Test Code LAB6091 Calprotectin

Intended Use

The DiaSorin LIAISON® Calprotectin Assay is an in vitro diagnostic chemiluminescent immunoassay (CLIA) intended for the quantitative measurement, in human stool, of fecal calprotectin, a neutrophilic protein that is a marker of mucosal inflammation. The LIAISON® Calprotectin Assay can be used as an aid in the diagnosis of inflammatory bowel diseases (IBD), specifically Crohn’s disease and ulcerative colitis, and as an aid in differentiation of IBD from irritable bowel syndrome (IBS). Test results are to be used in conjunction with information obtained from the patients’ clinical evaluation and other diagnostic procedures.

Methodology

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