The quantitative measurement of fecal lactoferrin released from leukocytes.

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).

Specimen Type: Random Stool

Collection Container: Sterile Container

Alternate Collection Container: Unpreserved Stool Transport Vial

Desired Specimen Volume: 1 g

1. Collect random stool in sterile container or unpreserved transport vial.

1. Do not contaminate outside of container or overfill container.
2.  Loose/watery stools are acceptable.
3. Ensure that no toilet tissue/sanitary materials are present in the submitted specimen. 

Transport to the laboratory refrigerated. 

• Nonfecal sample received (eg, serum, plasma, urine)
• Stool contaminated with urine
• Preserved stool received (eg, 10% formalin, sodium acetate formalin, or polyvinyl alcohol)

See patient report.

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.
