Classic clinical score for the likelihood of acute appendicitis.
The Alvarado Score (MANTRELS) is a GI & Liver scoring tool used in paediatric practice. Classic clinical score for the likelihood of acute appendicitis. It scores 8 criteria and interprets the total across 4 bands, so the number always arrives with the severity it implies rather than on its own. In PediAid each criterion is shown as a labelled option with the weight it carries, so the total can be checked rather than taken on trust.
8. They are Migration of pain to RLQ; Anorexia; Nausea or vomiting; Tenderness in RLQ; Rebound pain; Elevated temperature ≥ 37.3 °C; and others.
The total is interpreted as: any score - Unlikely: score 0-4 - appendicitis unlikely. Consider discharge with safety-netting or an alternative diagnosis; 5 points or more - Possible: score 5-6 - compatible with appendicitis. Observation and/or imaging recommended; 7 points or more - Probable: score 7-8 - probable appendicitis. Surgical referral; 9 points or more - Very probable: score 9-10 - very probable appendicitis. Urgent surgical referral.
No. It is a structured way to record and communicate severity. A clinician concerned about a child should act on that concern regardless of the total.
Total range 0-10. Less well validated in young children than the Paediatric Appendicitis Score.
Yes. Score definitions are bundled with the PediAid app, so the score computes without a connection.
