Pancreatic function
Pancreatic Elastase ELISA
A quantitative ELISA for pancreatic elastase-1 — the laboratory reference method.
Clinical use
Quantifies exocrine pancreatic function in the lab, for diagnosis and grading of pancreatic insufficiency.
Highlights
- Quantitative ELISA — normal 200 to >500 µg E1/g stool; 100–200 µg = moderate to mild exocrine pancreatic insufficiency; under 100 µg = severe. Measuring range 15–500 µg E1/g
- Enzyme substitution therapy does not influence the result — the assay is specific to human pancreatic elastase 1
