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.
PPD skin test. The PPD skin test is a method used to diagnose silent (latent) tuberculosis (TB) infection. PPD stands for purified protein derivative. You will need 2 visits to your doctor's office for this test. At the first visit, the health care provider will clean an area of your skin, usually the inside of your forearm. You will get a small shot (injection) that contains PPD. The needle is gently placed under the top layer of skin, causing a bump (welt) to form. This bump usually goes away in a few hours as the material is absorbed. After 48 to 72 hours, you must return to your provider's office.
