From Wikipedia, the free encyclopedia
COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2. The two main branches detect either the presence of the virus or of antibodies produced in response to infection.[1][2] Molecular tests for viral presence through its molecular components are used to diagnose individual cases and to allow public health authorities to trace and contain outbreaks.
Sensitivity and specificity
PCR-based test
RT-PCR is the most commonly-used diagnostic test.[171] It typically has high sensitivity and specificity in a laboratory setting: however, in one study sensitivity dropped to 66–88% clinically.[172]
Sensitivity is also a function of the number of PCR cycles, as well as time and temperature between sample collection and analysis.[175] A cycle threshold of 20 cycles would be adequate to detect SARS-Cov-2 in a highly infective person.[175] Cycle thresholds above 34 are increasingly likely to give false positives outside of high biosafety level facilities.[175]
On July 16, 2020, Dr. Anthony Fauci of the US CDC indicated that positive results obtained from RT-PCR tests run at more than 35 cycles were almost always "just dead nucleotides".[176] On August 29, 2020, the New York Times reported that, "In three sets of testing data that include cycle thresholds, compiled by officials in Massachusetts, New York and Nevada … most tests set the limit at 40 [cycles], a few at 37” and that the CDC was examining the use of cycle threshold measures “for policy decisions,”[177] On July 21, 2021, the CDC, in their "Real-Time RT-PCR Diagnostic Pan: Instructions for Use", indicated tests results should be determined at 40 cycles.[178]
There is nothing to be challenged here. An honest report by Wikieditors.
I will just add that the reports sent back to doctors do not give the number of cycles that were done.
Animals
In May 2021, Reuters reported that Dutch researchers at Wageningen University had shown that trained bees could detect the virus in infected samples in seconds and this could benefit countries where test facilities are in short supply.[164] A two-month study by the Necker-Cochin hospital Paris in conjunction with the French national veterinary school also found that dogs were more reliable than current lateral flow tests according to the Guardian.[165]
You can see the good dogs at work on YouTube. The trainers observe that state authorities are not interested. The problem with testing by dogs is that it is so rapid and efficient and cheap.
The behaviour of state authorities since January 2020 suggest that causing this virus to become extinct is not a shared objective.
Covid-19 testing by dogs is not a money maker, just like Vitamin D, HCQ, zinc, and ivermectin. Training dogs takes time and requires a competent trainer. Using dogs requires employing people, and there is not much money to be made that way. The objective of the pandemic managers is to enable corporate cronies to squeeze money out of the state and out of citizens and to spread fear, creating an obedient population, which will follow orders and accept an imitation of China's social credit system.
All malevolently stupid orders issued by Western regimes become rational, if we assume that the objective of the pandemic was regimentation, necessary for the safety of the oligarchy.
