Summary: There is still a need for a simple, non-expensive, sensitive, and specific test for visceral leishmaniasis that can be used both for accurate diagnosis and to monitor treatment efficacy. The authors describe a new test that can circumvent most of the drawbacks of existing approaches. It detects six leishmanial proteins or biomarkers that are eliminated in the urine of patients with visceral leishmaniasis. An initial clinical validation demonstrated that the test has a sensitivity of ≥93% and specificity of 100%. This new and accurate monoclonal antibody-based multiplexed assay could be a useful resource to diagnose most clinical forms and/or the severity of the disease. The test is ready for upscaling and validation for clinical use.
