Elastase stool test
Informed by recognized medical guidance
Overview
The elastase stool test is a simple test that measures the level of a protein called elastase in your stool (poo). Elastase is made by the pancreas, an organ behind your stomach that helps digest food. Low levels of elastase in stool can mean your pancreas is not working as well as it should to produce digestive enzymes.
Key facts
- A low elastase level suggests the pancreas is not making enough digestive enzymes.
- The test uses a small stool sample and is non-invasive (no needles or cameras).
- It can help diagnose exocrine pancreatic insufficiency (EPI), a condition where the pancreas doesn't release enough enzymes to digest fats and other nutrients.
Elastase stool testing is a common diagnostic tool, especially for people with symptoms like greasy stools, weight loss, or long-standing belly pain. The conditions it checks for are not extremely common, but they are seen more often in people with chronic pancreatitis, cystic fibrosis, or after certain surgeries.
It is typically used for adults who have symptoms of poor digestion. It is also used in children with cystic fibrosis or suspected pancreatic problems.
