What Is Lipase in a Blood Test? Normal Range & What High Means
Also known as: Serum lipase, lipase blood test
Lipase is a digestive enzyme made mainly by your pancreas to help break down fats in food. Because the pancreas releases extra lipase into the blood when it's inflamed, the test is the main tool for detecting pancreatitis. A normal lipase level is roughly 10–140 U/L; a high lipase — often three or more times the upper limit — strongly suggests pancreatic inflammation.
Lipase normal range
| Category | Range (U/L) |
|---|---|
| Normal | 10–140 U/LRanges vary by lab |
| Elevated | > 140 U/L |
| Strongly suggests pancreatitis | > 3× upper limite.g. above ~420 U/L |
Reference ranges vary by laboratory. Use the range printed on your own report as the definitive comparison.
What high Lipase can mean
- Acute pancreatitis (the classic cause)
- Chronic pancreatitis flare
- Blocked pancreatic duct or gallstones
- Kidney disease (reduced clearance)
- Certain medications
What low Lipase can mean
- Low lipase is usually not clinically significant
- May occur with permanent pancreatic damage over time
What to do about an abnormal result
- High lipase with severe abdominal pain that radiates to the back needs urgent evaluation.
- Lipase is interpreted alongside symptoms and sometimes imaging of the pancreas.
- Mild elevations without symptoms are often rechecked and correlated with kidney function.

Frequently asked questions
What lipase level indicates pancreatitis?
A lipase level more than three times the upper limit of normal (often above roughly 420 U/L) strongly supports a diagnosis of acute pancreatitis, especially when paired with typical upper-abdominal pain. Diagnosis always combines the lab value with symptoms.
Can high lipase be caused by something other than the pancreas?
Yes. Kidney disease can raise lipase because the kidneys help clear it, and certain medications, bowel problems, and gallbladder disease can also elevate it. That's why your doctor interprets lipase in context rather than in isolation.
