About IgE Test | Immunoglobulin E Level Testing in Algonquin
The IgE test is a blood-based screen that quantifies total immunoglobulin E.
IgE is one of five antibody classes produced by the immune system. It binds to specialized cells called mast cells and basophils, and when it encounters a matching allergen, it prompts those cells to release histamine and other mediators. That release is what produces familiar allergy symptoms such as sneezing, itching, hives, and wheezing.
A total IgE measurement reports the combined amount of IgE in the sample rather than the amount directed at any one substance. Because of that, it is often used as an initial screen when an allergic condition is suspected. Elevated total IgE can accompany allergic asthma, allergic rhinitis, atopic dermatitis, and some parasitic infections, though results are interpreted alongside a person's history and other findings.
The test requires only a blood draw, and the sample is analyzed in a laboratory. Results are typically reported as a numeric value in international units per milliliter. A clinician uses that number, together with symptoms and possibly allergen-specific testing, to build a fuller picture of immune sensitization.
