SARS-CoV-2 neutralizing antibodies (nAbs) are special antibodies that function to prevent SARS CoV-2 from binding to the ACE2 receptor of human cells. High levels of nAbs indicate immunity against COVID-19. Standard IgG/IgM antibody tests – which are universally available – do not detect for nAbs and can only provide an indirect indication for immunity.
A SARS-CoV-2 nAb test can be used to monitor immunization against COVID-19, evaluate vaccine efficacy across vaccinated patients, and assess recovering patients.
