Model of the relationships between indicators or iron status and erythropoiesis. The model is based on the assumptions that hypoxia determines EPO production which in turn stimulates erythropoietic activity that drives the need for iron and corrects the hypoxia. Abbreviations: Hb, hemoglobin; EPO, erythropoietin; TfR, transferrin receptor; SF, serum ferritin.
