Clinical Significance
Amylase is an amylolytic digestive enzyme produced by the exocrine pancreas and salivary glands. Amylase is increased in acute pancreatitis, pancreatic abscess or pseudocyst, pancreatic trauma, amyloidosis, pancreatic neoplasm, common-bile-duct obstruction, and after thoracic surgery. Increased amylase activity may be found in mumps parotitis and renal insufficiency.
