Routine Measurement of Serum Amylase in Acute Abdomen

Routine measurement of pleural fluid amylase is not indicated.

BACKGROUND The routine measurement of pleural fluid amylase is frequently recommended, but the cost-effectiveness of this procedure is unknown. METHODS To assess the utility of routine measurement of pleural fluid amylase in evaluating pleural effusions, we measured amylase, glucose, lactate dehydrogenase, and protein levels and blood cell counts in 379 patients undergoing thoracentesis durin...

Kinetic nephelometric procedure for measurement of amylase activity in serum.

We developed a kinetic procedure for determination of amylase activity in serum by use of nephelometric measurements. Light scattering from the substrate, a stable suspension of starch, is decreased as amylase hydrolyzes the starch to soluble fragments. Values obtained for serum amylase correlate closely with those determined by a method in which a starch-dye complex is used. Precision of the n...

Predictors of acute pancreatitis with low elevation of serum amylase

Background and aims Serum amylase is a traditional measure used to establish the diagnosis of acute pancreatitis (AP). The current study aimed to assess the predictors and clinical outcome of AP with low serum amylase. Methods All patients were divided into two groups, based on their serum amylase level within the first 2 days after hospital admission: group 1 (amylase ≥300 U/L) and group 2 (...
