Support test for the diagnosis of pancreatic insufficiency

Automated CLIA assay for the quantitative determination of fecal pancreatic elastase in human stool specimens on LIAISON® analyzers.

Indications for use


Diagnosis of exocrine pancreatic insufficiency (PEI)

Target patient

Adults and children with a suspected malfunction of the pancreas

Use area


LIAISON® Elastase-1 for accurate diagnosis of gastrointestinal diseases - Diasorin


Treatment of maldigestion starts with the right diagnosis

Pancreatic insufficiency is the inability of the exocrine pancreas to produce and/or transport enough digestive enzymes to break down food in the intestine and facilitate absorption of nutrients. It typically occurs because of progressive pancreatic damage that may be caused by recurrent acute pancreatitis or by chronic pancreatitis due to a variety of conditions. Failure in any of the digestive metabolic steps may be the result in pancreatic exocrine insufficiency (PEI). Current methods for evaluating digestion, such as fecal fat quantification and the 13C-mixed triglycerides test are complicated and often need long execution times. LIAISON® Elastase-1, is a fully automated CLIA assay that simplifies testing and reduces the number of required steps.

How it works

LIAISON® Elastase-1 allows the quantitative determination of fecal elastase-1 in stool samples. 

Easy handling of stool sample


Easy handling of stool sample

The use of the LIAISON® Q.S.E.T. Device Plus reduces the preparation steps of the extracted stool samples and allows the operator to easily handle the stool, thus saving time.


30 minutes to results

Save time and unnecessary testing by quickly identifying exocrine pancreatic insufficiency (PEI).

Non-invasive LIAISON® test by Diasorin for the diagnosis of Pancreatic Exocrine Insufficiency

Why use LIAISON® Elastase-1

A specific non-invasive method for PEI diagnosis

Reliable diagnostic solution

Safely diagnose PEI while preventing the patient from further invasive investigations.

Easy-to-use diagnostic solution

The LIAISON® Q.S.E.T. Device Plus is ready-to-use and improves the pre-analytical process. This tool offers a secure and simple handling of the feces. 

Improved sensitivity and specificity

LIAISON® Elastase-1 has a better sensitivity and specificity than chymotrypsin testing* (Doi: 10.3748/wjg.14.3149), and unlike other tests it is non-invasive and does not require patient to follow a special diet or discontinue pancreatic enzyme replacement therapy.  

To be used on

Designed for both specialty and routine tests, LIAISON® XL and LIAISON® XS immunoassay analyzers help your laboratory handle multiple patients and tests simultaneously. LIAISON® systems are trustworthy, intuitive and deliver automated continuous operation with minimal user intervention. The result is reduced turnaround time, optimal cost management and unmatched growth potential.
