Recent laboratory advances in diagnostics and monitoring response to treatment in leprosy.

The present review briefly summarizes the highlights of the recent advances in -specific tests for early diagnosis of leprosy. In addition to establishing the diagnosis of clinical cases of leprosy, these tests have also been used to detect subclinical infections in endemic population. Several attempts have been made from 1980 onward for standardization of specific diagnostic assays for early detection of leprosy. Brief account about the development and use of these assays has been described in this review article.
