Immunohistologic analysis of the duodenal bulb

Post written by Tarcisio Not, MD, from the Institute for Maternal and Child Health–IRCCS “Burlo Garofolo” Trieste, Trieste, Italy. This prospective study investigates whether histological analysis of the duodenal bulb combined with intestinal IgA anti-tissue transglutamonase deposit immunoassay makes celiac disease diagnosis possible in at-risk children with low concentrations of serum anti-tissue transglutaminase. Anti-tissue transglutaminase …
