Evaluation of Serological Techniques for Screening for COVID-19 Infection at the University Hospital of Rouen

Overview

At present, the offer of tests for the serological diagnosis of CoVID-19 (detection of IgG, IgM or IgA antibodies against CoV-2 SARS) is plethoric and is based on the use of a very large number of rapid diagnostic unit tests, a few dedicated high throughput automated systems or reagents on existing open systems. The offer will continue to expand in the coming months. In order to meet the objectives mentioned by the Prime Minister, and confirmed in the HAS report of April 16, 2020 and in the opinion n°6 of the COVID-19 scientific council concerning the potential use of these serological tests at the end of the COVID-19 epidemic, the Virology laboratory wishes to validate the sensitivity and specificity of the tests it intends to use.
