Ferene(TM) (Diagnostic Chemicals LTD, Canada) is used as the chromogenic agent in an improved direct method for determining serum iron. The colour reagent contains hydroxylamine, a reducing agent stable in solution, and a protein solubilizer to avoid deproteinization. The interference of serum copper is eliminated by complexation with thiourea. Reliability of the method has been established by a separate study of the reaction parameters, replicate analysis and recovery experiments. The results obtained by the proposed method correlate well with results of atomic absorption spectroscopy. A fully automated application is also proposed using a centrifugal analyzer with starter dispenser.
