'COVID19 PCR Tests are Scientifically Meaningless. Though the whole world relies on RT-PCR to “diagnose” Sars-Cov-2 infection, the science is clear: they are not fit for purpose'

“these PCR tests cannot detect free infectious viruses at all”

The reason for this is that PCR is extremely sensitive, which means it can detect even the smallest pieces of DNA or RNA — but it cannot determine where these particles came from. That has to be determined beforehand.
And because the PCR tests are calibrated for gene sequences (in this case RNA sequences because SARS-CoV-2 is believed to be a RNA virus), we have to know that these gene snippets are part of the looked-for virus. And to know that, correct isolation and purification of the presumed virus has to be executed.
Hence, we have asked the science teams of the relevant papers which are referred to in the context of SARS-CoV-2 for proof whether the electron-microscopic shots depicted in their in vitro experiments show purified viruses.
But not a single team could answer that question with “yes” — and NB., nobody said purification was not a necessary step. We only got answers like “No, we did not obtain an electron micrograph showing the degree of purification”.
