IgE Allergietest: what are common causes?

An IgE allergy test measures immunoglobulin E levels, which are central to allergic reactions. Common causes of elevated IgE include seasonal allergies (pollen, grasses), perennial allergens (dust mites, mold, pet dander), and food allergies (peanuts, egg, milk). Also insect venom or drug allergies can raise IgE. Non-allergic causes include parasitic infections (e.g., helminths) and rare immune disorders (hyper-IgE syndrome). Importantly, a positive IgE result alone does not confirm clinical allergy – it must be interpreted with symptoms and history. Consumer tests like MyBody-X provide lab values but not a diagnosis. The evidence for IgE measurement is strong (human-strong), but interpretation without a physician is often misleading. Marketing may promise quick answers, yet many elevated levels are benign or false-positive. For suspected allergy, an allergist using skin prick tests and oral challenges remains the gold standard. Safety note: self-eliminating foods without diagnosis can lead to nutritional deficiencies.
