Copper interference in the determination of iron in serum using ferrozine.
Random samples of sera were analysed for copper and iron. Based on the data presented in this paper and substantiated by other workers, the ferrozine method for the determination of serum iron is the most sensitive method currently available, provided the interference due to copper is effectively eliminated.
