Antibody Concentrations Decrease 14-fold in Children With Celiac Disease on a Gluten-free Diet but Remain High at 3 Months

Celiac disease can be identified by a serologic test, for immunoglobulin A (IgA) against tissue transglutaminase (IgA-TTG), in a large proportion of children. However, the increased concentrations of antibody rarely normalize within the months after children are placed on a gluten-free diet (GFD). Early serological predictors of sufficient adherence to gluten-free diet are required for optimal treatment.
