Evidence check: IgE Allergietest in the context of Allergie

The IgE allergy test (specific immunoglobulin E) is a well-established medical procedure for diagnosing type I immediate hypersensitivity reactions (e.g., pollen, pet dander, foods). The evidence for the underlying immunology and clinical validity is strong (human-strong). However, this applies to standardized tests interpreted by specialists. In consumer tests like the MyBody-X KombiCheck, which measures IgE, clinical embedding is often lacking: results are not diagnostic, may yield false positives or negatives, and are frequently mixed with IgG tests for food intolerances—a scientifically unsupported practice. Moreover, the test panel is limited and not equivalent to comprehensive allergy diagnostics. For reliable allergy assessment, a physician visit with standardized methods (e.g., skin prick test, CAP-FEIA) is essential. The evidence for the specific use in a home-test context is marketing-driven and unclear.
