Development of a whole blood assay to measure T cell responses to leprosy : a new tool for immuno-epidemiological field studies of leprosy immunity.
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-gamma 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.
