Direct Agglutination Test and Enzyme Linked Immunosorbent Assay with Urine Samples for the Diagnosis of Visceral Leishmaniasis

Background: visceral leishmaniasis (vl) or kala azar is an infectious disease caused by various species of leishmaniaparasites. the aim of this study was to detect and compare the presence of anti-leishmania antibodies in the urine of visceralleishmaniasis patients using elisa and dat methods.methods: a total of 30 urine samples were collected from vl patients referred to shiraz (southeast of iran) hospitals.moreover 31 urine samples were collected from healthy individuals and patients with other diseases such as malaria,brucellosis, hydatidosis and cutaneous leishmaniasis. collected samples were examined to detect anti-leishmania antibodiesin urine, using elisa and dat.results: anti-leishmania antibody was detected in urine of 18 out of 30 (60%) vl patients by dat while elisa detectedanti-leishmania antibodies in urine of 28 out of 30 (93.3%) of vl cases. sensitivity and specificity of urine-based datwas 60% and 83.9%, respectively while sensitivity and specificity of urine-based elisa were 93.3% and 93.5%, correspondingly.conclusion: urine-based dat and elisa have a reasonable specificity and sensitivity in diagnosis of vl. accordingly,urine-based elisa might be a suitable alternative for serum based assays for diagnosis of vl.
