PCR testing and the viruses
I received an email yesterday asking some questions about the PCR test. Considering that visitors to the blog may also find my answers useful, I share my responses here.

Dear …:
Answers to your questions may be found in one of my blog articles (link). Please consider reading it. For further clarity, I am providing answers to the questions below as well (in red letterings). I hope you will find the answers helpful.
.
Q: “If a SARS-CoV-2 virus has not been isolated, when the PCR test comes back positive, what has it positively identified?”
The PCR does not test for viruses, i.e., it is not a test for viruses. A PCR test determines the presence of PRESUMED (imagined) RNA or DNA. Therefore, as the viruses have never been isolated, the authenticity of their association to a specific RNA/DNA cannot be established.
A positive PCR test shows the presence of some RNA/DNA from an unknown source. It could be from many sources, including sometimes claimed to be from healthy subjects. A positive PCR test (often considered as “case”) has no scientific meaning or relevancy to the virus/illness.
.
Q: “Is it an influenza virus or some other virus?”
Again, a PCR test is not a test for influenza or any other virus. It is RNA/DNA test without its established or confirmed link to a specific virus.
.
Q: “In addition, can the PCR test distinguish between viruses?”
Of course not. PCR test is not for viruses, so it cannot differentiate between viruses.
.
Q: These are the two questions I have not been able to locate an answer to, and I would be grateful if you could provide clarification.
The reason for the lack of answers is that the PCR test belongs to the science of (analytical) chemistry. However, it is conducted and interpreted by others without appropriate training and knowledge of the subject. Therefore the PCR testing, as it is conducted now (i.e., for diagnosis purposes), must immediately be stopped as being irrelevant.
