Lactoferrin is a marker for fecal leukocytes and a positive result is an indicator of intestinal inflammation. This elevation may be caused by acute infectious colitis or active inflammatory bowel disease (IBD). The test may not be appropriate in immunocompromised persons. In addition, this test is not FDA cleared for patients with a history of HIV and/or hepatitis B and C, patients with a history of infectious diarrhea (within 6 months), and patients having had a colostomy and/or ileostomy within 1 month.
