摘要:

检验全过程的每个步骤都存在着固有的风险。基于个体试验结果的Delta检查是一种能减少这些风险的方法,可以作为传统实验室质量控制方法的补充,能检出质控品无法检出的问题。Delta检查可用于检验全过程的不同阶段,包括检出识别错误和处理不当的标本、患者情况的真实改变、仪器或实验室人员的差错等问题;也可用于即时检验(POCT)的评估。文章介绍了如何在检验前、中、后阶段以及POCT中实施Delta检查,包括候选分析项目的选择、监测参数的制定、检查界限的设置以及Delta检查的有效性评估,以期给临床实验室提供一定的参考。

Abstract:

Risks are inherent in each step of whole testing process. Delta checks based on individual patients' data are methods for mitigating these risks. Delta checks can be used as a complementary tool for traditional laboratory quality control to determine issues that quality control materials may not address. It can be applied into different phases in whole testing process,including determining misidentified and mishandled specimens,true patients' changes,instrumentation and personal errors,as well as the evaluation of point-of-care testing(POCT). The review introduces the application of delta checks in POCT and pre-examination,intra-examination and post-examination phases,including selecting candidate analytes,establishing monitor parameters,setting limits and the evaluation of usefulness,hoping to provide a reference for clinical laboratories.

Key words: Quality control, Quality assurance, Delta checks, Laboratory errors
