What should I know about Gluten Labor?

The term 'Gluten Labor' is not standard; you likely mean lab tests for gluten sensitivity. Key point: IgG tests for gluten are not scientifically valid (PMC5004213). They often produce false positives and are not recommended by allergy experts. For reliable diagnosis of celiac disease or gluten sensitivity, validated tests such as tTG-IgA serology and duodenal biopsy are required. Even for athletes with bloating, IgG results for gluten are unreliable; use breath tests or celiac serology instead, and consult a dietitian before eliminating gluten. Avoid self-diagnosis based on commercial IgG panels, as unnecessary gluten removal can lead to nutrient deficiencies. Evidence is moderate – based on a review article, not a clinical trial. Treat such tests as marketing, not evidence-based medicine.
