58453-2Hemoglobin.gastrointestinal.lower [Mass/volume] in Stool by ImmunoassayActive

Term Description

A fecal immunochemical test (FIT) (also called an immunochemical fecal occult blood test or iFOBT) uses antibodies specific to the human globulin part of the Hemoglobin (rather than the heme part that Guiac tests target). Thus they do not react to animal, hemoglobin or myglobin) as found in meat , nor plant analogues, and drugs like Vitamin C do not effect the testing, so dietary adjustment is not needed. More important, globulin does not survive the enzymes of the upper digestive tract, so it is specific to lower GI bleeding-that is important to colon cancer screening. Different kit manufacturers have different requirements for repeats and timing, but most experts say you need samples from 2 different days for good results.
