			| Mantoux Tuberculin Skin TestSource: U.S. Centers for Disease Control and
		Prevention (CDC). http://www.cdc.gov During a Mantoux (PPD) tuberculin skin test, TB antigens are injected
		under the top layer of skin. A positive reaction, usually a firm red bump where
		the needle went into your skin, means you were exposed to TB bacteria. This
		test does not reveal whether you have active TB, which can be spread to others.
		A trained health professional must interpret your test.ByHealthwise StaffPrimary Medical ReviewerE. Gregory Thompson, MD - Internal Medicine
