利用室间质评回报结果对临床生化检验常规项目不确定度评定的方法探讨
Method study on evaluation of measurement uncertainty in clinical biochemical routine detection items by return report results of external quality assessment
摘要
Abstract
Objective To adopt the type A and B evaluation methods to study the evaluation method of the measurement uncertainty of clinical biochemical routine test items .Methods The variations of within-run and be-tween-run ,the uncertainty of the standard substance provided by manufacturers and the data of the external quality assessment(EQA ) during 2010 - 2012 were adopted to calculated the combined and expanded uncertainties of the main routine clinical biochemistcal test items .Results Among the components constituting the uncertainty ,the sys-tematic bias contributed most to the measurement uncertainty ,followed by the imprecision component and the calibra-tor component .The measurement uncertainties of TBil ,DBil ,BUN and phosphorus were higher ;TG ,UA ,CK and Mg reached the more ideal level ,and the other items were qualified .Conclusion This evaluation method is simple ,easy to operate and convenient to intuitively express the influence degree of different factors on the detection results ,but its practical application in clinic needs more exploration .关键词
