Does anyone know if an accurate diagnosis of coeliac can be made from biopsys if not been eating wheat and gluten. My bloods have always come back negative because I cut right down a long time before doing the blood tests. Iv had colonoscopy today and 12 biopsys taken consultant told me I would have to go back to eating wheat and gluten for at least 2 months to get a positive on blood test but made me believe that biopsy is the only way to get a proper result if I didn't. Any one else had diagnosis from biopsys without having to eat wheat and gluten??
