国际旅行卫生保健中心某医学实验室质量控制分析

Quality control analysis for a medical laboratory of International Travel Healthcare Center

目的分析实验室内部质量控制(内部质控)数据,查找不足,为更好地开展内部质控提供参考依据。方法收集实验室2012年度5个检测项目990个点的内部质控数据,进行统计分析。结果失控、警告、位移和漂移分别占质量控制(质控)总点数的0.20%、0.20%、1.82%和0.61%;人类免疫缺陷病毒抗体(anti-HIV)、丙型肝炎病毒抗体(anti-HCV)、梅毒螺旋体抗体(anti-TP)、乙型肝炎病毒表面抗原(HBsAg)和丙氨酸氨基转移酶(ALT)质控异常分别占各自质控总点数的3.05%、0、0.51%、0.51%和10.10%;试剂、质控品、人为因素、仪器设备和其他原因产生的质控异常分别占质控总点数的0.20%、1.41%、0.30%、0.30%和0.61%。结论位移是最多见的质控异常形式,ALT是发生质控异常最多的检测项目,质控品是质控异常最常见的原因,这些是实验室内部质控的重点。

Objective To analyze the data of a Lab internal quality control（IQC） to find the problem, and to provide the scientific basis. Methods The data of Lab IQC for 5 test items 990 pints were collected and analyzed during 2012. Results Out of control, warning, displacement and drift accounting for the total quality control（QC） points were 0.20%, 0.20%, 1.82% and 0.61%. Anti-HIV,anti-HCV,anti-TP,HBsAg and ALT accounting for its test item QC total points were 3.05%, 0, 0.51%,0.51% and 10.10%. The reagent,standard material,human,instrument and other reasons accounting for the total QC points were 0.20%,1.41%,0.30%,0.30% and 0.61%. Conclusion Displacement is the most common for abnormal QC, ALT is the most abnormal QC occurrence test item and standard material is the most reason for abnormal QC. It is necessary to pay more attention to the factors of IQC in future.
