How are IgE Allergietest and Langlebigkeit related?

The direct link between IgE allergy tests and longevity is scientifically weak. IgE tests measure specific immune responses to allergens and are valid for diagnosing type I allergies (e.g., hay fever, food allergies). Chronic allergic inflammation could theoretically affect lifespan through increased oxidative stress or immune activation, but robust human studies demonstrating a causal relationship are lacking. Some epidemiological data suggest an inverse association between certain allergies and cancer risk, but evidence is mixed and not actionable. From a longevity research perspective, IgE levels are not an established biomarker. Instead, factors like inflammatory markers (CRP, IL-6), telomere length, or metabolic health should be prioritized. Caution is advised against commercial offerings that market IgE tests as a 'longevity check' – this is misleading. An IgE test is useful when allergy is suspected, not for extending lifespan.
