Many diseases can cause hidden blood in the stool. In the early stages, gastrointestinal problems such as colon cancer, ulcers, polyps, colitis, diverticulitis, and fissures may not show any visible symptoms, only occult blood. Traditional guaiac-based method lacks sensitivity and specificity, and has diet-restrictions prior to testing.1,2
Tf is a type of β1 globulin, with a molecular weight of 77 KD, accounts for about 0.3% to 0.5% of the total plasma protein. It is mainly synthesized in liver, and the main function of the protein is to transport extracellular iron into cells through membrane receptor-mediated endocytosis. 3 As in the case of transferrin, serum Tf may be leaked into gastrointestinal tract during the course of bleeding. However, compared with transferrin, Tf is more stable .4, 5
The TF Transferrin Rapid Test Strip(Feces)is a rapid test to qualitatively detect low levels of Transferrin of fecal occult blood in feces. The test uses double antibody sandwich assay to selectively detect transferrrin of human occult blood in feces. In addition, unlike the guaiac assays, the accuracy of the test is not affected by the diet of the patients.
