ist dinkelbrot glutenfrei — which blood markers matter?

Spelt bread is not gluten-free. Spelt is an ancient wheat species and contains gluten (gliadin and glutenin), which can trigger symptoms in celiac disease or non-celiac gluten sensitivity (NCGS). For celiac disease diagnosis, specific blood markers are key: tissue transglutaminase antibodies (tTG-IgA) and deamidated gliadin peptides (DGP-IgA/IgG) – both have high sensitivity and specificity. A total IgA level is needed to rule out IgA deficiency, which could cause false-negative results. For NCGS, no validated blood markers exist; diagnosis is by exclusion and diet. Inflammatory markers like hsCRP or fecal calprotectin may be elevated in gut dysbiosis or chronic inflammation but are not gluten-specific. Consumer blood tests for gluten sensitivity often lack clinical validation – professional evaluation is recommended. Note: If celiac disease is suspected, gluten must still be consumed before blood draw to avoid false negatives.
