Antibody blood test : The definitive test is intestinal endoscopy with duodenal biopsy but screening for celiac disease aka gluten enteropathy is by a blood test for antibodies associated with the disease - ttg-a & ttg-g. Serum IgA is also obtained. If the patient has not been on gluten for a while antibody levels often fall into the normal range.
