The aim of this study was to evaluate the diagnostic value of red blood cell distribution width (RDW) in children with acute appendicitis. ⋯ Children with histologically proven acute appendicitis have higher RDW than children without appendicitis, but the diagnostic value of RDW was not superior to WBC or CRP in children with acute appendicitis. Although higher RDW may be valuable for aiding the diagnosis of acute appendicitis in children, it is not a useful marker for predicting perforated appendicitis.
