A Tuberculosis skin test looks for Tuberculosis infection. Tuberculosis proteins are injected under the surface of the skin. If a person is infected with Tuberculosis, a hard swelling (induration) will develop at the site of the injection in 48 to 72 hours. A health care professional must measure the size of the reaction and tell you if the test is
positive.
