Myths vs facts: AllergieCheck | IgE-Antikörper Test and Sport

The MyBody-X AllergieCheck measures IgE antibodies but is marketed as a lifestyle test, not a diagnostic tool. A common myth in sports is that elevated IgE levels directly indicate a performance-harming food allergy. Fact: Elevated IgE alone does not confirm an allergy; false positives are common. Additionally, physical exertion itself can transiently raise IgE levels. Therefore, the test cannot reliably tell an athlete which foods impair performance. A proper diagnosis requires a physician with history, provocation tests, and possibly specific IgE. Athletes should not change their diet based solely on this test. The evidence for sport-specific utility is weak and largely based on marketing. Anyone suspecting real allergies or intolerances should see an allergist.
