The amylase test is a blood test. It measures the amount of an enzyme called amylase in the blood. Amylase is made by the pancreas and the salivary glands. It helps you digest starches (carbohydrates) in the food you eat.
Usually the test is done to check for problems with the pancreas. For example, this test may be done to see if you have pancreatitis, which is inflammation or swelling of the pancreas. The pancreas is an organ behind the stomach. It makes digestive enzymes and insulin. The digestive enzymes flow into the small intestine to help your body break down food. Insulin goes into the blood to control the level of sugar (glucose) in your blood.
This test may also be done if the salivary glands in your mouth are swollen or tender to check for infection or inflammation.
You may need to avoid taking certain medicines before the test because they might affect the test result. Make sure your healthcare provider knows about any medicines, herbs, or supplements that you are taking. Don't stop any of your regular medicines without first consulting with your healthcare provider.
