Celiac.com 08/07/2003 - An Italian study conducted by Dr. L. Bonomo and colleagues and published in the July 2003 edition of Scandinavian Journal of Gastroenterology concludes that A significant proportion of coeliacs may be missed if relatives are screened by serology only, while the efficacy of sorbitol H2-BT in screening relatives is confirmed. This study confirms that neither a breath test nor serology can replace intestinal biopsy, which remains the gold standard for the diagnosis of celiac disease, thus confirming the continued importance of performing biopsies for diagnosing celiac disease. The studys goal was to determine the diagnostic capabilities of serological tests (antigliadin (AGA), antiendomysium (EMA) and anti-tissue transglutaminase (anti-tTG)) and sorbitol H2 breath test (H2-BT) in the detection of celiac disease in first-degree relatives. The study screened 111 first-degree relatives of 37 celiac families using both test methods to determine candidates for small bowel biopsy. First-degree relatives with abnormal test results underwent a small bowel biopsy, as did those with negative serological and H2 breath test results who had clinical complaints or suspected that they may have celiac disease.
