An enzyme-linked immunosorbent assay (ELISA) for field diagnosis of visceral leishmaniasis

A simplified enzyme-linked immunosorbent assay (ELISA) was evaluated as a diagnostic test for visceral leishmaniasis in the field on 222 individuals with splenomegaly and 110 controls. The test was shown to have a sensitivity of 98.4% and specificity of 100% when compared with parasite identification by splenic aspiration. The data indicate that the ELISA is an accurate, safe, and economical alternative to splenic aspiration for the diagnosis of visceral leishmaniasis.
