Evidence check: Zöliakie Test in the context of Allergie

The question of a celiac test in the context of allergies is reasonable, but the evidence must be clearly separated: celiac disease is autoimmune, not an allergy. A celiac test (e.g., tTG-IgA, endomysial antibodies) is indicated for suspected gluten intolerance, but not as an allergy test. The provided context contains no specific information on celiac testing; it only references intolerance tests in general. The evidence for such tests in MyBody-X is rated as 'marketing' or 'unclear' because no validated studies or clinical guidelines are cited. A celiac test should only be performed on medical indication, not as a self-test. Consumers should understand that a negative allergy test does not rule out celiac disease. Evidence for celiac screening in the general population is moderate, but not in the allergy context. Safety note: If celiac disease is suspected, test before starting a gluten-free diet, as diet can skew results.
