Testing Method - Additional Info
a) Wantai Ig total ELISA, (b) Wantai IgM ELISA, (c) Euroimmun IgG ELISA, (d) Euroimmun IgA ELISA, (e) DiaSorin Liaison XL IgG chemiluminescence immunoassay, (f) Cellex IgM/IgG, (g) InTec IgM/IgG, (h) Orient gene/Healgen IgM/IgG compared to an in-house plaque-reduction neutralization test (PRNT50) used as a reference
Reported Performance
Specificity: 99% (Wantai Ig tot), 99% (Wantai IgM), 99% (Euroimmun IgG), 94% (Euroimmun IgA), 90% (Liaison), 99% (Cellex), 85% (Intec), 88% (Orient/Healgen); Sensitivity: 99% (Wantai Ig tot), 90% (Wantai IgM), 81% (Euroimmun IgG), 97% (Euroimmun IgA), 81% (Liaison), 89% (Cellex), 90% (Intec), 100% (Orient/Healgen). Remark: Wantai ELISA detecting total Ig has the best overall characteristics to detect functional antibodies in different stages and severity of disease
