What role does Zöliakie Test play in gut health?

The celiac test (blood test for IgA antibodies against tissue transglutaminase) is used for early detection of celiac disease, an autoimmune condition triggered by gluten that damages the intestinal lining. Untreated celiac can lead to nutrient malabsorption, inflammation, and long-term gut health issues. However, the test itself does not measure general gut health—it only detects specific antibodies. A positive result requires confirmation via duodenal biopsy. Evidence for test accuracy is moderate, but clinical relevance for gut health is high if celiac is present. Caveat: the test does not assess other gut conditions like IBS or dysbiosis. It is a useful screening tool but not a comprehensive gut health assessment.
