Hb, Hemoglobin; MCV, median corpuscular volume; FEP, free erythrocyte protoporphyrin; SFe, serum Fe; TIBC, total Fe binding capacity; TS, transferrin saturation; SF, serum ferritin. a Values are expressed as geometric means and ranges ±1 SD. b Cut-off points to define iron status [37]. c Cut-off points to define SF [38].
