Loop-mediated isothermal amplification (LAMP) is a newly developed molecular method that can be performed isothermally. We developed and evaluated a LAMP assay using novel primers to diagnose tuberculosis directly from clinical samples.Primers were designed to amplify the specific novel esat-6 gene target of Mycobacterium tuberculosis (MTB). Quantitated DNA was used to determine analytical sensitivity and specificity was evaluated by testing 29 NTM and 37 other bacterial species. After standardization, its sensitivity and specificity were evaluated on samples from 118 TB suspected and 31 non-TB patients and compared it with smear, culture and mPCR methods.LAMP was able to detect 5 fg DNA (one MTB) within 21 min and found to be 10 times more sensitive than mPCR and showed 100
