Tuberculin Skin Test Audio

 

Synonym(s): Purified Protein Derivative Test, Mantoux Tuberculin Skin Test

A screening test for tuberculosis (TB) performed by injecting a small amount of fluid (called tuberculin) just below the skin. A positive reaction 48 to 72 hours after the injection indicates that the person has been infected with TB bacteria. Additional tests are needed to determine whether the person has latent TB infection or TB disease. People with HIV infection or another medical problem that weakens the immune system should be tested for TB.
