The purpose of the Elastase test is to assess pancreatic function. Elastase is an enzyme produced by the pancreas and secreted into the small intestine to aid in food digestion. This test is commonly used to evaluate pancreatic insufficiency, particularly in cases where conditions such as exocrine pancreatic insufficiency (EPI) or chronic pancreatitis are suspected. The test measures the amount of elastase in stool, helping to determine pancreatic activity and its ability to produce digestive enzymes
