Performing Laboratory Information
Performing Location Analytical Time​Methodology/Instrumentation
LabCorp ​4-6 days​Enzyme-linked immunosorbent assay (ELISA) based upon a monoclonal antibody-based detection system specific for pancreatic elastase-1 (PEL-1)
Reference Lab
LabCorp of America
Test Information
The polyclonal antibodies used in this assay are specifically directed against defined sequences of the human pancreatic elastase molecule. The enzyme stability is remarkably high despite its proteolytic activity, as elastase is found in feces in about a sixfold concentration as in pancreatic fluid. The determination of enzyme concentration in feces reflects the exocrine secretory capacity of the pancreas.
Reference Range Information
• Normal: >200 μg elastase/g fecal material
• Moderate pancreatic insufficiency: 100−200 μg elastase/g fecal material
• Severe pancreatic insufficiency: <100 μg elastase/g fecal material
