What role does Zöliakie Test play in Langlebigkeit?

A celiac test (blood test for tTG-IgA, possibly HLA-DQ2/DQ8 genetics) is primarily used to diagnose celiac disease, an autoimmune condition that, if untreated, can lead to chronic inflammation, nutrient malabsorption, and increased mortality. Regarding longevity, the test plays an indirect but important role: early detection and a gluten-free diet can prevent complications such as osteoporosis, lymphoma, and cardiovascular issues. The evidence for diagnostic benefit is strong (human-strong), but the direct impact on lifespan is difficult to quantify. Importantly, MyBody-X does not offer a specific celiac test; IgG food intolerance tests (as mentioned in the context) are not suitable for celiac diagnosis and are not recommended by guidelines. A genetic test for HLA-DQ2/DQ8 (e.g., via MyBody-X DNA tests) can assess risk but does not replace medical diagnosis. For a longevity perspective, correct diagnosis and management of celiac disease are key, not the test alone.
