The rapid detection of parasitic antigens in body fluid including urine by immunological tests such as
KAtex has been a valuable addition to clinical medicine. Existing method of microscopic bone-marrow
examination and immunological test for antigen –enzyme-linked immunosorbent assay (ELISA) test for
visceral leishmaniasis antigen are difficult to perform in the field, and this has limited use in rural areas of
endemic countries like Nepal. In this study we have tested 276 urine samples from visceral leishmaniasis
patients from different endemic areas of Nepal. Sixty-seven patients (24.3%) were found KAtex positive.
The clinical picture of these patients was compared with the KAtex test and additional laboratory findings,
knowledge, attitude and behaviour were assessed. High rate of KAtex positive (97.4%) was found in bone
marrow confirmed patients with high degrees of sensitivity and specificity. Hence the study confirmed that
the KAtex test is suitable for the confirmation of suspected cases in the field and hospital where bonemarrow
facilities are limited or where there is a lack of trained manpower as well as microscopic diagnosis
is not available.
