Laboratory quality control has been developed for several decades to ensure patients' safety, from a statistical quality control focus on the analytical phase to total laboratory processes. The sigma concept provides a convenient way to quantify the number of errors in extra-analytical and analytical phases through the defect per million and sigma metric equation. Participation in a sigma verification program can be a convenient way to monitor analytical performance continuous quality improvement. Improvement of sigma-scale performance has been shown from our data. New tools and techniques for integration are needed.
实验室质量控制已经发展了几十年，以确保患者安全，从侧重于分析阶段的统计质量控制到整个实验室流程。西格玛概念提供了一种便捷的方法，通过百万分之一缺陷率和西格玛度量方程来量化分析前和分析阶段的错误数量。参与西格玛验证计划是监测分析性能持续质量改进的便捷方式。我们的数据表明西格玛水平性能有所提高。需要新的整合工具和技术。
