About IgE Test | Immunoglobulin E Level Testing in Normal
The IgE test is a blood test that quantifies total immunoglobulin E, the antibody class most closely associated with allergic responses.
IgE binds to specialized receptors on mast cells and basophils. When an allergen cross-links receptor-bound IgE, these cells release histamine and other mediators that produce allergy symptoms.
Total IgE reflects the overall quantity of the antibody rather than reactivity to any single substance. Because total IgE can be elevated in atopic conditions and also in some non-allergic disorders, results are interpreted alongside a person's history and other findings.
The test requires a blood sample collected by a laboratory professional. Turnaround is typically one to three business days, and preparation follows the laboratory's instructions.
