Amylase is an enzyme produced mainly in the pancreas and salivary glands and in small amounts in the liver and fallopian tubes. Amylase participates in the digestion of complex carbohydrates into simple sugars. In clinical practice, blood amylase and urine amylase tests are valuable in diagnosing acute pancreatitis, chronic pancreatitis, the stage of pancreatitis and in differential diagnosis with other internal and digestive diseases.
