A lipase test may also be referred to as a serum lipase or LPS.
What Conditions Can This Test Find?
The following symptoms can be a sign of pancreas inflammation:
The test may also be used to monitor your pancreas if you’ve already been diagnosed with acute (sudden, severe) or chronic (ongoing) pancreatitis. It can find out whether lipase levels are increasing or decreasing. It can also be used to find out whether a treatment is working well.
Sometimes, a lipase test will also be used to monitor other conditions including:
- Peritonitis (inflammation of the lining of your inner abdominal wall)
- Strangulated or infarcted bowel (bowel that has restricted blood supply)
- Pancreatic cyst
- Cystic fibrosis (an inherited disease in which thick mucus can damage organs)
- Crohn’s disease (inflammation of your digestive tract)
- Celiac disease (triggered by the protein gluten, your immune system attacks your small intestine)
How Do I Prepare?
If you have a lipase test scheduled ahead of time, you’ll need to fast.
You’ll likely be asked to stop eating or drinking anything other than water for 8 to 12 hours beforehand.
What Happens During a Test?
In a lipase test, a lab tech will take a small blood sample. He will likely put a band around your upper arm to help make your veins easier to find.
He will then insert a needle into one of your veins. After enough blood goes into a tube, the band will come off and he’ll take out the needle. He’ll put a bandage on where the needle went in.
Any Risks with Taking This Test?
You may feel a slight sting or pain during the blood draw. You may feel throbbing at the site afterwards.
The risks of getting blood drawn are minor and include:
What Do the Results Mean?
A high level of lipase in the blood indicates that you may have a condition affecting the pancreas.
Normal levels vary slightly between labs, so you and your doctor will look at the ranges given with your results to figure out how your lipase levels compare with the normal.
In acute pancreatitis, levels are often 5 to 10 times higher than the highest reference value. Other conditions can also cause slightly increased lipase levels, including:
Will I Take Any Other Tests?
Although doctors consider the lipase test the best one to diagnose acute pancreatitis, your doctor may also order a blood test for amylase, another enzyme that rises with pancreatitis.
