The effect of transferrin detecting in digestive tract hemorrhage detection rate / 中国医疗器械杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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%.</p><p><b>CONCLUSION</b>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.</p>
