Table 1. Sensitivity and specificity of the ICA by the ImmuneMed Leptospira IgM Duo Rapid test kit against MAT (gold standard).

Test by ICA		MAT positive	MAT negative	Total
ICA positive		68 (true positive)	10 (false positive)	78
ICA negative (intermediate result included)a		25 (false negative)	94 (true negative)	119
Total		93	104	197
	Diagnostic sensitivity (%)	73
	Diagnostic specificity (%)	90
	PPV (%)	87
	NPV (%)	79

ICA = immunochromatographic assay, MAT = microscopic agglutination test, PPV = positive predictive value, NPV = negative predictive value.

^aInterpretation of ImmuneMed ICA intermediate result: inconclusive and not positive.
