Test information: Calprotectin is a calcium binding protein produced in cells such as neutrophils and is released during inflammation. Faecal calprotectin is a biomarker of intestinal mucosal inflammation; In the presence of an inflammatory bowel disease (IBD) neutrophils influx into the intestinal lumen and release calprotectin which is then excreted in faeces. Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS) produce similar symptoms but have different treatment methods. The faecal calprotectin test can be used to help distinguish between the two conditions.
