ist reis gluten — which blood markers matter?

Rice is naturally gluten-free, as it does not contain wheat, rye, or barley proteins. However, processed rice products (e.g., rice flakes, rice bread) may be cross-contaminated with gluten – look for a 'gluten-free' label. If you suspect celiac disease or non-celiac gluten sensitivity (NCGS), certain blood markers are relevant. For celiac diagnosis, standard markers include: tissue transglutaminase antibodies (tTG-IgA), deamidated gliadin peptides (DGP-IgA/IgG), and endomysial antibodies (EMA). Total IgA is measured to rule out IgA deficiency, which can cause false negatives. Crucially, these markers are only meaningful while on a gluten-containing diet – a gluten-free diet before testing can skew results. For NCGS, no established blood markers exist; diagnosis is by exclusion and challenge. MyBody-X does not offer a specific gluten intolerance test; these markers are available through medical labs. Evidence: tTG-IgA has high sensitivity and specificity for celiac disease (human-strong). Caveat: a positive test alone is not diagnostic – duodenal biopsy remains the gold standard. Safety note: consult a doctor before starting a gluten-free diet if celiac is suspected.
