Total IgE

Measures immunoglobulin E level; elevated in allergic reactions

About This Test

The Total IgE test measures the amount of IgE in the blood. Elevated levels suggest the body may overreact to allergens or indicate parasitic infections, vasculitis, or immune system conditions. This blood test identifies immunoglobulin E antibodies and is used to evaluate allergy symptoms, investigate suspected parasitic infections, screen children with family allergy histories, assess allergic respiratory disease, confirm food sensitivity in asthma/angioedema patients, and test insect venom sensitivity.
