Alvarado score
Alvarado Score is a clinical scoring system used in the diagnosis of appendicitis. The score was developed by Dr. Alfredo Alvarado in 1986 and is used to predict the likelihood of appendicitis in patients presenting with abdominal pain.
Scoring System[edit | edit source]
The Alvarado Score is based on eight clinical features, each of which is assigned a certain number of points. The total score can range from 0 to 10.
- Symptoms
- Migratory pain to the right lower quadrant (1 point)
- Anorexia or ketonuria (1 point)
- Nausea or vomiting (1 point)
- Signs
- Tenderness in the right lower quadrant (2 points)
- Rebound pain (1 point)
- Fever of 37.3°C (99.1°F) or higher (1 point)
- Laboratory findings
- Leukocytosis (white blood cell count greater than 10,000/mm³) (2 points)
- Neutrophilia (neutrophil count greater than 75%) (1 point)
Interpretation[edit | edit source]
The interpretation of the Alvarado Score is as follows:
- Score of 1-4: Low probability of appendicitis
- Score of 5-6: Intermediate probability of appendicitis
- Score of 7-8: High probability of appendicitis
- Score of 9-10: Very high probability of appendicitis
Limitations[edit | edit source]
While the Alvarado Score is a useful tool in the diagnosis of appendicitis, it is not without limitations. It should not be used as the sole method of diagnosis, but rather as a part of a comprehensive clinical assessment.
