ist in reis gluten — which blood markers matter?

No, rice is naturally gluten-free. Gluten is only found in certain grains (wheat, rye, barley). Therefore, no specific blood markers for gluten are needed when eating rice. However, if celiac disease is suspected, blood tests measure anti-tissue transglutaminase (tTG-IgA), total IgA, and sometimes deamidated gliadin peptide (DGP) antibodies. These markers are only meaningful if the person is consuming gluten. For non-celiac gluten sensitivity, no validated blood markers exist. Rice itself does not contain gluten, so gluten-specific antibody tests are irrelevant on a pure rice diet. For general health assessment, liver enzymes, CRP, and a complete blood count may be useful but are not gluten-specific. Evidence for celiac markers is strong (human-strong); for non-celiac gluten sensitivity, evidence is unclear.
