Lipase Tests
Lipase Tests: Everything You Need to Know
Lipase tests are diagnostic tests that measure the level of the enzyme lipase in blood or body fluids such as urine, saliva or fluid around the pancreas. This enzyme helps to break down dietary fats into molecules that the body can absorb.
Why Do Lipase Tests?
Lipase tests are done to help diagnose certain digestive disorders and diseases such as:
- Acute pancreatitis
- Chronic pancreatitis
- Gallstones
- Cancer of the pancreas
- Cystic fibrosis
- Bacterial infections
When Do Lipase Tests?
Lipase tests are typically conducted when a person is showing signs and symptoms of a digestive disorder or disease, such as abdominal pain, nausea, and vomiting. Other times when a doctor may order a lipase test is when other laboratory tests indicate that pancreatitis is present.
How to Prepare for Lipase Tests?
Generally there is no preparation necessary for a lipase test, however, it is important to inform your doctor of any medications you may be taking as this may affect the results of the test.
Types of Lipase Tests
The two most common lipase tests used are amylase and lipase tests. Amylase is an enzyme that breaks down carbohydrates while lipase breaks down dietary fats. The levels of each of these enzymes in the blood indicate how well they are functioning in the body.
How are Lipase Tests Conducted?
For lipase tests, a blood sample is taken usually from a vein in the arm. The blood is then sent to a laboratory where it is analyzed to determine the level of lipase present in the sample.
What Are the Risks of Lipase Tests?
Lipase tests are generally considered safe with minimal risk of complications. The most common risk associated with the test is pain and/or bruising at the site of injection.
What is the Normal Range of Lipase Tests?
The normal range for lipase tests is typically between 10 and 60 U/L. However, the normal range may vary depending on laboratory and the type of test being performed.
What Does an Abnormal Lipase Test Result Mean?
An abnormal lipase test result usually indicates the presence of a digestive disorder or disease. The doctor will use the results of the lipase test, along with other diagnostic tests, to determine the cause of the abnormal test results.
