临床检验定量测定室内质量控制数据实验室间的比较

Interlaboratory comparison of Internal quality control data in clinical laboratory

目的研究实验室内质量控制数据实验室间比较。方法标准差指数(SDI)和变异系数指数(CVI)表示方法的准确度和精密度。SDI和CVI标识必须通过从室内质控数据实验室间比较计划提供者的数据进行评价。结果使用相同方法的实验室比对能帮助识别和调查问题。与所有实验室的比对能帮助识别方法和能力的问题。评价相同组历史和累积报告能反映出方法性能的变化。结论室内质控数据的实验室间比较计划收集和报告数据为实验室提供有价值的信息。

Objective We describe interlaboratory comparison of internal quality control data programs. Methods The SDI and CVI indicate method accuracy and precision.SDI and CVI flags must be evaluated by examining the numerical data from the peer group provider. Results Peer comparisons to laboratories using our method can help identify and investigate problems.Comparisons to all laboratories can reflect changes in method performance. Conclusion Interlaboratory comparison of internal quality control data programs collect and report data to provide valuable information.
