Test includes:
Qualitative detection of elevated levels of fecal lactoferrin
Immunochromatographic Assay
WBC, Fecal WBC, Fecal leukocytes, White Blood Cells, Stool lactoferrin, fecal lactoferrin, FLEIA
Clinical significance:
A positive test result indicates an increased level of fecal lactoferrin and warrants additional testing. Inflammation diarrheas are caused by pathogens such as Shigella, Salmonella, Camplyobacter jejunii, and Clostridium difficile. In inflammatory diarrheas fecal leukocytes are found in feces in large numbers. This test may not be appropiate for immunocompromised patients.
