Transglutaminase Iga Antibodies in A Celiac Disease Mass Screening and the Role of Hla-Dq Genotyping and Endomysial Antibodies in Sequential Testing.
OBJECTIVES:: To evaluate hypothetical screening strategies in a Swedish celiac disease (CD) mass screening. PATIENTS AND METHODS:: Out of 10041 Swedish sixth-graders born in 1993 invited to a population-based CD mass screening, 7208 participated. Anti-tissue-transglutaminase (tTG) IgA were analyzed in all children and total serum IgA (s-IgA) in 7161 children. Additional analyses of tTG-IgG, endomy
