臨床化学精度調査のデータ処理

抄録

For evaluating clinical chemistry control survey results, following parameters are introduced: proficiency of accuracy, proficiency of precision, relative accuracy and relative precision for each laboratories, and general evaluation indicators for evaluating the proficiency level of participant laboratories.These parameters are calculated based on an allowable error function E (x), which consists of statlonary error and proportional error of the assay.The parameters were applied to Kyushu Control Survey and Nagasaki Control Survey results, and were useful to detect individual laboratory error and progress of proficiency in Successive years.
