Description: Caption:
Created in 1965, this photograph depicts a pneumatic, intradermal delivery system that had been outfitted with a bottle of tuberculin solution for injection, for the screening of tuberculosis. The image was captured during a skin testing project, which took place in Muskogee County, Georgia, and was staged in order to show that fluid remained on the nozzle, and the skin after having implemented this delivery system. The TST is now performed by injecting 0.1 ml of tuberculin purified protein derivative (PPD) into the inner surface of the forearm. The injection should be made with a tuberculin syringe, with the needle bevel facing upward. The TST is an intradermal injection. When placed correctly, the injection should produce a pale elevation of the skin (a wheal) 6 to 10 mm in diameter. See PHIL 6806, for a more modern approach to the administration of this PPD test.
