Montoux skin test is used to test infection by tuberculus bacteria. An intradermal injection is given and test result is seen from 48 to 72 hours. An induration for more than 10 mm indicates positive motaux test. It only indicates that there is recent infection by tuberculus bacteria. It does not denotes anything else. It is sometimes false negative is severe tuberculosis. It helps in diagnosis of the tuberculosis.
