The value of the amylase/creatinine clearance ratio in the diagnosis of acute pancreatitis.
Acute pancreatitis usually confronts the clinician with a difficult diagnostic task. For years, the primary laboratory diagnostic tests were the serum and urine amylase and the serum lipase determinations. Recent studies have introduced the concept of the amylase/creatinine clearance ratio as a means of increasing the specificity of the laboratory diagnosis. This paper reviews the laboratory evaluation of acute pancreatitis with emphasis on the rationale, derivation, and specificity of the amylase/creatinine clearance ratio.
