Order IgE Test | Immunoglobulin E Level TestingImmunoglobulin E, or IgE, is the antibody class most closely tied to allergic responses. Measuring total IgE in the blood gives a broad view of how much of this antibody is present, which can support the evaluation of allergic disease.
About IgE Test | Immunoglobulin E Level Testing in Granite City
The IgE test quantifies the overall concentration of immunoglobulin E antibodies circulating in the bloodstream.
IgE is one of five antibody isotypes produced by the immune system. It binds to mast cells and basophils, and when it encounters a matching allergen, it triggers the release of histamine and other mediators that produce allergy symptoms.
Total IgE testing measures the sum of all IgE antibodies rather than the amount directed at any single allergen. Because of this, an elevated result is not specific to one substance. It is typically interpreted alongside a clinical history and, when appropriate, allergen-specific testing.
Conditions such as allergic rhinitis, asthma, atopic dermatitis, and parasitic infections can raise total IgE. Some individuals have elevated levels without clear symptoms, and others with allergy have results within the reference range, so the test is best used as one part of a broader assessment.
