[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.
