WHO: PCR Test Unreliable
December 21, 2020
FROM Kit Knightly At OffGuardian:
The World Health Organization released a guidance memo on December 14th, warning that high cycle thresholds on PCR tests will result in false positives.
While this information is accurate, it has also been available for months, so we must ask: why are they reporting it now? Is it to make it appear the vaccine works?
The “gold standard” Sars-Cov-2 tests are based on polymerase chain reaction (PCR). PCR works by taking nucleotides – tiny fragments of DNA or RNA – and replicating them until they become something large enough to identify. The replication is done in cycles, with each cycle doubling the amount of genetic material. The number of cycles it takes to produce something identifiable is known as the “cycle threshold” or “CT value”. The higher the CT value, the less likely you are to be detecting anything significant.
This new WHO memo states that using a high CT value to test for the presence of Sars-Cov-2 will result in false-positive results.
To quote their own words [our emphasis]:
Users of RT-PCR reagents should read the IFU carefully to determine if manual adjustment of the PCR positivity threshold is necessary to account for any background noise which may lead to a specimen with a high cycle threshold (Ct) value result being interpreted as a positive result.
They go on to explain [again, our emphasis]:
The design principle of RT-PCR means that for patients with high levels of circulating virus (viral load), relatively few cycles will be needed to detect virus and so the Ct value will be low. Conversely, when specimens return a high Ct value, it means that many cycles were required to detect virus. In some circumstances, the distinction between background noise and actual presence of the target virus is difficult to ascertain.
Of course, none of this is news to anyone who has been paying attention. That PCR tests were easily manipulated and potentially highly inaccurate has been one of the oft-repeated battle cries of those of us opposing the “pandemic” narrative, and the policies it’s being used to sell.
