Pancreatic elastase (PE) is not degraded during intestinal transit and the concentration of PE in a stool sample reflects exocrine pancreatic function. This assay allows the diagnosis or exclusion of pancreatic exocrine insufficiency, which can be caused by chronic pancreatitis, cystic fibrosis, pancreatic tumor, cholelithiasis or diabetes mellitus.
Normal: >200 mcg Elastase/g; Moderate to slight exocrine pancreatic insufficiency: 100 - 200 mcg/g Elastase; Severe exocrine pancreatic insufficiency: <100 mcg Elastase/g.
