Is IgE Allergietest useful for Sport?

An IgE allergy test can be useful for athletes only if they have specific allergic symptoms (e.g., seasonal rhinitis, asthma, urticaria) that impair performance. However, many studies show that positive IgE findings often lack clinical relevance – a positive test alone does not confirm a real allergy. For asymptomatic athletes, there is no proven performance benefit. The evidence is mixed: IgE tests are established for diagnosing suspected allergies, but there is no evidence for general screening in sports. Caution: misinterpretation can lead to unnecessary diets or medications. A medical workup with history and possibly provocation tests is preferable.
