When is IgE Allergie Training actually useful?

IgE allergy training (allergen immunotherapy, AIT) is useful only when a clinically relevant IgE-mediated allergy has been confirmed by a physician. Home IgE tests detect sensitization, not clinical allergy—many sensitized individuals have no symptoms. Immunotherapy is evidence-based for conditions like allergic rhinitis, asthma, and insect venom allergy when symptoms are moderate to severe and medications are insufficient. The evidence for AIT efficacy is strong (human-strong) for these indications, but home tests alone cannot determine candidacy. They may serve as a screening tool, but false positives and negatives are common. A thorough medical evaluation including history, skin prick tests, and sometimes provocation tests is essential before starting AIT. Without a confirmed diagnosis, allergy training is not useful and may carry risks such as systemic allergic reactions. Therefore, IgE testing is only a first step; the decision for training must be made by an allergist based on clinical criteria.
