Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
Specificity is lower in women of reproductive age, where gynaecological causes mimic the presentation.
The Paediatric Appendicitis Score is preferred in children and uses cough or percussion tenderness instead of rebound.
