19 Most of the transferrin-bound iron is incorporated into hemoglobin. Excess iron not needed for hemoglobin synthesis is stored in tissues as ferritin or hemosiderin. Transferrin saturation indicates iron availability at the erythroid marrow. When iron depletion is occurring, serum transferrin levels increase. However, when iron stores are exhausted, transferrin levels fall.
Ferritin levels correlate with total body iron stores.
