Immunoglobulin E (IgE) is a type of antibody (immune protein) that has been linked to allergic reactions. It is usually found in trace amounts in the blood. To detect an allergy to a specific substance, this test measures the amount of allergen-specific IgE in the blood. IgE is an antibody that works as part of the body's immune system to protect it from "intruders."
