Clinical Use  An in vitro diagnostic aid to distinguish patients with active inflammatory bowel disease (IBD) from those with inactive IBD, as well as from noninflammatory irritable bowel syndrome (IBS). Fecal lactoferrin is sensitive and specific for detecting inflammation in chronic IBD. This noninvasive test may be useful in screening for inflammation in patients presenting with abdominal pain and diarrhea.

Special Handling  Do NOT contaminate outside of container; do NOT overfill container. Loose/watery stools are acceptable. Ensure that no toilet tissue/sanitary materials are present in the submitted specimen. Ship refrigerated at 2(degrees)C to 8(degrees)C.
Lab Notes  Causes for Rejection: Nonfecal sample received (eg, serum, plasma, urine); stool contaminated with urine; preserved stool received (eg, 10% formalin, sodium acetate formalin, or polyvinyl alcohol)

Limitations  Test may not be appropriate in immunocompromised persons, patients with a history of HIV and/or hepatitis B and C, patients with a history of infectious diarrhea (within six months), and patients having had a colostomy and/or ileostomy within one month. Fecal lactoferrin concentration should not be interpreted as absolute evidence of the presence of a gastrointestinal illness. Other intestinal ailments, including many gastrointestinal infections and colorectal cancer, often result in elevated levels of fecal lactoferrin. Prediction of active and inactive disease should be based on a completeevaluation of the patient that may also include multiple fecal lactoferrin level determinations
