Clinical Information

Amylases degrade complex carbohydrates (starches) into simple sugars. Two isoenzymes, pancreatic and salivary, are found in serum. Serum pancreatic amylase should always be interpreted in a context of total amylase to determine the relative contribution of salivary and pancreatic isoenzymes.

 

Imaging tests have become the diagnostic tests of choice for diagnosing pancreatitis. Pancreatic isoamylase may be used as an adjunct to totally serum amylase, serum lipase, and imaging tests.

Interpretation

Increased concentrations of pancreatic amylase isoenzymes in a context of elevated total serum amylase may indicate pancreatitis.
