Small Intestinal Biopsy for Celiac
Small intestinal biopsy for celiac samples the duodenum during endoscopy while you still eat gluten—patchy damage means multiple biopsies improve detection.
Small intestinal biopsy for celiac samples the duodenum during upper endoscopy to score villous atrophy and inflammation while gluten is still in the diet. Multiple biopsies increase detection because damage can be patchy.
Recovery on a strict gluten-free diet can partially reverse changes over months to years.
Common questions
-
Is biopsy always required for adults?
Guidelines vary by age, serology strength, and regional practice—some high-titer cases skip biopsy under specialist criteria. Never skip professional workup because a direct-to-consumer test suggested celiac.
