Alvarado Score (MANTRELS)

Evaluates the likelihood of acute appendicitis.

Parameters

Alvarado Score (MANTRELS) Result

--
FormulaSum of MANTRELS criteria. Tenderness (RLQ) and Leukocytosis are worth 2 points each, others are 1 point.

Clinical Pearls

Highly sensitive for ruling out appendicitis at low scores (<4) and useful for deciding who needs imaging vs direct surgical consultation.

Limitations

Less accurate in children and women of child-bearing age where gynecological pathology can mimic appendicitis. Imaging is frequently still required in moderate/high risk patients.
