In the USA, the authorization for RT-PCR tests ceases at the end of the year … those underlying the Green Pass. Too controversial technique

The CDC, Center for Disease Control USA, made an announcement a few days ago that either went unnoticed, or was underestimated. Let's read it :

Audience: Individuals who perform COVID-19ing tests

Level: Warning for diagnostic centers

After December 31, 2021, CDC will withdraw its application to the U.S. Food and Drug Administration (FDA) for the Emergency Use Authorization (EUA) of the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel , the test first introduced in February 2020 for the detection of SARS-CoV-2 only. CDC provides this notice in advance to clinical laboratories to allow sufficient time to select and implement one of the many FDA-cleared alternatives.

Visit the FDA website for a list of authorized COVID-19 diagnostic methods. For a summary of the performance of FDA-cleared molecular methods with an FDA reference panel, visit this page.

In preparation for this change, CDC recommends clinical laboratories and testing sites that have used the CDC 2019-nCoV RT-PCR assay to select and begin transitioning to another FDA-cleared COVID-19 assay. The CDC encourages laboratories to consider adopting a multiplex method that can facilitate the detection and differentiation of SARS-CoV-2 and influenza viruses. Such tests can facilitate the continuation of testing for both influenza and SARS-CoV-2 and can save time and resources as we head into the flu season. Laboratories and test sites must validate and verify the selected test within their facility before starting clinical trials.

The tests to be used instead of RT-PCR, according to the CDC; they are serological tests, or molecular tests.

Why is the test that until now was the basis of the Covid-19 diagnostics being abandoned? The New York Times told us, quite clearly since August 2020: an excessive number of amplification cycles of the RNA fragments can lead to the detection of the virus even where this is not there, or rather it is represented only by fragments non-viable RNA that they are unable to infect. Therefore the virus is detected even when it is not there, or in any case it does not develop in culture.

The CDC and the FDA are a kind of world encyclopedia of medical practices: a test that is not approved in the US usually loses its value even abroad. In Europe, on the other hand, the RT-PCR system is considered fundamental and irreplaceable. The "Green Pass" is issued on the basis of these texts, and so are the quarantines. With this move, these measures lose much of their scientific legitimacy. Will the authorities take this into account, or will they continue on their way even ignoring the decisions of important scientific authorities?
