Alvarado Scoring System in Acute Appendicitis


Alvarado score is the most widely used clinical and laboratory-based scoring system to assist the diagnosis of acute appendicitis.

When the Alvarado score is 5 to 6, abdominal ultrasound or contrast enhanced CT examination helps to confirm the diagnosis of acute appendicitis. And, thus negative appendicectomy can be avoided. Clinical features of acute appendicitis contribute more to Alvarado scoring system than laboratory tests.
