How to get diagnosed

Diagnosis relies upon proving that the small bowel lining shows the typical abnormality (damage) of Coeliac Disease. This can only be done by carrying out a small bowel biopsy test (Endoscopy), where a special optic fibre instrument is passed through the mouth with direct viewing of progress by the doctor, who is able to pass a small biopsy forcep through the instrument when it reaches the upper small bowel. This allows a tiny piece of bowel lining to be removed for microscopic examination. Since a biopsy test is essential for proper diagnosis, referral to either an adult or child specialist gastroenterologist will usually be necessary.

A specific panel of blood tests that measures antibodies to gluten are available as a screening aid in the diagnosis of Coeliac Disease. These tests also give doctors a simple and rapid means to help decide which members of an affected family should have biopsies. These tests may also help to reduce the incidence of delayed diagnosis.
