A number of clinical and laboratory based scoring systems have been devised to assist the diagnosis of appendicitis. The most widely used is the Alvarado score:
| Migratory right iliac fossa pain | 1 point |
| Anorexia | 1 point |
| Nausea and vomiting | 1 point |
| Right iliac fossa tenderness | 2 points |
| Rebound tenderness | 1 point |
| Fever | 1 point |
| Leukocytosis | 2 points |
| Shift to left (segmented neutrophils) | 1 point |
| Total score | 10 points |

A score of 7 or more is strongly predictive of acute appendicitis.
In patients with an equivocal score of 5-6, CT scan further reduces the rate of negative appendectomy.
