Distribution of peak RU across various groups of study participants. Variation in levels of (A) CLIA (NC specific) index. Peak RU for (B) Nucleocapsid, (C) Spike, and (D) RBD among study participants followed up in this study. Comparison of peak RU for (E) Spike (F) RBD and (G) Nucleocapsid between healthy (n = 3), IgG−/IgM− (n = 22), IgG+/IgM+ (n = 11), IgG+/IgM− (n=14), and convalescent (n = 22) groups. Variation in peak RU for (H) Spike, (I) RBD, and (J) Nucleocapsid, compared at day 0 (n = 11), day 7 (n = 11), and in convalescent (n = 22) group. Pink colored symbols indicate IgG−/IgM− individuals in convalescent group. Red colored symbols represent asymptomatic individuals. Pink colored symbols indicate IgG−/IgM− individuals in convalescent group. Statistical significance was calculated by Mann–Whitney U-test; *p < 0.05; **p < 0.01; and ***p < 0.001.
