Spearman correlation between three immunoassays and cPass neutralization antibody. (A‐C). Abbott SARS‐CoV‐2 IgG II Quant (A), Roche Elecsys anti‐SARS‐CoV‐2 S (B), and DiaSorin LIAISON SARS‐CoV‐2 TrimericS IgG (C) demonstrated strong correlations with Genscript cPass surrogate virus neutralization test (Spearman's rho of 0.87, 0.87, and 0.88 for each). (D‐F). Three immunoassays demonstrated strong correlations with each other. Spearman's rho of 0.88 between Abbott SARS‐CoV‐2 IgG II Quant and Roche Elecsys anti‐SARS‐CoV‐2 (D); Spearman's rho of 0.9 between Abbott SARS‐CoV‐2 IgG II Quant and DiaSorin LIAISON SARS‐CoV‐2 TrimericS IgG (E); Spearman's rho of 0.85 between Roche Elecsys anti‐ SARS‐CoV‐2 and DiaSorin LIAISON SARS‐CoV‐2 TrimericS IgG (F)
