There are only a few methods of testing for COVID-19
By Symptoms Only
For first 2 months this was all there was. The presentation of seasonal flu was what brought the world to a halt.
Blood Test - looking for antibodies
Before - the presence of antibodies in the blood could mean that the person had just recovered from some health challenge and their immune system had created antibodies which was evidence of their recovery.
Now - the presence of antibodies in the blood means that this patient is afflicted with a pathogen which is potentially fatal and is in need of some heroic treatment. So, this is the way the antibody testing for COVID-19 was conducted. There was no differentiation for viruses or bacteria or anything. It was a positive test for COVID-19. Any kind of unidentifiable viral or other debris in the blood was also counted as a positive test.
Polymerase Chain Reaction Test (PCR)
This was originally done by sending in a sputum sample. It's a completely unverifiable test.
More on PCR below.
These were only sent out by the Centre for Disease Control (CDC) about mid March to hundreds of hospitals and clinics across the U.S. supposedly to screen people for COVID-19. The problem is that the CDC's website states that it is "for experimental use only, NOT for diagnostic purposes." Then it goes on to state that "the CDC is making no claims for their validity."
So, after the kits went out to all the hospitals and clinics that's when there was a huge spike in numbers because a lot more positive tests could be reported as samples did not have to be sent in anymore.
On-site Test Kits
Most recently introduced supposedly claiming to be able to take a sample from a patient and to screen them for COVID-19 in 5-10 minutes.
This is completely ludicrous. It is impossible and scientifically untenable. These do not work at all. No-one claims that this can differentiate anything let alone COVID-19. They are completely unapproved and untested. And yet, the positive results from these unreliable tests are being included in the running total of COVID-19 cases being reported every day on the news.
These are the only tests driving the daily numbers.
The fact is, that none of these tests are scientifically verifiable and reproducible as a valid differentiation for COVID-19 specifically. They are all flawed.
This was invented by Dr Kary Mullis in the early 1980s. He won the Nobel prize for inventing this test. This test is touted by the medical profession then and now for diagnosing microbial disease in patients. They claim that it can specifically differentiate any viral disease from any other viral disease by sequencing the RNA and DNA. This claim is constantly made even today and is completely insupportable and untrue. No-one was more critical of the PCR test than its inventor Dr Mullis. It was disavowed from the very beginning.
Here is his quote.
"Quantitative PCR is an oxymoron. PCR, by its very nature is unsuited for estimating numbers...
a common misimpression that the viral-load tests actually count the number of viruses in the blood...
these tests cannot detect free, infectious viruses at all; they can only detect proteins that are believed, in some cases wrongly, to be unique to HIV.
The tests can detect particles of viruses, but not viruses themselves."
He was embarrassed and exasperated for decades about the claims that organised medicine was making for his test. It simply does not do what they claim. Amazingly no improvements have been made on this test in 40 years.
So, where is the science???
Yet this is the pitch used by doctors, hospitals, everyday media, medical literature, TV news and bureaucrats. It is the epitome of junk science.
This is how the PCR test works.
DNA helix is cleaved. A section of one of the strands is taken and it is doubled exponentially.
So something tiny becomes visible and supposedly measurable.
Coronavirus is RNA like all viruses, so that is converted to DNA by reverse transcriptase: RT-PCR.
Each doubling is called a cycle. The test counts how many cycles until RNA is detected, and how many before it disappears.
So the range of numbers is all that the PCR test really does.
"The coronavirus test is based on PCR, a manufacturing technique. When used as a test it does not produce a positive/negative result, but simply the number of cycles required to detect genetic material."
No new virus was ever purified (isolated and sequenced) by the Wuhan scientists. And the same is true in America. No novel virus for COVID-19 has ever been purified by any scientist in the US either.
It's all theoretical. "All they found were RNA fragments, presumed to be novel (they are unsequenced). There is no connection between the test and the particles, and no proof that the particles are viral."
"The only way...is to have a gold standard for presence of the virus, which can only be purification and characterization....this has never been accomplished..."for COVID-19
Doctors in Marseilles, France reported testing 4,084 samples for the novel coronavirus, using several systems approved for use in Europe, without a single positive...
Tests for infections are usually reported as either positive or negative.
In reality even individual tests are not binary, not positive or negative, but a range of numbers that are arbitrarily divided into positive and negative.
Other factors, including the bias of the doctor or laboratory, enter into the interpretation...
That's it. The PCR test is merely a best guess of the quantity of RNA in a sample. It doesn't sequence, isolate or purify any viruses.
It's common for most hospital patients to switch back and forth - positive to negative the next day - always switching back and forth.
Yet that's impossible: if you are infected how can you be uninfected the next day?
The PCR test:
Doesn't isolate and identify viruses
Doesn't provide RNA sequences of pathogens
Offers no baseline for comparison with patient samples
Cannot determine an infected from non-infected sample
"The coronavirus panic is just that, an irrational panic, based on an unproven RNA test, that has never been connected to a virus and which won't be connected to a virus unless the virus is purified. There is very little science happening."
You will never here any of this in the media.
Best kept secret:
Details of how test kits are supposed to work
Forbidden topic of discussion - corporate media
Emergency Use Authorizations (EUA) from FDA allow use of all unproven experimental test kits - "there's no time to see if they work"
