ABSTRACT:
A method for allergy testing is carried out by applying to the skin of a patient a thin, flexible strip of adhesive tape a portion of which carries on its adhesive side at least one group of closely spaced projecting lances carrying an allergen, so that the tape releasably adheres to the skin, pressing at least the lance-carrying portion against the skin to cause the lances to penetrate the skin to a depth less than the subcutaneous tissue thereby carrying the allergen into the skin, and maintaining contact between the allergen and the thus-traumatized skin cells, leaving the strip in place for a period of time sufficient for the patient's skin, if allergic to the allergen, to produce an allergic reaction; and removing the strip from the skin whereby the patient's allergy to the allergen may be determined by visual observation of the skin area penetrated by the lances.
