差值校验在临床实验室中的应用

Application of delta checks in clinical laboratories

差值校验是一种基于患者数据的质量控制方案,用于识别分析各阶段误差或患者病情显著变化。与传统室内质控方案相比,差值校验拥有实时监控、无额外检测成本等特点,已得到越来越多的应用。在检验报告自动审核系统中,差值校验作为一类重要的审核规则用于拦截变化异常的检验报告并提交人工审核。该文阐述差值校验的发展历史、参数选择、在质量控制和检验报告自动审核中的应用价值。

The delta checks are one of the patient-based quality control options to identify the errors and the significant changes in patients′condition.Compared with the traditional internal quality control method,the delta checks have the characteristics of real-time monitoring,with no additional detecting cost,thus the delta checks are widely used in clinical laboratories.In addition,the delta checks are also useful in the auto-verification system to screen out the abnormal results for manual verification.This article reviewed the delta checks′development history,parameters selection,application values in quality control and auto-verification.
