Mycobacterium tuberculosis or MTB is the causative agent of the deadly disease tuberculosis. This bacterium contains the mycolic acid and spreads tuberculosis through its cell covering. The MTB Detection test is a diagnostic test that examines the presence of this bacterium via nucleic acid amplification test (NAAT). This test was developed in the US and sponsored by the WHO for countries suffering from TB epidemic. Its main purpose is to detect tuberculosis and its stage so as to initiate the proper treatment at the right time. The test is a painless procedure and provides the results in usually 2 hours.
