Abstract
An allergy testing method and apparatus for testing a patient for a plurality of allergies at substantially the same time, comprises a carrier for receiving a plurality of allergen applying devices, each allergen applying device including a source of an allergen and a movable pricking needle which is movable from an inactive position out of contact with the skin of a patient to an active position for pricking the skin of a patient and applying its associated allergen to the pricked skin when moved from the inactive position to the active position. The carrier holds and supports the plurality of allergen applying devices with a given spacing between each of the pricking needles, and an actuator is coupled to the carrier for moving the pricking needles from their inactive positions to their active positions to prick or pierce the skin of a patient and to thereby apply a respective allergen to the skin of the patient via the pricking needles.
