Myths vs facts: Zöliakie Test and Allergie

The provided context does not contain specific information on celiac testing or allergies. In general, a celiac genetic test (e.g., HLA-DQ2/DQ8) indicates predisposition, not diagnosis. Confirmation requires antibody tests (tTG-IgA) and duodenal biopsy. Allergy tests (IgE) detect a different immune pathway than the autoimmune reaction in celiac disease. Confusion between celiac disease, wheat allergy, and gluten sensitivity is common. Without medical evaluation, a DNA test alone cannot provide a definitive answer. The evidence from the context is weak; this answer relies on general medical knowledge.
