Zusammenfassung:A whole blood assay is described to measure T cell mediated immune responses to leprosy and provide an alternative to the conventional lymphocyte transformation test. Optimal conditions were defined for the whole blood assay, and interferon-γ measurement was found to be a more sensitive way of measuring responses than tritiated thymidine incorporation. The assay was shown to be useful for investigating responses to a range of leprosy antigens. A whole blood assay has the advantages of being quick, simple and requiring only a small volume of blood, making it more appropriate as an immuno-epidemiological field test in leprosy endemic areas.
