Immunoglobulin E (IgE) and Allergies
Immunoglobulins E (IgE) are allergy antibodies produced by your body's immune system. IgE is one of several immunoglobulin classes (such as IgA, IgG, and IgM). Each immunoglobulin class contains many different and unique antibodies.
- IgE levels are generally elevated in people with allergic diseases (and asthma), but many of these people may have normal IgE levels.
- Tests assessing IgE levels in association with skin tests, medical history, and a physical exam may be useful in diagnosing allergies in some people.
