This is from a Lab Owner who knows his stuff. Initially he thought those who said NO virus has ever been purified were lying and or crazy. He has since apologized to the likes of Dr Andrew Kaufman and Jon Rappaport . Somewhat technical but very important explanation of the whole Damn Scamdemic !
…………………

“Since no quantified virus isolates of the 2019-nCoV were available for CDC use at the time the test was developed and this study conducted, assays designed for detection of the 2019-nCoV RNA were tested with characterized stocks of in vitro transcribed full length RNA … spiked into a diluent consisting of a suspension of human A549 cells and viral transport medium (VTM) to mimic clinical specimen.

In other words, they faked the covid virus by using gene bank cells which were deliberately and falsely labeled “covid.” This is how the PCR test was developed. The FDA admits it all. The PCR test is a fraud”
…………………..

Point #3: If you don’t have a CRM isolate, you can’t calibrate instruments against a known sample. And this means the PCR tests aren’t being calibrated against anything real and physical. Instead, they’re relying on downloaded digital libraries provided by none of than the CDC, the very same Big Pharma front group that’s spearheading this covid scam.”
…………………..
Point #4: PCR instruments are incapable of quantitative analysis. The “positive” hits are nothing but amplified background noise
