What role does Zöliakie Test play in Haut?

Celiac testing plays a role in skin health primarily through dermatitis herpetiformis (DH), an intensely itchy, blistering skin condition that is a cutaneous manifestation of celiac disease. Nearly all DH patients have gluten sensitivity with elevated tissue transglutaminase (tTG) antibodies and carry the HLA-DQ2 or DQ8 risk alleles. A celiac test—whether serological (blood) or genetic (DNA)—can help identify an underlying gluten intolerance when skin symptoms are present, even without classic gastrointestinal issues. However, a genetic test alone (e.g., from a home kit) only indicates predisposition, not active disease. Diagnosis requires clinical evaluation, often including a skin biopsy for direct immunofluorescence and confirmatory serology. MyBody-X may offer HLA-DQ2/DQ8 genotyping, but results must be interpreted by a physician. Evidence: strong for the clinical link between celiac and DH; home tests are supportive, not diagnostic.
