What to watch with IgE Allergietest and Sport?

When combining an IgE allergy test with sports, key considerations include: a positive IgE result indicates sensitization, not necessarily a clinical allergy. Many people have elevated IgE without symptoms. Exercise can trigger or worsen allergic reactions (e.g., exercise-induced anaphylaxis, food-dependent exercise-induced anaphylaxis). Home tests may not distinguish between clinically relevant and irrelevant sensitizations, leading to false positives and unnecessary dietary or activity restrictions. For athletes or active individuals, an allergist should interpret IgE results in context of history and possibly perform provocation tests. Relying solely on a consumer IgE test for sport decisions is not evidence-based. Evidence: human-moderate (observational studies on IgE and exercise-induced reactions).
