Combined serum amylase and lipase determinations for diagnosis of suspected acute pancreatitis.
Serum amylase and lipase measurements are often used to diagnose acute pancreatitis. This study addresses the question of whether it is advantageous to order serum amylase and lipase tests simultaneously. We evaluated performance of the two tests separately and in combination through a retrospective study of patients for whom both amylase and lipase determinations were ordered. Initial analysis...
متن کاملPersistence of increased amylase and lipase concentrations in acute pancreatitis.
We question the variations in serum concentrations of lipase and amylase during acute pancreatitis reported by Loft and Lu (1). In the caption for their Figure 3, the authors stated that the graphs of the two enzymes in a patient with acute pancreatitis demonstrated “characteristic changes with time.” Serum concentrations of both enzymes peaked on the fourth day after onset and still had not de...
متن کاملA critical evaluation of serum lipase and amylase as diagnostic tests for acute pancreatitis
Laboratory testing of serum amylase and/or lipase levels are central to the diagnosis of acute pancreatitis (AP) as these tests are quick, cheap, reliable and perhaps the only objective criteria available at the bedside at the time of initial presentation. It is important to understand the physiology and biochemistry of these tests in order to get a clear grasp of their diagnostic utility. Lipa...
متن کاملLipase isoforms and amylase isoenzymes: assays and application in the diagnosis of acute pancreatitis.
Pancreatic juice and serum from patients with acute pancreatitis contain three enzymes that have lipolytic activity: L1 and L2, which are pancreatic isoenzymes or isoforms of lipase (EC 3.1.1.3), and L3, which is probably pancreatic carboxyl ester lipase, also known as cholesterol esterase (EC 3.1.1.13). These enzymes are readily separated electrophoretically on agarose and can be developed wit...
