La obstinación es quizá la única cualidad humana valiosa no sólo en la profesión policial sino al menos en todas las que tienen que ver con el concepto de verdad.

Alteration of COVID-19 PCR-tests due to lack of reliability

11 meses 5 días antes #1 por Editor
The Centers for Disease and Control Prevention (CDC) has alerted laboratories:

CDC recommends clinical laboratories and testing sites that have been using the CDC 2019-nCoV RT-PCR assay select and begin their transition to another FDA-authorized COVID-19 test. CDC encourages laboratories to consider adoption of a multiplexed method that can facilitate detection and differentiation of SARS-CoV-2 and influenza viruses. Such assays can facilitate continued testing for both influenza and SARS-CoV-2 and can save both time and resources as we head into influenza season. Laboratories and testing sites should validate and verify their selected assay within their facility before beginning clinical testing.

The PCR-tests were criticized already by the end of 2020.

The published RT-qPCR protocol for detection and diagnostics of 2019-nCoV and the manuscript suffer from numerous technical and scientific errors, including insufficient primer design, a problematic and insufficient RT-qPCR protocol, and the absence of an accurate test validation. Neither the presented test nor the manuscript itself fulfils the requirements for an acceptable scientific publication. Further, serious conflicts of interest of the authors are not mentioned. Finally, the very short timescale between submission and acceptance of the publication (24 hours) signifies that a systematic peer review process was either not performed here, or of problematic poor quality.  We provide compelling evidence of several scientific inadequacies, errors and flaws.–-CORMAN-DROSTEN-REVIEW-REPORT.pdf
