[Determination of blood iron using an electrochemical detector: comparison of methods and study of normal values in children].

Electrochemical detector offers a rapid, accurate, precise and inexpensive micromethod for measuring iron in serum, in practise 50 microliters of serum is pipetted into the electrochemical cell and 60 seconds after the serum iron concentration is displayed digitally in mcg/dl. Day to day precision is 1.2%, the linearity is +/- 2% over range 0-1000 mcg/dl. Normal value in pediatric patients are 42-94 mcg/dl.
