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 ...
متن کاملProficiency testing matters.
Far too many laboratories consider proficiency testing just a necessary evil, little more than periodic pass–fail exercises we perform solely to meet regulatory requirements. In addition, too many of us belittle point-ofcare (POC) testing as a passing fad, a technology so inferior to what we use in our own laboratories that it hardly warrants our attention. Clearly, a report that combines these...
متن کاملProficiency testing in a medical-needs context.
Proficiency testing by State and Federal agencies is an ongoing activity of clinical laboratories and an occasional source of anxiety; strict statistical evaluations of "snapshot" laboratory values are inappropriate and medical-needs criteria should be used. The quality of laboratory results largely depends on available technology. Fortunately, for most of the common clinical chemistry analytes...

These suggestions are as follows: 1) Regular use of certified reference materials and/or internal quality control using secondary reference materials 2) Participation in interlaboratory comparison or proficiency testing programs 3) Replicate tests or calibrations using the same or different methods 4) Retesting or recalibration of retained items 5) Correlation of results for different character...
متن کاملWhen is a serum iron really a serum iron? The status of serum iron measurements.
Although serum iron determinations play an important role in the diagnostic process, the accuracy of routine methods is suspect. The poor performance of currently used methods is well documented in the quarterly College of American Pathologists survey reports. Compared with the 1990 method of the International Committee for Standardization in Haematology (ICSH), the 1978 ICSH Reference Method s...
