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

The AllergieCheck (IgE antibody test) measures specific or total IgE levels and is used to diagnose allergies – not longevity. Fact: Elevated IgE can indicate allergies, parasites, or rare immune disorders, but there is no robust evidence linking IgE levels directly to lifespan. Myth: Some providers market IgE tests as 'longevity markers' – this is not scientifically supported. Longevity is influenced by genetics, lifestyle, inflammation status, and microbiome, not by IgE alone. Caveat: A normal IgE test does not rule out allergies; an elevated level without symptoms is often clinically irrelevant. Evidence for IgE in allergy diagnosis is human-strong, but for longevity it is marketing-based or unclear. Consumers should only take IgE tests when there is a specific allergy suspicion and under medical guidance.
