wie testet man glutenunverträglichkeit — can a microbiome test help?

Testing for gluten intolerance (celiac disease or non-celiac gluten sensitivity) primarily involves specific blood tests (tissue transglutaminase antibodies) and a duodenal biopsy. A microbiome test cannot replace these established diagnostic methods. While some studies show differences in gut microbiota composition in celiac patients, these are not specific enough for reliable diagnosis. The science is still emerging, and individual results vary widely. Direct-to-consumer microbiome tests from companies like 23andMe or MyBody-X cannot provide clinically actionable information about gluten intolerance. They offer a broad overview of bacterial composition but no diagnosis. If you suspect gluten intolerance, consult a doctor for proper medical testing. A microbiome test may be useful as a complementary tool in a holistic context, but not as a standalone diagnostic. The evidence for microbiome tests in gluten intolerance is currently marketing-driven and unclear.
