PCR inventor did not design it to detect infectious diseases
PURPOSE
The purpose of this document is to illustrate how mainstream disinformative "fact-checkers" can convince you of a lie by telling you some true facts. At the same time, we will attempt to clarify the position of Dr. Mullis, the inventor of the PCR process, on the misuse of it for diagnostic purposes.
INTRODUCTION
The PCR technique or process - not the PCR test for diseases (1) - was invented by Dr. Kary B. Mullis, who received the Nobel Prize for his invention. He died in August 2019, before Covid-19 began to spread in December 2019, but he lived through a time in which PCR was promoted to "diagnose" some diseases (AIDS, in particular; also Pertussis, whose PCR test created a false epidemic in 2004-2006 (2)). He was very clear on his opposition to the use of PCR to diagnose AIDS (3).
For clarity:
• The PCR technique or process refers to the laboratory process designed by Dr. Mullis to "amplify" (i.e. create millions or billions of copies) of portions of genetic material (DNA o RNA), in order to better study the genetic material. (1)
• The concept of PCR tests for diseases refers to the use of the PCR process to design, for a given infectious disease, a PCR test that targets for a highly specific signature of DNA or RNA of the suspected infectious agent (e.g. a certain virus). This is based on the assumption that the detection of the infectious agent, in whatever amount it is found, equals, or "likely" proves, the disease. (4)
DETAILS
Did Dr. Mullis designed the PCR process to detect infectious diseases?
Some "fact-checkers" (5) have approached the issue as it were just about discarding some quotes allegedly said by Dr. Mullis. But discarding some quotes does not disprove the known position of Dr. Mullis (6) on the misinterpretation of the PCR technique for diagnostic purposes.
If you are asking whether Dr. Mullis said explicitly "My PCR test was not made to detect any type of infectious disease", the answer is no, he did not say that words. To begin with, he did not invented a test, he invented a technique (1), that others (not him) have converted into a test (more exactly, into a different and specific test for each alleged infectious agent of a disease).
The position of Dr. Mullis is very clear. He said:
“I think misuse PCR is not quite – I don’t think you can misuse PCR. The results, the interpretation of it, if they could find this virus in you at all, and with PCR, if you do it well, you can find almost anything in anybody. It starts making you believe in the sort of Buddhist notion that everything is contained in everything else. Right, I mean, because if you can amplify one single molecule up to something which you can really measure, which PCR can do, then there’s just very few molecules that you don’t have at least one single one of them in your body, okay. So that could be thought of as a misuse of it, just to claim that it’s meaningful.” (3)
It is obvious, from this quote, that Dr. Mullis is separating the proper use of PCR - to detect a signature of DNA or RNA in a sample - from the wrong interpretation - the interpretation that the presence of a single molecule (or a small or uncertain quantity of them) is a disease.
He is clearly ridiculing the notion that a PCR test can be used as the diagnostic of a disease.
Is it really necessary to have him say it more explicitly? After he had been so critical of the use of PCR to "diagnose" AIDS (3)? That would be the same as arguing that, because Jesus did not say the exact words "I think that wars are not a good idea", He was not in favor of Peace.
Said quote from Dr. Mullis - conveniently omitted by the "fact-checkers" (5) - should be enough to prove the point.
But there is more…
