Iron metabolism in polycythaemia rubra vera and secondary polycythaemia

Serum iron concentration, serum iron binding capacity and saturation coefficient were assayed in polycythaemia rubra vera and secondary polyglobulia. In the exacerbation stage of polycythaemia rubra, significantly lower Se Fe and SC values were found while in the remission stage and in secondary polyglobulias these values did not differ from those of the normal control.
