Allergy testing apparatus and method

An allergy testing apparatus for testing a patient for a plurality of substances, comprising:

• a rotatable, drum-like member;
• a plurality of spaced apart pricking or piercing means coupled to said drum member and extending substantially radially of said drum member and being spaced apart relative to each other over a circumferential portion of said drum member;
• resilient means over said pricking or piercing means for at least partially covering said piercing or pricking means;
• substance containing means mounted over said resilient means and including a plurality of substance sources spaced from each other and in registration with respective pricking or piercing means;
• and
• operating means coupled to said rotatable drum-like member for applying said rotatable drum-like member against the skin of a patient and for pressing said rotatable drum-like member in the direction of said skin of said patient to compress said resilient layer to thereby cause said pricking or piercing means to extend through said resilient layer and to pass through said respective substance sources so as to contact a respective substance and to then pierce or prick the skin of a patient, thereby applying the substance in registration with the respective pricking or piercing means to the skin of a patient, and for rolling said drum-like member along the skin of a patient to sequentially apply substances to the skin of the patient at spaced apart locations on the skin of the patient by respective pricking or piercing means, as said drum-like member is rolled along the skin of the patient.
