Calprotectin, Fecal - Stool Calprotectin
Fecal Calprotectin is an indicator of the presence of neutrophils in stool and is not specific for inflammatory bowel disease (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.
