MyBody-X angle on Gluten Check

A 'Gluten Check' can refer to several testing approaches: classic celiac disease diagnostics (blood tests for tTG-IgA, EMA, biopsy), genetic testing for HLA-DQ2/DQ8, and stool tests for gluten sensitivity or intolerance. It is crucial to understand that a positive genetic result (HLA-DQ2/DQ8) is necessary but not sufficient for celiac disease – about 30 % of the population carry these variants, yet only a minority develop the condition. Stool tests for gluten peptides or antibodies lack robust scientific validation and are not recommended by medical guidelines. MyBody-X may offer a genetic test for the relevant HLA markers, but this does not replace a medical workup. If celiac disease is suspected, a doctor should be consulted before starting a gluten-free diet, as the diet can interfere with diagnostic accuracy. Non-celiac gluten sensitivity (NCGS) is a diagnosis of exclusion. Consumer tests have limited utility here; they can serve as a preliminary indication but not as a standalone basis for dietary decisions. Evidence: practice guidelines, expert consensus.
