Ranson criteria are useful in assessing prognosis in early acute pancreatitis. The more of the criteria are met the higher the mortality. Ranson criteria are assessed both at admission and at 48 hours.

white blood count: >16 000/mL
blood glucose level: >11.0 mmol/L
lactate dehydrogenase (LDH): >350 IU/L
aspartate aminotransferase (AST): >250 U/L

At 48 hours

packed cell volume: decrease >10% from admission
urea: increase >1.8 mmol/L from admission
- equivalent to blood urea nitrogen (BUN): increase >5 mg/dL from admission
calcium: <2 mmol/L
oxygen partial pressure: <60 mmHg
base deficit: >4 mmol/L
fluid sequestration: >6 L
