Fig. 2. Correlations between antibody results by SARS-CoV-2 binding assays (three CLIAs, three EIAs, and one LFIA) and the neutralizing antibody results by sVNT. (A) Correlation between index values of SARS-CoV-2 IgG (Abbott; ratio, Siemens; index, Roche; log COI, Boditech; COI) and neutralizing antibody results (%) measured in 139 samples plotted according to disease severity. (B) Correlation between index values of SARS-CoV-2 IgG (Euroimmun; ratio, Vircell; index) or total antibody binding assays (BioRad; ratio) and neutralizing antibody results (%) measured in 109 samples plotted according to disease severity. The dotted line represents the assay cutoff for positivity. *P<0.001.
Abbreviations: COI, cut-off index; r, Pearson correlation coefficient.
