you ended up with really was going to hurt you or anything like that.”
