CRP and alkaline phosphatase measurement: A white blood cell (WBC) count > 20 G/l, C-reactive protein (CRP) > 15 mg/dl, hematocrit > 44% and blood urea nitrogen (BUN) > 25 mg/dl are established prognostic parameters in early acute pancreatitis.[5] Multivariate logistic regression analysis was performed to test the influence of WBC, CRP, hematocrit, BUN at admission and history of AP as well as age, gender and BMI on the development of severe complications and mortality.
