In our series, the results of the imaging methods (CT and ultrasound) were prospectively evaluated and compared with the scores based on physiologic and health evaluation system (Ranson score, Glasgow score, APACHE II score), and biochemical parameters (CRP, leukocyte count, aminotransferases, serum albumin level, serum amylase level) with intention to predict the severity of AP. The gene discussed is CRP; the disease is alkaline phosphatase measurement.
