Article Abstract

The performances of two rapid tests and a standard serological test for the diagnosis of visceral leishmaniasis (VL) were compared using sera from 193 patients with VL and 85 controls. The Kala-Azar Detect(®), IT-LEISH(®) and IFI-LH(®) assays showed sensitivities of 88.1%, 93.3% and 88.6%, respectively, and specificities of 90.6%, 96.5% and 80%, respectively. The sensitivity values were similar for both rapid tests, but the specificity and positive predictive values of IT-LEISH(®) were higher than the corresponding values for IFI-LH(®). Both rapid tests showed satisfactory performances and can be used in primary health care settings; however, IT-LEISH(®) permits the use of whole blood, making this assay more suitable for bedside diagnosis.
