Comments:
This test may be used to differentiate inflammatory bowel disease (IBD) from irritable bowel syndrome (IBS) and other functional disorders of the intestinal tract; may also be used for monitoring IBD activity.

Fecal Calprotectin is an indicator of the presence of neutrophils in stool and is not specific for IBD. Other intestinal ailments including GI infections and colorectal cancer can result in elevated concentrations of calprotectin. The diagnosis of IBD cannot be established solely on the basis of a positive calprotectin result. Patients with IBD fluctuate between active and inactive stages of disease. Calprotectin results may also fluctuate. GI bleeding of as much as 100 mL per day will increase the fecal calprotectin concentration by only 15 μg/g.
