Lipase

Results continued...

The normal values listed here—called a reference range—are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.

Lipase1
Adults age 60 and younger:

10–140 units per liter (U/L) or 0.17–2.3 microkats/liter (mckat/L)

Adults older than age 60:

18–180 units per liter (U/L) or 0.30–3.0 mckat/L

High values

A high lipase level may be caused by:

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

What To Think About

  • You can have a high lipase level even when you do not have any problems with your pancreas.
  • A test for amylase, another enzyme produced by the pancreas, is often done at the same time as a test for lipase. Measuring both amylase and lipase sometimes can help determine the cause of a high amylase level. For more information, see the topic Amylase.
  • The lipase test is more accurate than the amylase test for diagnosing pancreatitis.
  • Other blood tests that may be done at the same time as a test for lipase include calcium, glucose, phosphorus, triglycerides, alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine. For more information, see the topics Calcium in Blood, Blood Glucose, Alanine Aminotransferase, Blood Urea Nitrogen, and Creatinine and Creatinine Clearance.
