What does the IRONWORKS protocol measure?

• A. Iron levels
• B. Ferritin
• C. Transferrin saturation
• D. Hemoglobin concentration

Answer: (A)

The IRONWORKS protocol is focused on the circulating iron in the blood—the serum iron level. This measures how much iron is actually available in the bloodstream for processes like red blood cell production at that moment. Ferritin reflects stored iron and can be elevated due to inflammation, while transferrin saturation combines serum iron with total iron-binding capacity and can fluctuate with several factors; both can be less reliable for guiding immediate iron therapy decisions in dialysis patients. Hemoglobin shows the end result of iron use (how many red cells you have) but doesn’t tell you how much iron is currently available. So, tracking serum iron gives a direct, actionable read on iron that helps tailor iron supplementation and avoid deficiency or overload.
