Diagnostic significance of detecting neutralizing antibodies to SARS-CoV-2

Abstract

Coronavirus disease is an infectious disease caused by a recently discovered coronavirus called SARS-CoV-2. Coronavirus disease caused by the SARS-CoV-2 continues to be the world’s greatest global challenge, both in terms of searching for treatment and prevention methods, and developing new diagnostic directions. One of the new directions of serological diagnosis is the possibility of determining neutralizing antibodies to SARS-CoV-2. This is a fully automated highly sensitive test for detecting neutralizing antibo­dies to RBD domain in S1, which is performed by immunochemiluminescent analysis and allows the simultaneous detection of total neutralizing antibodies (IgM + IgG) that increases the sensitivity of testing because the order of IgM and IgG antibodies is individual.
