Order IgE Test | Immunoglobulin E Level TestingImmunoglobulin E is an antibody class that circulates at very low concentrations in most people. Measuring the total amount of IgE in the blood gives a broad picture of allergic sensitization rather than a reaction to one specific substance.
About IgE Test | Immunoglobulin E Level Testing in Fremont
The total IgE test is a blood test that quantifies the overall concentration of immunoglobulin E antibodies in the bloodstream.
IgE antibodies are produced by the immune system and bind to allergens such as pollen, dust mites, animal dander, certain foods, and some medications. When an allergen cross-links IgE bound to mast cells, those cells release histamine and other mediators that produce allergy symptoms.
Total IgE testing measures the sum of all IgE in the sample, so it does not identify which allergen is responsible. A result above the reference range can support further evaluation with allergen-specific IgE testing, while a result within the reference range does not rule out allergy.
Clinicians use total IgE alongside history, physical examination, and other laboratory results. Conditions such as atopic dermatitis, allergic asthma, allergic rhinitis, and parasitic infections can raise total IgE, and some immune deficiencies are associated with unusually low or high levels.
