An allergy is an abnormal reaction to an ordinarily harmless substance called an allergen. When an allergen (such as pollen) is absorbed into the body of an allergic individual that individual’s immune system views the allergen as an invader and a chain reaction is initiated. White blood cells of the immune system produce immune globulin E (IgE) antibodies. These antibodies attach themselves to special mast cells causing a release of potent chemicals such as histamine. Allergic or hypersensitivity disorders may be manifested by generalized systemic reactions in any organ system of the body. The reactions may be acute, sub-acute or chronic, immediate or delayed, and may be caused by an endless variety of fur, venoms, foods, drugs, etc. The ideal management of the allergic individual is to identify the offending agent by various means of testing.
