Ranson's Criteria (On Admission) for Pancreatitis Calculator

Sum of 5 binary admission predictors (age > 55, WBC > 16, Glu > 200, LDH > 350, AST > 250).

Compute the Ranson's Criteria score using the 5 admission predictors of severe acute pancreatitis: age > 55 yr, WBC > 16,000/µL, glucose > 200 mg/dL, LDH > 350 IU/L, AST > 250 IU/L. Score 0–2 = ~1 % mortality; 3–4 = 15 %; 5–6 = 40 %; ≥ 7 = ~100 %. Pair with the 6-criteria 48-hour set for full assessment.
