Sensitivity, specificity, percent agreement, and kappa value for InBios DENV detect IgM capture ELISA compared to the in-house MAC-ELISA

Result by InBios DENV Detect IgM capture ELISA (n = 79)b	No. of samples with result by in-house MAC-ELISAc			% (95% CI)			Kappa value
	Positive	Negative	Presumptive positive	Sensitivity	Specificity	Agreement
Positive	22	2	0
Negative	0	50	0
Equivocala	2	1	2
Total	24	53	2	92 (73–99)	94 (84–99)	94 (86–98)	0.87

^aEquivocal samples were considered false negative for sensitivity and false positive for specificity.

^bInBios IgM positive, ISR of >2.84; InBios IgM equivocal, ISR of 1.65 to 2.84; InBios IgM negative, ISR of <1.65.

^cMAC-ELISA positive, P/N of ≥3; MAC-ELISA presumptive positive, P/N of ≥2 and <3; MAC-ELISA negative, P/N of <2.
