Pancreatic Elastase (PE) in Stool

Small Bowel Biopsy
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. Pancreatic enzyme supplementation therapy should be discontinued prior to sample collection.
