What to watch with IgE Allergietest and stress?

An IgE allergy test measures specific antibodies to allergens and indicates sensitization, not the effect of stress. Stress can amplify allergic symptoms by modulating the immune system (e.g., via cortisol and mast cells), but it generally does not alter IgE levels themselves. Studies show a moderate association between chronic stress and increased allergic reactivity, but the evidence is mixed. Therefore, the test is not a stress marker. Be aware that a positive IgE result does not automatically mean clinical allergy—medical correlation with symptoms is required. Stress management may improve quality of life for allergy sufferers but does not replace allergen-specific treatment. Evidence: human-moderate (stress-allergy link) and mechanistic (IgE measurement).
