Lipase test
Pancreatitis - blood lipaseLipase 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 lipase in the blood.
Enzyme
Enzymes are complex proteins that cause a specific chemical change. For example, they can help break down the foods we eat so the body can use them....

A sample of blood will be taken from a vein.
Blood will be taken from a vein
Venipuncture is the collection of blood from a vein. It is most often done for laboratory testing.
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
- Cholinergic medicines
- Indomethacin
- Opiates (codeine, meperidine, and morphine)
- Thiazide diuretics
How the Test will Feel
You may feel slight pain or 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.
Why the Test is Performed
This test is done to check for disease of the pancreas, most often acute pancreatitis.
Acute pancreatitis
Acute pancreatitis is sudden swelling and inflammation of the pancreas.
Lipase appears in excessive amounts in the blood when the pancreas is damaged.
Normal Results
In general, normal results are 0 to 160 units per liter (U/L) or 0 to 2.67 microkat/L (µkat/L).
Normal value ranges may vary slightly among different labs. Some labs use different measurement methods. Talk to your provider about the meaning of your test results.
What Abnormal Results Mean
Higher-than-normal levels may be due to:
- Blockage of the bowel (bowel obstruction)
Blockage of the bowel
Intestinal obstruction is a partial or complete blockage of the bowel. The contents of the intestine cannot pass through it.

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
