The diagnostic power of the transferrin receptor-ferritin (TfR-F) index for identification of iron responsiveness in long-term hemodialysis (HD) patients compared with the routine markers recommended by the current US and European guidelines was appraised. ⋯ TfR-F index is superior to routine tests for predicting response to IVFE supplementation in long-term HD patients. Our study indicates that TfR-F index is a new and surrogate marker to estimate body iron stores and guide IVFE therapy for long-term HD patients.
