Fecal Occult Blood/Transferrin Combined

The fecal occult blood test is a traditional routine examination item, which has important value for the diagnosis of digestive tract bleeding diseases. The test is often used as a screening index for the diagnosis of digestive tract malignant tumors in the population(especially in the middle-aged and the elderly). At present, it is considered that the colloidal gold method for fecal occult blood test, that is, determining the Human hemoglobin (Hb) in stools compared with the traditional chemical methods is of high sensitivity and strong specificity, and is not affected by the diet and certain drugs, which has been widely used. Clinical experience shows that the colloidal gold method still has certain false negative results by comparing with the results of digestive tract endoscopy, so the combined detection of transferrin in stools can improve the diagnostic accuracy.
