HIE Multimedia - Amylase - blood

Amylase is an enzyme that helps digest carbohydrates. It is made in the pancreas and the glands that make saliva. When the pancreas is diseased or inflamed, it releases increased amounts of amylase into the blood. A test can be done to measure the level of this enzyme in your blood. Amylase may also be measured with a urine amylase test.
