Lipase is a protein (enzyme) released by the pancreas into the small intestine. It helps the body absorb fat. This test is used to measure the amount of the lipase in the blood.
How the test is performed
A sample of blood will be taken from a vein.
How to prepare for the test
Do not eat for 8 hours before the test.
Your health care provider may ask you to stop taking medicines that may affect the test, such as:
Birth control pills
How the test will feel
You may feel slight pain on a sting when the needle is inserted to draw blood. There may be some throbbing at the site after the blood is drawn. Veins and arteries vary in size so it may be harder to take a blood sample from one person than another.
