How are AllergieCheck | IgE-Antikörper Test and longevity related?

The AllergieCheck (IgE antibody test) measures specific IgE levels against allergens and is primarily used for allergy diagnosis. A direct link to longevity cannot be established from the provided knowledge base. While chronic inflammation from untreated allergies may contribute to age-related diseases, IgE alone is not a validated biomarker for longevity. Current evidence shows that IgE levels are influenced by many small-effect genetic variants and strong environmental factors. Some GWAS associations (e.g., IL4, FCER1A) exist, but they explain only a small fraction of variance. Without clinical symptoms or repeated measurements, the predictive value for longevity is low. No longitudinal studies directly connect IgE to mortality or healthy aging in the given context. Therefore, the evidence grade is 'unclear'. Consumers should be aware that this test is designed for allergy management, not longevity assessment.
