Review reveals iron-restricted erythropoiesis in blood loss anemia, highlighting the need for intravenous iron and novel cellular indices.

Key Points

To examine the interplay between erythropoietin therapy, iron availability, and erythropoiesis, and to evaluate modern diagnostic markers and treatment strategies for iron-restricted red blood cell production.
Synthesized clinical evidence on iron dynamics in blood loss anemia with and without recombinant human erythropoietin therapy.
Evaluated the diagnostic utility of serum ferritin, transferrin receptor assays, and automated reticulocyte indices in renal dialysis and chronic disease cohorts receiving iron interventions.
Significant blood loss and erythropoietin therapy induce iron-restricted erythropoiesis even in the presence of adequate storage iron and oral supplementation.
Intravenous iron administration elicits positive hematologic responses in dialysis patients with serum ferritin levels as high as 400 μg/L, demonstrating the inadequacy of traditional storage iron markers.
Automated erythrocyte and reticulocyte indices reliably detect functional iron deficiency, whereas serum erythropoietin and transferrin receptor assays remain largely confined to research settings.
