Evidence check: AllergieCheck | IgE-Antikörper Test in the context of longevity

The Allergy Check (IgE antibody test) measures specific IgE antibodies against allergens and is a well-established clinical tool for diagnosing type I allergies. In the context of longevity, there is no direct evidence that this test alone influences lifespan. However, chronic allergic inflammation—such as untreated hay fever or asthma—can contribute to systemic immune activation and oxidative stress, potentially accelerating biological aging. A positive IgE test indicates sensitization, not necessarily clinically relevant allergy. Interpretation requires a physician who considers symptoms and history. For longevity strategies, it is more informative to monitor general inflammatory markers (e.g., hs-CRP, IL-6) and lifestyle factors. The IgE test alone does not provide a sufficient basis for anti-aging interventions. Evidence: clinical practice, but not specific to longevity. Caveat: overinterpreting IgE levels without symptoms may lead to unnecessary dietary restrictions or avoidance behaviors.
