Order IgE Test | Immunoglobulin E Level TestingImmunoglobulin E, or IgE, is the antibody class most closely tied to allergic responses. A total IgE blood test measures the overall concentration of these antibodies in the bloodstream rather than identifying reactivity to any single substance. Because total IgE reflects a broad immune signal, it is typically used as one piece of a larger clinical picture, not as a stand-alone diagnosis.
About IgE Test | Immunoglobulin E Level Testing in Pasadena
The IgE test quantifies the total amount of immunoglobulin E circulating in the blood.
IgE is one of five antibody isotypes produced by the immune system. It binds to receptors on mast cells and basophils, and when it encounters a matching allergen, it triggers the release of histamine and other mediators that produce classic allergy symptoms such as sneezing, itching, hives, and airway tightening.
A total IgE measurement captures the sum of all IgE in the sample, regardless of what each antibody targets. Elevated total IgE can accompany allergic asthma, allergic rhinitis, atopic dermatitis, and certain parasitic infections. Some people with confirmed allergies have normal total IgE, and some without allergies have mildly elevated levels, so results are interpreted alongside history, symptoms, and other tests.
Total IgE is distinct from allergen-specific IgE testing, which checks for antibodies directed at particular triggers such as pollen, pet dander, or foods. The total IgE test gives a general index of allergic activity; specific tests help identify what the immune system is reacting to. Clinicians often order both when evaluating suspected allergic disease.
