No-biopsy pathway following the interim BSG guidance reliably diagnoses adult coeliac disease.

Recent interim guidance from the British Society of Gastroenterology, aligned to historical paediatric practice, advises a no-biopsy protocol (NBP) for adults with high anti-tissue transglutaminase (tTG-IgA) titres and other clinical factors. A 7-year retrospective review identified 433 patients with positive tTG-IgA. Of these 433, 98 (23%) fulfilled the high titre criteria for an NBP which may have reduced endoscopic burden on the service.
