  • Blood Amylase
  • Urine Amylase

Amylase is a pancreatic enzyme that breaks down carbohydrates into sugars. Amylase levels can be measured in either blood or in urine (2 hour collection, or 24-hour collection). The levels are used to diagnose acute pancreatitis and to monitor your response to treatment. Stomach ulcers, intestinal obstructions, gall bladder disease, diabetic ketoacidosis, or mumps can also cause amylase levels to increase.

An amylase:creatinine clearance ratio provides a more specific diagnosis; a ratio that is equal to or more than 5 is a definite diagnosis of pancreatitis, while a ratio less than 5 is seen in diseases other than pancreatitis.
