[Method of determining serum iron and iron-binding capacity without protein precipitation in very young children].

A modification of bathophenanthroline method is described. The method was used for diagnostics of anemia and in order to control the treatment of anemia in children of early ages. The method was checked by estimation of known concentrations of iron in solutions as well as by addition of known amounts of iron to blood serum. Standard deviations ranged from +/- 1.04 to +/- 6.5 and variation coefficient--from 0.5% to 10%. Normal values of iron content and of iron-binding capacity of blood serum, estimated by means of the modified method in 30 healthy children of early ages, did not differ from the corresponding data published in the literature.
