The performance of b-EDIII-T as a capture antigen in the detection of anti-DENV antibodies^a

	IgG (n = 80)			IgM (n = 81)
Parameter	PS	SA	Mean Ratio of S/Co values (95% CI)b	PS	SA	Mean Ratio of S/Co values (95% CI)b

^aAssays were done using polystyrene (PS) microtiter wells or streptavidin (SA) coated microtiter wells. The number of sera analyzed is denoted by n.

^bThis column represents the mean ratio of S/Co values using SA plates to S/Co values using PS plates; the cut-off values were 0.31 and 0.28 for PS and SA, respectively, in the IgG assay, and 0.23 and 0.25, respectively, in the IgM assay. The 95% confidence interval is indicated in parentheses.

^cPercent Sensitivity = (Number of sera that scored positive by our test/Number of sera that scored positive using PanBio ELISAs) × 100

^dPercent Specificity = (Number of sera that scored negative by our test/Number of sera that scored negative using PanBio ELISAs) × 100
