Faecal elastase
Informed by recognized medical guidance
Overview
A faecal elastase test measures the amount of an enzyme called elastase in your stool (poo). This enzyme is made by your pancreas and helps you digest food. Low levels can mean your pancreas isn't working well enough to make the enzymes you need for digestion.
Key facts
- The test uses a small sample of your stool to check pancreatic function.
- Low faecal elastase suggests pancreatic exocrine insufficiency (PEI).
- It is a reliable, non-invasive test that does not require any special preparation.
This test is commonly performed when a person has symptoms of poor digestion, such as fatty, foul-smelling stools, unexplained weight loss, or ongoing bloating.
It affects people of all ages who may have a problem with their pancreas, including those with chronic pancreatitis, cystic fibrosis, or after pancreatic surgery.
