Screening for coeliac disease using anti‐tissue transglutaminase antibody assays, and prevalence of the disease in an Australian community

Abstract

The prevalence of anti-tTG antibodies in this population is 1.56%; the prevalence of CD is at least 0.56%. The utility of a single, positive result of an anti-tTG assay in screening for CD in the community is poor, and repeat and/or collateral assessment with different assays may decrease the need for gastroscopy and distal duodenal biopsy.
