Concept	Alvarado score
Description	Clinical scoring system used to determine the likelihood of appendicitis based on symptoms, signs and laboratory test results.
Use	Use to determine the likelihood of appendicitis based on symptoms, signs and laboratory test results. The total score, derived by adding up the individual scores for each of the 8 items ranges from 0 to 10 with score weights allocated thus: +2 points - Right lower quadrant tenderness +1 point - Elevated temperature (>37.3°C or 99.1°F) +1 point - Rebound tenderness +1 point - Migration of pain to the right lower quadrant +1 point - Anorexia +1 point - Nausea or vomiting +2 point - Leukocytosis > 10,000 +1 point - Leukocyte left shift A CT scan is recommended for scores 4-6 A surgical consultation for scores ≥ 7. For scores ≤ 3: a CT scan is not needed due to the low probability of appendicitis.
Purpose	To determine the likelihood of appendicitis based on symptoms, signs and laboratory test results.
