Why get tested?

To diagnose pancreatitis or other pancreatic disease

When to get tested?

If you have symptoms of a pancreatic disease, such as severe tummy pain, fever, loss of appetite or nausea

Sample required?

A blood sample drawn from a vein in the arm

Test preparation needed?

None

What is being tested?

Lipase is an enzyme manufactured primarily by the pancreas. It is released into the digestive tract to help digest fatty foods. It is also important in maintaining cell permeability, that is, allowing the cell wall to let nutrients easily flow in and to let waste easily flow out.

How is the sample collected for testing?

A blood sample is taken by needle from a vein in the arm.

Is any test preparation needed to ensure the quality of the sample?

No test preparation is needed.

The Test

How is it used?

The blood test for lipase is used to help diagnose pancreatitis (inflammation of the pancreas) and other pancreatic diseases. It is also used to a lesser extent in the diagnosis and follow-up of cystic fibrosis, coeliac disease and Crohn's disease.

When is it requested?

A lipase test may be used if you show symptoms of a pancreatic disorder, such as severe abdominal pain, fever, loss of appetite or nausea.

What does the test result mean?

Looking for reference ranges?

Normal values for lipase depend on the test used to measure it. In acute pancreatitis, lipase levels are very high, often 2 to 5 times normal. Slightly high lipase values may occur in other conditions such as kidney disease, salivary gland inflammation, or peptic ulcer disease. Occasionally lipase is high due to a tumour (cancer). A rapid and sharp rise of lipase in the blood within hours after the beginning of an attack, and a decline after about 4 days, usually indicates acute pancreatitis.

Is there anything else I should know?

In acute pancreatitis, the changes seen in lipase levels are usually similar to levels of another enzyme called amylase, but remains elevated longer (for 5 to 7 days).

Lipase and amylase are sometimes used together to diagnose acute pancreatitis. Both may also be used to monitor chronic pancreatitis. Both may be moderately elevated in chronic pancreatic disease but levels may fall if the cells that produce amylase and lipase in the pancreas become damaged or destroyed.

Drugs that may increase lipase levels include codeine, indomethacin and morphine.

Common Questions

What are the long-term consequences of pancreatitis?

Acute pancreatitis usually causes no long term damage and often no further problems develop. Chronic pancreatitis may follow a series of acute attacks, but is almost always due to many years of alcohol abuse. It causes permanent pancreatic damage with scarring and calcium deposits. Some people develop diabetes. There is often difficulty digesting foods, especially fats, causing abdominal pain, pale, bulky, greasy stools and loss of weight.

What are the treatment options for pancreatitis?

Treatment depends upon the symptoms. If they are absent or mild, there may be no treatment; if they are more severe, your doctor may suggest 'resting the pancreas' using a range of options, from not eating solid foods to fasting combined with intravenous (IV) fluid replacement for several days to a few weeks (usually requiring admission into hospital). This use of medicines and surgery may also be considered for patients with severe symptoms. Sometimes you may need pain management medicines. Nutritional support, such as low-fat diets and frequent small meals, may help relieve symptoms. Oral pancreatic enzyme replacement is another possible choice.

Do elevated lipase levels always mean I have a pancreatic condition?

In pancreatitis, the lipase rises quickly but begins to drop in about 4 days. In other conditions, the rise is usually not as great and the level is maintained for a longer period. Your doctor is the best one to determine if you have a pancreatic disorder based on your symptoms, medical history and test results.
