Figure 3From: Urinary amylase / urinary creatinine ratio (uAm/uCr) - a less-invasive parameter for management of hyperamylasemia Receiver operating characteristic curves for the urine level of creatinine (uAm, broken line), amylase creatinine clearance ratio (ACCR, dotted line) and the level of urinary amylase divided by urine creatinine (uAm/uCr, solid line) as predictors of abnormal level of serum amylase. The area under the curve for uAm/uCr is significantly greater than that for uAm and ACCR.Back to article page
