Comments:
The Fecal Lactoferrin test detects elevated levels of lactoferrin released from fecal leukocytes as a marker of intestinal inflammation. This test is not valid for infants who are breast feeding or mixed feeding as breast milk contains high levels of lactoferrin and will give a false positive result.
Rejection Criteria:
Specimen in transport medium (C&S medium) or preserved in 10% formalin, MF, SAF, PVA, or other fixative; delayed transport.
