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

The myth is that a positive IgE test (AllergieCheck) directly proves that allergies are ruining your sleep. The fact: IgE antibodies indicate sensitization—your immune system has produced antibodies to a substance—but this does not confirm clinical allergy. Many people with positive IgE have no symptoms. Sleep disturbances from allergies (e.g., nasal congestion, itching, asthma) require a clear symptom-allergen link, which a home test cannot establish. Sleep problems are multifactorial; relying solely on an IgE test may lead to unnecessary dietary restrictions or false reassurance. Evidence for the test's ability to improve sleep is lacking—it's based on general medical knowledge, not validated product studies. For sleep issues, a clinical evaluation (including history, possibly a sleep study) is far more useful than a direct-to-consumer allergy test.
