 The purpose of this study was to assess the diagnostic utility of serum-lucine-rich alpha-2-glycoprotein-1, LRG1, in pediatric patients with acute abdominal pain, admitted to the emergency surgical unit, in order to make a prompt and accurate diagnosis of acute appendicitis. The results showed that LRG1 levels were significantly higher in the group of children with pathohistologically confirmed acute appendicitis than in the control group, at 350.3 μg-mL, inner quartile range, IQR 165.2 to 560.3, and 25.7 μg-mL, IQR 14.7 to 36.8, p less than 0.001, respectively. Furthermore, each of the examined laboratory inflammatory markers provided a significantly higher values in the acute appendicitis group compared to the control group, white blood cell, count 14.6 times 109 slash L, IQR 12.7, 18.7, versus.
