Development of an enzyme-linked immunosorbent assay for the detection of IgG-antibodies to the causative agent of COVID-19 in human serum (plasma).

A new original Russian test kit for the detection of IgG-antibodies to the causative agent of COVID-19 - coronavirus SARS-CoV-2 by the method of enzyme-linked immunosorbent assay (ELISA) on a solid-phase «ELISA-SARS-CoV-2-AT-G» has been developed. In comparative tests with similar test systems «Vitrotest® SARS-CoV-2 IgG» (Vitrotest, Ukraine) and «Anti-SARS-Cov-2 ELISA (IgG)» (EUROIMMUN AG, Germany) high diagnostic efficiency of the new test system was shown.
