The effect of iron deficiency on whole blood viscosity in polycythaemic patients.
Iron deficiency leads to a significant increase in whole blood viscosity in polycythaemic patients. This can be corrected by simultaneous treatment with iron and venesection. In patients with polycythaemia secondary to hypoxia the haemoglobin concentration may be increased by treating coexisting iron deficiency, without altering the whole blood viscosity, thus increasing oxygen availability to the tissues. Values for whole blood viscosity can be derived from the peripheral blood Hb and MCH, allowing therapeutic decisions to be made on the basis of a simple haematological examination.
