A skin-testing system for in vivo intracutaneous use which comprises a novel injection unit and multiple applicator means, each of the units carrying biological or chemical substances for skin-testing, at least one of the units carrying a plurality of different antigens in admixture. Test substances are deposited intracutaneously by piercing the skin with each injection to predetermined depth; and the pierced skin is observed for response to the various substances and dermographia. The preferred applicator means comprises points carrying groups of admixed allergens selected from tree allergens, mold allergens, grass allergens, ragweed allergens, weed allergens, dust, epidermals and foods together with histamine control, and diluent control. Each of the injection units (20) includes a handle portion (25), hilt portion (22) and a scarifier portion (32) having means for carrying testing substances. A base member (10, 110) is provided with a plurality of recessed depressions (12, 112) adapted to receive and hold the injection units individually, with the scarifier portion or needle-like prong being received by a well portion (14, 114) containing antigens or the like. In a preferred embodiment each of the depressions is provided with vent means (116) for permitting gas escape. |
