Test Overview
Test Methodology

ELISA

Test Usage

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.

Reference Range *

Normal: >200 mcg Elastase/g; Moderate to slight exocrine pancreatic insufficiency: 100 - 200 mcg/g Elastase; Severe exocrine pancreatic insufficiency: <100 mcg Elastase/g.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

A watery, diarrheal stool is not recommended for this test as some dilutions during the assay may give lower E1 concentrations than are actually present.
