Parents often ask whether their child has a gluten issue. Key distinction: celiac disease is an autoimmune condition diagnosed via tTG-IgA blood test and duodenal biopsy, not via IgG food intolerance panels. Many direct-to-consumer 'gluten sensitivity' tests measure IgG antibodies, which lack clinical validation and can yield false positives, leading to unnecessary dietary restrictions. For children with fatigue, digestive issues, or poor growth, consult a pediatrician first. A gluten-free diet before testing can mask celiac disease. Non-celiac gluten sensitivity (NCGS) remains controversial with no validated biomarker. MyBody-X does not offer a specific gluten test for children. Evidence for IgG-based tests is weak (marketing). Rely on medical evaluation, not consumer tests.
