Because of the major implications of a diagnosis of coeliac disease, professional guidelines recommend that a positive blood test is still followed by an endoscopy/gastroscopy and biopsy.
A gastroscopy is performed using a thin flexible tube (gastroscope) which has a camera and a light on the tip, used to look at the area being examined.
During a gastroscopy, you are sedated and a slim, flexible lighted tube is inserted through your mouth to examine the stomach, oesophagus and duodenum.
