Short Communication: Evaluation of a New Rapid Diagnostic Test for Quality Assurance by Kala Azar Elimination Programme in Bangladesh

Table 1

Sensitivity and specificity of “Onsite Leishmania Ab Rapid Test” strips for diagnosis of VL in Bangladesh.

Patients and healthy controls	Onsite Leishmania Ab Rapid Test (RDT)^*χ		Total
	Positive	Negative
Kala azar confirmed cases	94	6	100
Healthy control from endemic area	4	47	51
Healthy control from nonendemic area	0	50	50

*Sensitivity = 94% (95% CI: 86.9–97.5); specificity = 96% (95% CI: 89.6–98.8); positive predictive value (PPV) = 95.9% (95% CI: 89.3–98.7); negative predictive value (NPV) = 94.2% (95% CI: 87.2–97.6).
^χSensitivity, specificity, PPV, NPV, and 95% CI of all were calculated by the Clinical Calculator One (http://faculty.vassar.edu/lowry/clin1.html).
