LIAISON® Calprotectin

When patients present with symptoms of bowel disease, a correct diagnosis becomes a challenge.

LIAISON® Calprotectin is a non-invasive method for a differentiated diagnosis  and for an assessment of IBD disease activity.

Indications for use


Differentiate IBS (Irritable Bowel Syndrome) from IBD (Inflammatory Bowel Disease)

Target patient

Adults and children with suspicion of IBD

Use area


Immunoassays or the detection of Calprotectin - LIAISON® Diasorin

Differentiate IBS from IBD with a single test

Diasorin offers a complete solution for the fast, accurate and automated detection of Calprotectin: LIAISON® Q.S.E.T. Device Plus automatic extraction tubes and LIAISON® Calprotectin CLIA assay.
Calprotectin is secreted by neutrophils, which in case of inflammation of the intestine are recalled in this area and the concentration of Calprotectin therefore increases in the stool. Because Calprotectin is resistant to enzymatic degradation, it can be easily measured in feces but must be extracted from a native stool sample. The LIAISON® Calprotectin assay, which can be automatically run on the LIAISON® analyzer family, simplifies the detection of Calprotectin to speed IBD diagnosis.

How it works

LIAISON® Calprotectin allows the quantitative determination of Calprotectin 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.


35 minutes to results

Save time and unnecessary testing by quickly identifying Calprotectin.


Non-invasive method for patient

LIAISON® Calprotectin is a CLIA sandwich assay that uses 2 monoclonal antibodies for capture and detection of Calprotectin.
