immunoglobulin E (IgE),

one of the five classes of antibodies produced by the body. It is concentrated in the lungs, skin, and mucous membranes. It provides the primary defense against environmental antigens and is believed to be responsive to immunoglobulin A. IgE reacts with certain antigens to trigger the release of chemical mediators that cause anaphylactic hypersensitivity reactions characterized by wheal and flare. The normal concentration of IgE in serum is 0.01 to 0.04 mg/dL. Compare immunoglobulin A, immunoglobulin D, immunoglobulin G, immunoglobulin M.
