    When to Use
    Pearls/Pitfalls
    Why Use

    Use in pediatric or adult patients with suspected appendicitis (large external validation cohort included ages 2-96 years).

    Requires C-reactive protein value, which is sometimes not part of the routine battery of tests for abdominal pain.

    • Outperforms the Alvarado Score in a large (n = 941 consecutive patients) external validation cohort (De Castro 2012) with an AUROC of 0.96.
    • May help avoid the need for CT imaging.
