In the provided contexts, there is no direct evidence linking HLA-DQ2 to longevity. Theoretically, undiagnosed celiac disease could impair health through chronic inflammation, malabsorption, and nutrient deficiencies, potentially reducing lifespan. However, this is speculative; robust human studies connecting HLA-DQ2 status to extended or shortened lifespan are lacking. The evidence level is therefore classified as unclear. Testing for HLA-DQ2 may be useful if celiac symptoms are present, but it should not be used as a longevity biomarker.

However, the predictive value for asymptomatic individuals is limited: the genetic predisposition (HLA-DQ2/DQ8) is common (~30% of the population), but only ~1% actually develop celiac disease. A positive genetic test alone does not justify a gluten-free diet without clinical confirmation. The evidence for population screening to extend lifespan is moderate – benefits are clearer in symptomatic or high-risk groups. Without a confirmed diagnosis, an unnecessary gluten-free diet can lead to nutritional deficiencies and social burden.

Celiac disease is an autoimmune condition triggered by gluten, leading to intestinal inflammation, malnutrition, and increased mortality if untreated. Early testing (blood anti-tTG antibodies, possibly duodenal biopsy) can diagnose the disease and, through a gluten-free diet, prevent complications. However, evidence for a direct impact of such testing on longevity is weak: no randomized trials show that screening asymptomatic individuals extends lifespan. Genetic tests (HLA-DQ2/DQ8) indicate predisposition, not disease. The link to longevity is indirect—via avoiding complications like lymphoma or osteoporosis—but not proven. Therefore, the evidence level is 'unclear'.
