Faecal Elastase Test – Pancreatic Function Test
Assess Pancreatic Digestive Function from Home
The Faecal Elastase Test is a simple, non-invasive stool test that checks for pancreatic elastase-1, an enzyme linked to how your pancreas helps with digestion.
Pancreatic elastase is released into your digestive tract and stays stable as it moves through your system. This makes it a helpful marker for checking how well your pancreas works.
Low faecal elastase levels can be linked to Exocrine Pancreatic Insufficiency (EPI), which means the pancreas is not making or releasing enough digestive enzymes. EPI can affect how your body digests and absorbs nutrients, and may cause symptoms like diarrhoea, bloating, stomach discomfort, greasy stools, and unexplained weight loss.
Our home test, analysed in a laboratory, gives you an easy way to learn about your pancreatic digestive function. You can then talk about your results with a healthcare professional if needed.
What Is Faecal Elastase?
Faecal elastase is a digestive enzyme produced by the pancreas and released into the intestine.
Unlike many other digestive enzymes, pancreatic elastase stays stable as it moves through your digestive system. By measuring how much is in your stool sample, we can get helpful information about how your pancreas is working.
A faecal elastase test does not check the overall health of your pancreas or diagnose a specific disease. It only shows how well your pancreas makes digestive enzymes.
Why Is Pancreatic Function Important?
The pancreas helps with digestion by making enzymes that break down food, so your body can absorb nutrients.
If your pancreas makes fewer enzymes, it can affect digestion and how well you absorb nutrients. This can cause symptoms like:
- Persistent or chronic diarrhoea
- Loose, oily or greasy stools
- Floating or difficult-to-flush stools
- Bloating and excessive gas
- Abdominal discomfort
- Unexplained weight loss
- Difficulty digesting fatty foods
- Nutritional deficiencies
- Fatigue associated with poor nutrient absorption
These symptoms can have many different causes, so they are not always due to pancreatic insufficiency.
Who Might Consider a Faecal Elastase Test?
You might consider a faecal elastase test if you have ongoing symptoms or if there are concerns about your pancreas not working properly.
Talk to your healthcare professional about testing if you have:
- Persistent digestive symptoms
- Chronic or recurrent diarrhoea
- Frequent bloating or abdominal discomfort
- Oily, greasy or difficult-to-flush stools
- Unexplained weight loss
- Concerns about nutrient absorption
- Nutritional deficiencies without an obvious explanation
Faecal elastase testing can also help when pancreatic insufficiency is suspected in people with certain medical conditions, such as:
- Chronic pancreatitis
- A history of pancreatic disease or surgery
- Cystic fibrosis
- Diabetes
- Certain gastrointestinal conditions
Having one of these conditions does not always mean you have pancreatic insufficiency. Your healthcare professional can help decide if testing is right for you.
What Does the Test Measure?
The test measures:
Pancreatic Elastase-1 in a stool sample
The amount of elastase found in your sample can show how well your pancreas is working.
Understanding Your Result
Results are commonly interpreted using ranges such as:
| Faecal Elastase Result |
General Interpretation |
|
>200 µg/g |
Generally considered within the normal range |
|
100–200 µg/g |
May indicate reduced pancreatic exocrine function and may require further assessment |
|
<100 µg/g |
More strongly suggestive of significant pancreatic exocrine insufficiency |
These ranges are just a general guide. Always consider your lab’s reference range and your personal situation when looking at your results.
A low result alone does not show the exact cause. Your healthcare professional will look at your symptoms, medical history, and other tests to help find the reason.
What Is Exocrine Pancreatic Insufficiency (EPI)?
Exocrine Pancreatic Insufficiency (EPI) happens when the pancreas does not make or release enough digestive enzymes to properly digest food.
Reduced digestive enzyme activity can particularly affect the digestion and absorption of fats and may contribute to:
- Greasy or oily stools
- Diarrhoea
- Bloating and abdominal discomfort
- Unintentional weight loss
- Nutritional deficiencies
- Fat-soluble vitamin deficiencies
EPI can be caused by several things, such as pancreatic disease, surgery on the pancreas, cystic fibrosis, or other medical conditions.
If EPI is suspected, your healthcare professional may suggest more tests and, if needed, treatment like pancreatic enzyme replacement therapy (PERT).

Do not stop prescribed medication unless advised to do so by a qualified healthcare professional.
Frequently Asked Questions
How reliable is a faecal elastase test?
Faecal elastase is a trusted lab marker for checking pancreatic exocrine function, especially when pancreatic enzyme insufficiency is suspected.
However, this test should not be used alone to make a diagnosis. Your results should be looked at together with your symptoms, medical history, and other clinical information.
What does a low faecal elastase result mean?
A low result may mean your pancreas is not working as well as it should. The lower the result, the more likely pancreatic insufficiency is, especially if you have ongoing symptoms.
A healthcare professional can help decide if you need more tests.
Can this test diagnose pancreatic cancer?
No.
A faecal elastase test checks how well your pancreas works, but it cannot diagnose or rule out pancreatic cancer, pancreatitis, or other pancreatic diseases.
If you have ongoing or worrying symptoms, talk to a healthcare professional instead of relying only on this test.
Can I take medication before the test?
Medication needs can be different for each person. Follow your test kit instructions and ask your healthcare professional if you are not sure.
Do not stop prescribed medication without medical advice.
Is the test suitable for children?
Faecal elastase testing can be done for children if pancreatic insufficiency is suspected. However, always talk to a healthcare professional first, especially if the child has ongoing symptoms, poor growth, or unexplained weight loss.
What happens if my result is low?
If your result is low, discuss it with a healthcare professional. They may suggest more tests or assessments based on your symptoms and medical history.
Does a normal result rule out all pancreatic problems?
No.
A normal faecal elastase result does not rule out all pancreatic or digestive problems. Always consider your symptoms and medical history too.
