Uses For tuberculin. Tuberculin purified protein derivative (PPD) is used in a skin test to help diagnose tuberculosis (TB) infection in persons at increased risk of developing active disease. Tuberculin skin test is done by injecting tuberculin PPD into the surface layer of the skin. If the test is positive, a reaction will be seen at and around the place of injection or puncture. If the test is given using an injection, this reaction is usually a hard, raised area with clear margins.
Intradermal injection. Intradermal injection is the injection of a substance into the dermis, just below the epidermis. This route has the longest absorption time as compared to subcutaneous injections and intramuscular injections. As a result, it is used for sensitivity tests, like tuberculin and allergy tests, and for local anesthesia. Additionally, the body's reaction to substances is more easily visible since it is closer to the surface.
