摘要
目的:及时发现测定误差成因,确保血药浓度监测质量。方法:分析环孢素和苯妥因内部质量控制原始数据的分布和变化趋势,根据统计学原理判断测定误差的性质和来源。结果:被调查项目测定结果大于或小于靶值的数据分布明显失衡,具有极显著性或显著性差异(P<0.01或P<0.05)。结论:某些实验室测定准确性较差,除与随机误差有关外,还与系统误差有关。
OBJECTIVE： To discover early the latency factors influencing assay accuracy and to improve the quality of therapeutic drug monitoring （TDM）. METHODS： The distribution and changing trend in the original data of internal quality control （IQC） for cyclosporine and phenytoin were analyzed, and the property and source of determination errors were estimated according to the statistical theory. RESULTS： The determined data which were more or less than target values were evidently out of balance in distribution, which showed greatly significant or significant difference（P 〈 0.01 or P 〈 0.05）.CONCLUSION ： Low accuracy in laboratory assay is not only related to random errors but also to system errors.
