hat reis gluten? — which blood markers matter?

Rice is naturally gluten-free, as gluten is only found in grains like wheat, rye, and barley. However, processed rice products or cross-contamination may introduce traces. For diagnosing celiac disease or gluten sensitivity, key blood markers include tissue transglutaminase antibodies (tTG-IgA) as the primary test, along with endomysial antibodies (EMA) and deamidated gliadin peptides (DGP). Total IgA measurement is essential to rule out IgA deficiency, which can cause false negatives. Genetic testing for HLA-DQ2/DQ8 indicates risk but is not diagnostic. Home test kits for these markers may have lower accuracy than venous lab tests; abnormal results require medical confirmation. The evidence for these blood markers is human-strong in clinical settings, but home tests often lack validation. Rice itself is safe for a gluten-free diet, but always check labels for additives.
