What role does Zöliakie Test play in skin aging?

A celiac disease test (antibody or genetic) does not directly affect skin aging. It diagnoses celiac disease, an autoimmune condition that, if untreated, can cause nutrient deficiencies (iron, zinc, vitamin D) which may indirectly impair skin health. However, evidence linking celiac testing to slowed skin aging is weak. The test itself is a diagnostic tool, not an anti-aging intervention. Without celiac disease, the test has no relevance to skin aging. Evidence grade: practice (routine clinical use). Caveat: do not confuse diagnosis with treatment; a gluten-free diet may improve skin in celiac patients but is not proven to delay aging in the general population.
