ist reis glutenhaltig — can a microbiome test help?

Rice is naturally gluten-free and safe for people with celiac disease or gluten sensitivity, provided it is not cross-contaminated. However, a microbiome test cannot directly determine whether rice contains gluten or diagnose gluten-related disorders. Celiac disease is diagnosed through blood tests (antibodies) and duodenal biopsy, not stool samples. A microbiome test may offer indirect clues about gut dysbiosis associated with celiac, but the evidence for clinical utility is weak. Genetic predisposition (HLA-DQB1) is assessed via DNA tests, not microbiome analysis. Caveat: Microbiome tests are not a substitute for medical diagnosis and are not recommended by guidelines for celiac evaluation.
