Blood: biochemistry - iron

Synonym(s): Fe

Contributor(s): Annalisa Barrelet, Kathleen P Freeman, Frank Taylor

Overview

  • Transported in plasma bound to transferrin (beta-2 globulin).
  • Iron is stored as either ferritin or hemosiderin.
  • Synthesis of hemoglobin takes precedence over demands for other iron compounds so serum iron is more sensitive indicator of deficiency than MCV   Blood: mean corpuscular volume (MCV)  , MCH   Blood: mean cell hemoglobin (MCH)  , MCHC   Blood: mean corpuscular hemoglobin concentration (MCHC)  .
  • Serum [iron] only falls when storage iron depleted.
  • Severe iron deficiency (reduced intake and/or blood loss) can cause microcytic hypochromic anemia.
  • Measure either serum iron (plasma bound to transferrin) or serum total iron binding capacity (TIBC).
