目的:对上海市临床实验室2012年度室间质量评价(EQA)肾功能指标检测结果进行分析,了解上海市肌酐(Cr)、尿酸(UA)、尿素(UN)检测的现状,为标准化进程提供实验数据。方法通过向上海地区实验室发放10个批次不同浓度的质评物进行常规化学的EQA,将Cr、UA、UN按10套检测仪器分组分析。EQA数据分析按结果剔除离群值后计算各组的均值(x珋)、标准差(s)、变异系数(CV)。结果 EQA结果分析中,Cr、UA、UN不同检测仪器CV范围分别为1.30%~12.73%、1.06%~6.78%、1.55%~8.79%。Cr 进口1组实验室间的变异情况较好,检测质评物(46~574)μmol/L CV范围为1.70%~5.15%。UA进口3组实验室间的变异情况较好,检测质评物(132~550)μmol/L CV范围为1.49%~2.19%;UN进口2组实验室间的变异情况较好,检测质评物(3.15~18.13)mmol/L CV范围为1.55%~2.74%。结论就项目而言,上海市临床实验室Cr的检测性能还有待于进一步提高。就仪器而言,国产检测仪器的性能有待进一步提高。仍需通过开展实验室全面质量管理,逐步达到检测结果的互认,为临床提供可靠的诊疗依据。
目的:對上海市臨床實驗室2012年度室間質量評價(EQA)腎功能指標檢測結果進行分析,瞭解上海市肌酐(Cr)、尿痠(UA)、尿素(UN)檢測的現狀,為標準化進程提供實驗數據。方法通過嚮上海地區實驗室髮放10箇批次不同濃度的質評物進行常規化學的EQA,將Cr、UA、UN按10套檢測儀器分組分析。EQA數據分析按結果剔除離群值後計算各組的均值(x珋)、標準差(s)、變異繫數(CV)。結果 EQA結果分析中,Cr、UA、UN不同檢測儀器CV範圍分彆為1.30%~12.73%、1.06%~6.78%、1.55%~8.79%。Cr 進口1組實驗室間的變異情況較好,檢測質評物(46~574)μmol/L CV範圍為1.70%~5.15%。UA進口3組實驗室間的變異情況較好,檢測質評物(132~550)μmol/L CV範圍為1.49%~2.19%;UN進口2組實驗室間的變異情況較好,檢測質評物(3.15~18.13)mmol/L CV範圍為1.55%~2.74%。結論就項目而言,上海市臨床實驗室Cr的檢測性能還有待于進一步提高。就儀器而言,國產檢測儀器的性能有待進一步提高。仍需通過開展實驗室全麵質量管理,逐步達到檢測結果的互認,為臨床提供可靠的診療依據。

Objective To analyze the external quality assessment(EQA)results for kidney function indices of Shanghai clinical laboratories in 2012,to understand the status of creatinine(Cr),uric acid(UA)and urea(UN) determinations,and to provide the experimental data for standardization. Methods A total of 1 0 different concentrations of control materials were distributed to Shanghai laboratories for the routine chemical EQA.Data was classified into different groups,according to the instruments.The means(x),standard deviation(s)and coefficient of variation (CV)were calculated for each group after eliminating outliers.Results In EQA results,the CV among laboratories of Cr,UA and UN were 1 .30%-1 2.73%,1 .06%-6.78% and 1 .55%-8.79%,respectively for different groups.The lowest variation of Cr was in Import 1 group.The range of CV was 1 .70%-5 .1 5% in detecting (46-574)μmol/L of Cr.The lowest variation of UA was in Import 3 group.The range of CV was 1 .49%-2.1 9% in detecting (1 32-550)μmol/L of UA.The lowest variation of UN was in Import 2 group.The range of CV was 1 .55%-2.74% in detecting (3.15-18.13)mmol/L of UN.Conclusions The determination performance of Cr needs to be further improved in Shanghai laboratories.The determination performance of homemade instruments remains to be further improved in terms of equipment.It is needed to strengthen the laboratory quality management to gradually achieve the mutual recognition of test results and to provide the reliable diagnosis and treatment references.
