Serum iron and proficiency testing: a dilemma.
We present and discuss observations regarding the results of the serum iron determination as seen in various surveys. The reference method proved to score different in our hands judging on the performance in the Dutch and German quality assessment schemes. Furthermore, it is clear and frustrating that these scores, representing the most accurate results, are becoming more and more labeled "out of acceptable range".
