Test Information

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 complete evaluation of the patient that may also include multiple fecal lactoferrin level determinations.

Reference Range Information
Baseline (normal): 0.00−7.24
Elevated: >7.24
Interpretation
An elevated result is indicative of the presence of fecal lactoferrin, a marker of intestinal inflammation. A normal result does not exclude the presence of intestinal inflammation.
