Clinical Info
Pleural fluids: Amylase measurement in pleural fluid is considered a useful test for detecting amylase-rich pleural effusions, which may be caused by exudative conditions associated with pancreatitis, esophageal rupture, malignancy, pneumonia, and liver cirrhosis. A ratio of pleural fluid amylase to a concurrent serum amylase >1 is defined as an amylase-rich pleural effusion. Peritoneal fluids and drainage fluids: Pancreatic damage causes extravasation of amylase from the exocrine cells into the peritoneal space. In cases of pancreatitis, fluid amylase should be at least several-fold times higher in fluid of pancreatic origin compared to concurrent serum amylase values. Pancreatic cyst fluid: Pancreatic cyst fluid amylase may aid in characterizing tumors and should be interpreted along with other clinical and laboratory information. References: 1.
