Absolute Iron Deficiency

Absolute iron deficiency is a pronounced reduction in iron storage. In cases of absolute iron deficiency we distinguish iron deficiency without anaemia (only reduced iron stores) and iron deficiency anaemia (empty iron stores plus low hemoglobin values).1, 5

Iron deficiency: Total body iron stores are low or exhausted. Patients may have symptoms such as fatigue, impairment of physical and mental performance and hair loss. Hemoglobin is normal, but serum ferritin levels and transferrin saturation (TSAT) are decreased.1, 5

Iron deficiency anaemia: at this stage, there is first of all a reduction in mean corpuscular volume (microcytosis), which corresponds to microcytosis, and/or a reduction in mean corpuscular haemoglobin concentration (hypochromia); in addition, haemoglobin, serum ferritin and transferrin saturation show abnormally low values.5
