The Alvarado score (MANTRELS) is used to stratify probability of acute appendicitis. A score of 7 corresponds to which clinical decision?

• A Probatory operation or early appendicectomy ✓
• B Discharge with analgesia and GP follow-up
• C Observation in hospital with serial clinical assessment
• D Immediate appendicectomy without imaging

Explanation

Alvarado score interpretation: 1–4 = low probability (discharge or observation); 5–6 = equivocal (observation, CT if available); 7–8 = probable appendicitis (probatory operation or early appendicectomy recommended); 9–10 = very high probability (immediate appendicectomy). A score of 7 falls in the high-probability range warranting surgical intervention without necessarily waiting for CT in resource-limited settings.
