The LACTOFERRIN CHEK® test is an enzyme immunoassay (ELISA) used to detect elevated levels of lactoferrin, a marker of fecal leukocytes and an indicator of intestinal inflammation. The test can be used as an in vitro diagnostic aid to help identify patients with active inflammatory bowel disease (IBD) and rule out those with active irritable bowel syndrome (IBS), which is noninflammatory.
