What is this test?
Pancreatic elastase is an enzyme made by the pancreas and released into the digestive tract. This qualitative stool test detects its presence and may be used to help assess pancreatic function.
Why might I need this test?
Your clinician may order this test if you have symptoms suggesting pancreatic insufficiency, such as persistent diarrhea, oily or foul-smelling stools, unexplained weight loss, or poor nutrient absorption. It may also be used when monitoring conditions that affect the pancreas.
How is the test performed?
A small stool sample is collected and tested in the laboratory for pancreatic elastase. The result is reported as positive or negative rather than as a specific numerical measurement.
How do I prepare for the test?
Follow your clinician's instructions about which stool sample to submit and when to collect it. Tell the laboratory if you are taking medicines that may affect digestion or pancreatic function, and do not stop prescribed medicines without medical advice.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result generally indicates that pancreatic elastase is present in the stool. An unexpected negative result may suggest reduced pancreatic enzyme output or pancreatic insufficiency, but it can also occur with sample problems or certain digestive conditions, so results should be interpreted alongside symptoms and other testing.
Short name
Stool Pancreatic Elastase
