Role of Soluble Transferrin Receptor - An Iron Marker in Hemodialysis Patients.

Background: Iron status assessment is crucial in end-stage renal disease hemodialysis (ESRD-HD) patients because iron deficiency may cause unresponsiveness to erythropoiesis-stimulating agent. Soluble transferrin receptor (sTfR) is a potential iron marker that is not influenced by inflammation, and the results among studies are still conflicting. This study evaluated the role of sTfR in determining iron deficiency in ESRD-HD patients.
