Order IgE Test | Immunoglobulin E Level TestingThe IgE test measures the total amount of immunoglobulin E in the blood. IgE is one of five antibody classes produced by the immune system, and it appears in the smallest concentrations of any of them under ordinary circumstances. Because IgE is central to allergic sensitization, a total IgE measurement can serve as a broad indicator when allergic disease is suspected.
About IgE Test | Immunoglobulin E Level Testing in Berkeley
Immunoglobulin E is the antibody class most closely tied to allergic responses.
IgE binds to receptors on mast cells and basophils. When an allergen cross-links the bound IgE, those cells release histamine and other mediators, producing the symptoms associated with allergic reactions. Total IgE reflects the sum of all allergen-specific IgE in circulation rather than the response to any single substance.
A total IgE result is interpreted alongside a person's history and other findings. Elevated levels are often seen in atopic conditions such as allergic rhinitis, asthma, and atopic dermatitis, and in parasitic infections. Some people with clear allergies have normal total IgE, and some without allergic disease have higher values, so the test is rarely diagnostic on its own.
The test requires a standard blood draw, and the laboratory reports a numeric concentration that is compared with a reference range. Results are typically available within one to three business days. Follow the collecting lab's instructions before the draw. Because total IgE does not identify which allergens are involved, it is frequently paired with allergen-specific testing when a more detailed picture is needed.
