Why is iron status monitored in dialysis patients?

• A. To prevent iron deficiency and optimize ESA response; ferritin and transferrin saturation are used
• B. To check infection risk
• C. To monitor hydration
• D. To adjust potassium levels

Answer: (A)

Iron is needed for making red blood cells, and in dialysis patients anemia is commonly treated with ESAs. Monitoring iron status with ferritin and transferrin saturation helps ensure there is enough iron available for erythropoiesis and to optimize ESA response. Ferritin indicates stored iron, while transferrin saturation reflects circulating iron that can be used for red blood cell production. Because ferritin can be elevated with inflammation, clinicians look at both values together to decide whether IV iron is needed and how to adjust ESA dosing. The aim is to prevent iron deficiency, avoid iron overload, and improve anemia management. Monitoring iron status is not primarily used to assess infection risk, hydration status, or potassium levels.
