摘 要: | 目的通过检测系统性能验证,分析尿白蛋白室间质评成绩不满意的可能原因及是否影响临床样本检测。 方法回顾室内质控结果,检查仪器及试剂状态;复检剩余的EQA质控样本;对于透散比浊法、散射比浊法检测尿白蛋白进行分析测量范围验证(EP6-A);检测40份患者尿液样本,对于透射比浊法、散射比浊法检测准确度差异进行分析(EP9-A2);分析CAP尿液能力验证实验结果,与其他实验室进行临床样本比对。结果室内质控均在控,复测结果与上报结果一致,分析测量范围分析显示两个方法没有显著差异,两种方法检测患者新鲜尿标本差异在允许误差范围内;两次CAP质评回报满意(PT=100%),两种方法间无明显差异;与其他实验室两次比对偏奇在1/2PT范围内。 结论本实验室透散比浊法、散射比浊法检测尿白蛋白尿白差异小,准确度好,室间质评成绩不影响临床样本的检测质量。

Abstract: | Objective To analyse the reasons of ALBU EQA unacceptable. Methods The quality control data were reviewed, the EQC samples stored in -80 ℃ were reran with instruction status checked. Measuring range evaluation of ALBU of turbidimetry and scatteringmetry were performed. The accuracy of turbidimetry and scatteringmetry were ompareed through detected ALBU in 40 clinical samples. ALBU CAP proficiency testing results were analyzed. Results The IQC data were in control, rerun data were accordance with reported data, the ALBU measuring range of turbidimetry and scatteringmetry is uniformity, the accuracy of turbidimetry and scatteringmetry detecting ALBU in clinical samples were similar. The evaluation results of CAP proficiency testing were acceptable, the bias between turbidimetry and scatteringmetry detecting ALBU were limited. Conclusion ALBU EQC unacceptable will not affect the accuracy of clinical sample results . |
