What is Calprotectin?

Calprotectin is a protein biomarker that indicates the migration of neutrophils to the intestinal mucosa, occuring during inflammatory bowel disease (IBD). It is used to distinguish between IBD and non-inflammatory disorders and to monitor IBD disease activity. It helps improve patient care and reduce health care costs by screening out patients with Irritable Bowel Syndrome (IBS), thus preventing the need for unnecessary endoscopy procedures.
