The identification of those allergenic substances that may be responsible for producing or aggravating diseases such as asthma, allergic rhinitis, eczema, urticaria, anaphylaxis, and gastrointestinal reactions is frequently important for effective patient care. Most allergens trigger symptoms by reacting with specific IgE antibodies on mast cells and basophils in target tissues, resulting in the release of potent vascular and smooth muscle-reacting mediators such as histamine and leukotrienes, and generation of inflammation with infiltration by lymphocytes and eosinophils.
