Can Zöliakie Test help with longevity?

A celiac disease test (HLA-DQ2/DQ8) can indirectly support longevity if it leads to diagnosis and treatment of undiagnosed celiac disease. Untreated celiac causes chronic inflammation, malabsorption, and increased risks of osteoporosis, lymphoma, and other autoimmune conditions—factors that can shorten lifespan. However, the test alone is not a longevity test; it only indicates genetic predisposition. Confirmed diagnosis requires serology and duodenal biopsy. For those with celiac, strict gluten-free diet reduces complications and restores near-normal life expectancy. For individuals without celiac or without risk alleles, the test offers no direct longevity benefit. Evidence is observational: untreated celiac reduces life expectancy, but treatment normalizes it. Caveat: consumer genetic tests for celiac risk should not replace medical diagnosis. Overinterpretation of low-risk results may delay necessary evaluation.
