Test Summary
The lactoferrin IBD-scan is a quantitative enzyme linked immunosorbent assay for measuring concentrations of fecal lactoferrin, a marker for leukocytes. An elevated level is an indicator of intestinal inflammation. The test can be used as an in vitro diagnostic aid to distinguish patients with active Inflammatory Bowel Disease (IBD) from those with non-inflammatory irritable bowel syndrome (IBS).
