Changes in iron metabolism parameters in iron deficiency diseases.

	Serum Iron (umol/L)	Ferritin Concentration (ug/L)	Iron Transferrin Saturation (%)	Total Iron-Binding Capacity (umol/L)	Serum Soluble Transferrin Receptor Concentration (mg/L)
Normal values	10–30	10–200 in women; 15–400 in men	17–44%	40–80 in women; 45–75 in men	1.9–4.4 in women; 2.2–5 in men
Iron deficiency anemia	↓	17–44%	↓	↑	↑
Latent iron deficiency	Normal/↓	40–80 in women; 45–75 in men	Normal/↓	↑	↑
Iron deficiency anemia refractory to iron therapy	↓	1.9–4.4 in women; 2.2–5 in men	↓	↑	↑
Anemia of chronic diseases	↓	10–30	↓	↓	Normal

↓—reduced level; ↑—elevated level.
