ist reis immer glutenfrei — which blood markers matter?

Rice is naturally gluten-free because it does not contain wheat, rye, or barley. However, cross-contamination can occur in processed rice products (e.g., instant rice, rice cakes), so look for a 'gluten-free' label if you have celiac disease or severe sensitivity. Which blood markers matter? For celiac disease, the tissue transglutaminase antibody (tTG-IgA) is the first-line test (evidence: human-strong). Total IgA should be measured to rule out IgA deficiency, which can cause false-negative results. If IgA-deficient, tTG-IgG or deamidated gliadin peptides (DGP) are alternatives. For non-celiac gluten sensitivity (NCGS), no validated blood markers exist; diagnosis is clinical, based on symptom improvement with a gluten-free diet and relapse upon challenge. MyBody-X tests may include tTG-IgA and DGP, but interpretation requires a physician. A positive antibody result alone does not confirm active celiac disease; duodenal biopsy remains the gold standard. Be cautious with at-home tests – false positives/negatives are possible. If you experience persistent bloating, fatigue, or diarrhea, consult a gastroenterologist rather than relying solely on self-testing.
