What does the Digestion and Absorption Markers (pancreatic elastase-1 and products of digestion) test measure?

Q: What is the reference range for Digestion and Absorption Markers (pancreatic elastase-1 and products of digestion)?

The standard reference range for Digestion and Absorption Markers (pancreatic elastase-1 and products of digestion) is Pancreatic elastase-1: >200 µg/g normal (100–200 moderate, <100 severe exocrine pancreatic insufficiency); products of digestion (fat, fibres, carbohydrates) reported semi-quantitatively. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Digestion and Absorption Markers (pancreatic elastase-1 and products of digestion) (Digestion/Absorption) is a clinical biomarker used in gastrointestinal assessment. Pancreatic elastase-1 is a pancreas-specific protease that resists intestinal degradation, so its faecal concentration reflects exocrine pancreatic output. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Digestion and Absorption Markers (pancreatic elastase-1 and products of digestion)?

Pancreatic elastase-1 is a pancreas-specific protease that resists intestinal degradation, so its faecal concentration reflects exocrine pancreatic output. Microscopic products of digestion reflect the completeness of luminal digestion and absorption.

Why is Digestion and Absorption Markers (pancreatic elastase-1 and products of digestion) measured?

Faecal pancreatic elastase-1 is a validated, established non-invasive marker of exocrine pancreatic insufficiency. The microscopic products-of-digestion markers are qualitative and operator-dependent, and are interpreted supportively rather than diagnostically.
