Common mistakes around IgE Allergie Alltag

Common mistakes in daily life regarding IgE-mediated allergies include misinterpreting test results. A positive IgE level (e.g., to foods or pollen) does not necessarily indicate a clinical allergy – many individuals have specific IgE without symptoms (sensitization without allergy). Another mistake is overemphasizing the IgE concentration: the level does not reliably predict symptom severity. Cross-reactivity (e.g., between birch pollen and apples) is often overlooked, leading to unnecessary food avoidance. Many people also rely on IgG tests, which do not diagnose IgE allergies. Self-medication with antihistamines without proper diagnosis can mask symptoms and delay emergency treatment (e.g., epinephrine). In daily life, patients should learn to recognize anaphylaxis and use auto-injectors correctly. Evidence is strong (guidelines from EAACI/AAAAI, clinical studies).
