How are Zöliakie Test and longevity related?

A celiac test (typically tTG-IgA antibodies, sometimes HLA-DQ2/DQ8 genotyping) has an indirect relationship with longevity. Untreated celiac disease causes chronic inflammation, malabsorption of key nutrients (iron, vitamin D, calcium), and increased risks for osteoporosis, lymphoma, and cardiovascular disease—all of which can shorten lifespan. Early diagnosis and strict gluten-free diet restore gut health, reduce inflammatory markers, and improve nutrient status, potentially lowering mortality. Evidence for the health benefit of diagnosis is human-strong (studies show reduced mortality in treated patients), but the direct link between the test itself and longevity is moderate. The test is a risk-reduction tool, not a direct longevity predictor. Caveats: positive serology requires confirmatory biopsy; false negatives occur in IgA deficiency. Consumer tests like those from MyBody-X may include celiac markers in intolerance or longevity panels—clinical validity depends on proper execution and medical interpretation.
