ABSTRACT
Objectives: To clarify the diagnostic value of sTFR and its compound parameters sTFR/SF, sTFR/logSF in the differential diagnosis of IDA, ACD and CDID. Methods: Forty nine anemia patients were classified into IDA, ACD and CDID by clinical presentations and the laboratory results. The serum concentration of sTFR was detected by ELISA. The difference of sTFR, sTFR/SF, sTFR/logSF and routine parameters in the three groups and the correlation among sTFR and routine parameters were analyzed. Using ROC curve, the diagnostic value of these parameters in the differential diagnosis of the three diseases were compared. Results: The serum concentration of sTFR in the IDA, ACD and CDID were (50.8?8.2)nmol/L, (33.5?6.9)nmol/L and (22.7?9.9)nmol/L,respectively. The differences among three groups were significant( P
