    Dear Editor

    I thank Mishra and colleagues for their cogent comments about the potential clinical utility of ELISPOT for diagnosis of tuberculosis infection in high burden countries, such as India.[1]

    The high prevalence of latent tuberculosis infection in Indian adults [2] means that ELISPOT (as with any test of tuberculosis infection, as opposed to active disease) cannot be used to routinely ‘rule in’ a...

However, even then, it is surprising that there is only one study on Indian subjects.[2] Using this test, the authors recorded a 80% prevalence for latent tuberculosis in healthy adult Indians, compared t...
