Lactoferrin, Quantitative, Stool - 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. Fecal lactoferrin is a marker of intestinal inflammation, not a standalone diagnostic test for inflammatory bowel disease (IBD). Elevated concentrations should be interpreted in conjunction with clinical symptoms, endoscopic evaluation, histology and imaging studies. What Does Elevated Fecal Lactoferrin Mean? Elevated fecal lactoferrin is a marker of neutrophilic inflammation in the gastrointestinal tract. Lactoferrin is a glycoprotein released by activated neutrophils, making it highly specific for detecting intestinal inflammation 2. Collection Instructions: Collect a fresh random fecal specimen, no preservatives. If specimen is sent refrigerate, send immediately after collection. If specimen cannot be sent immediately, freeze specimen and send frozen. Lactoferrin is a protein in human milk and other bodily fluids. Learn about how doctors test for lactoferrin in stool samples and what the results mean. Learn what a fecal lactoferrin test measures, what high and normal results mean for gut inflammation, and how it compares with calprotectin. The concentration of lactoferrin in a stool sample is a direct reflection of the number of active neutrophils present in the digestive tract. Because the protein is stable and resistant to degradation by digestive enzymes, it provides a reliable, measurable marker of active inflammation. The Lactoferrin Quantitative Stool Test evaluates stool lactoferrin levels, supporting diagnosis of inflammatory bowel disease and digestive tract health.

An elevated level is an indicator of intestinal inflammation. The TechLab LACTOFERRIN SCAN assay is a quantitative enzyme-linked immunosorbent assay for measuring concentrations of human lactoferrin in feces. Briefly, polyclonal capture antibodies specific to human lactoferrin are immobilized on a 96-well plate.
