Bg. Blijenberg et al., SERUM IRON AND PROFICIENCY TESTING - A DILEMMA, European journal of clinical chemistry and clinical biochemistry, 31(4), 1993, pp. 233-237
We present and discuss observations regarding the results of the serum
iron determination as seen in various surveys. The reference method p
roved to score different in our hands judging on the performance in th
e Dutch and German quality assessment schemes. Furthermore, it is clea
r and frustrating that these scores, representing the most accurate re
sults, are becoming more and more labeled ''out of acceptable range''.
