Controversy Surrounding COVID PCR Test False-Positives

Half of the positive PCR test results from some labs may actually be false-positives—reference below.

This issue will fuel speculation that authorities on the political left are abusing PCR test flaws to justify lockdowns and to justify mail-in ballots that are easier to manipulate. The added fear in the public from the additional “cases” may make people more accepting of hastily tested vaccines, a potential boon for Big Pharma.

An assistant professor of epidemiology at Harvard Medical School, Michael Mina, explains in a Harvard Magazine article that the PCR test amplifies viral RNA to detectable levels.

However the test can also ”detect tiny fragments of viral RNA even after the patient has recovered.”

“the vast majority of PCR positive tests we currently collect in this country are actually finding people long after they have ceased to be infectious.”

This article at Sky News presents similar information from a study at Oxford. “they found the tests were able to detect traces of the virus’s genetic material for a much longer period than it remains infectious”

There is also the issue of the threshold or amount of detectable viral RNA required to cause a test to be classified as positive.

Dr Mobeen Syed in his recent video about the PCR test controversy expresses great disappointment that the US FDA has not set a standard threshold. The 5 minute segment also provides the basics about PCR tests. It includes statements from the FDA and CDC—spoiler alert, officials kicking the can down the road.

In this 2 minute clip the very admirable Dr Paul Marik, the Chief of Emergency Medicine at E. Virginia Med School hospital, presents and explains a graph of data comparing PCR test results with actual culture test results. The results are strikingly DIFFERENT! There are far more positive PCR tests, especially when the test was done more than 8 days after onset of symptoms.

It is Marik’s view that after day 8 or so the PCR test is most likely picking up debris from dead viruses.

Later in the video, Dr Marik and Dr Syed present a similar graph but with the cycle threshold clearly visible. Notice that there are NO positive culture tests above the threshold of 30, yet many labs use a much higher threshold of 40. This causes many more tests to be classified as positive, possibly false-positive.


In this clip Dr. Chris Martenson describes a study of one lab using the higher threshold of 40. If the lab used a threshold of 35, HALF of the people who were considered positive would have been negative.

In this one minute clip Martenson presents study data suggesting that after 34 cycles it was not possible to cultivate live virus.

An article from Oxford’s CEBM presents the following:

“This detection problem is ubiquitous for RNA viruses detection. SARS-CoV… viral RNA can be detected long after the disappearance of the infectious virus.”

A study at Sciencedirect reports, “Positive results with high cycle threshold values were only seen in healthcare workers.”

It is the view of Martenson and others that all PCR tests should include the number of cycles that were required to produce the positive result. If only 20 cycles were required for the positive, it would suggest a high viral load requiring prompt medical attention.

The CEO of a hospital in India says they switched to a lab that includes the cycle threshold. He goes on, “If the value is between 20 and 25, home isolation [with remote case monitoring] can be advised….Hospital admission is a must in cases where the value is less than 20.”

This issue is gaining some traction in mainstream media.

MSN reports, “Up to 90 percent of people tested for COVID-19 in Massachusetts, New York and Nevada in July carried barely any traces of the virus and it could be because today’s tests are ‘too sensitive’, experts say.”

The title of an article at the NY Times is, “Your Coronavirus Test Is Positive. Maybe It Shouldn’t Be.” It quotes Dr. Mina and others about the excessively high threshold of 40.

The labs have an obvious motive to set the threshold higher than necessary. Additional positive tests will result in additional follow-up test$.

Government officials have been very proactive in limiting access to hydroxychloroquine(HCQ), a well-known medication that quite a number of primary care doctors say caused a dramatic reduction in hospitalization of their patients. Some studies of HCQ reported only half the deaths in treated patients. Yet governmental officials allow the labs to use an inflated PCR test threshold.

Maybe the governmental officials like the results of excessively high PCR test threshold—lockdowns, fear, greater acceptance of a poorly tested vaccine.

Maybe they don’t like zinc plus hydroxychloroquine and ivermectin that some professors think are nearly a cure and are so good that there is not much need for a vaccine.

In this short clip Martenson questions the honesty of the UK health minister about accuracy of the PCR test. It includes a threat about cancelling Christmas if people don’t comply with government regulations.

The technical results of these studies are simply being wrapped in right-wing opinion and sold as a controversy, when in fact the “controversy” is simply a manufactured one by those delivering this opinion.

I don’t buy it.

And your response is wrapped in a left wing opinion dismissing the science you don’t grasp as right wing opinion in order for you to not “buy it.”

You don’t like the idea that positive Covid testing may be vastly overblown so you conveniently become disinterested in the science.

No need to engage with it if you can just dismiss it because it doesn’t fit your political view.

Characterizing it as a right wing opinion in order to justify your left wing opinion is just a tad unreflective.

Apparently you have now gone so far left that you think the NYT is “right wing.” Good for you.

Here is a NYT article claiming the same as the OP’s citation.


And here is more on the Nobel Prize-winning inventor of PCR (polymerase chain reaction), Kary Mullis being cited as to why PCR can’t be used to test for viruses.


And more here (although it looks like the same article as above it is an addition in a series of three.)

Pretty sure my nephew had it. What with having a positive result AND having symptoms.
 
I’m sorry to hear that. I hope he has fully recovered and is not a “long hauler.”

Did he have problems with positive tests even after he was feeling recovered?

“May be?” I don’t get all excited over every claim of “may be…” And don’t confuse skepticism with disinterest.
No need to engage with it if you…
To engage requires the ability to verify all the facts presented. When facts are introduced that I cannot verify, I do not just assume they must be right. So I am unable to engage. That is my fault for not being a virology expert. I’ll bet that a real virology expert could engage with you just fine.
