[The effect of transferrin detecting in digestive tract hemorrhage detection rate].

OBJECTIVE
To compare the sensitivity, the specificity and the anti-jamming of several excrement occult blood experimental techniques. To evaluate the effect of transferrin (Tf) in the excrement in the digestive tract hemorrhage detection rate.


METHODS
For 600 patients of clinical suspicious digestive tract hemorrhage, take their excrement specimen, using the chemical process (pyramidon semi-quantitative examination law) to detect hemoglobin (Hb), and using monoclonal antibody colloidal gold method to detect Hb and Tf.


RESULTS
Finally the hemoglobin chemical process (hereafter refers to as chemical process) to detect upper gastrointestinal hemorrhage with the positive rate 57.3%, and the detection of hemorrhage of lower digestive tract's positive rate is 44.8%; Hemoglobin monoclonal antibody colloidal gold method (hereafter refers to as colloid gold law) to examine upper gastrointestinal hemorrhage with a positive rate 60.4%, under examination hemorrhage with positive rate 77.6%; transferrin monoclonal antibody colloidal gold method (hereafter refer to as transferrin law) to examine upper gastrointestinal hemorrhage with a positive rate 82.3%, examination hemorrhage of lower digestive tract with a positive rate 66.4%; The union examination law (hemoglobin and transferrin to be detected twice, once positive that is positive) examines upper gastrointestinal hemorrhage the positive rate is 90.8%, hemorrhage of lower digestive tract's positive rate is 97.6%.


CONCLUSION
Excrement transferrin has the high detection rate in the upper gastrointestinal hemorrhage; Hb and the Tf combined examination may obviously raise the digestive tract hemorrhagic disease's positive detection rate.
