摘要
目的分析不同医学决定水平下总蛋白(TP)的不确定度,为临床诊断治疗提供帮助。方法根据《分析化学中不确定度的评估指南》(CNAS-GL06),利用卫生部临床检验中心室间质评反馈信息,同时根据仪器的水平计算公式确定不确定度各分量,计算不同医学决定水平下TP的不确定度。结果 TP在低、正常、高3个医学决定水平的不确定度分别为3.30%、2.84%、2.89%;其扩展不确定度分别为6.60%、5.68%、5.78%,均在允许总误差(TEa)范围内。结论在不同医学决定水平时,TP的测量不确定度不同,对检测结果的分析需考虑不确定度。
Objective To analyze different medical decision levels of total protein（TP）of uncertainty.Methods Based on Guide to Uncertainty Evaluation in Chemistry Analysis（CNAS-GL06：2012）feedback information and of the National Center for Clinic Laboratories（NCCL）the component of the uncertainty was determined according to the calculation formula of concentration on the instrument at the same time,and to calculate the uncertainty of TP in different medical decision levels.Results The uncertainties of TP in the low,normal and high medical decision level were 3.30%,2.84%,2.89%;the expanded uncertainties were 6.60%,5.68% and 5.78%,respectively,all of which were in the allowable total error（TEa）range.Conclusion It will provide certain guiding significance in the clinical diagnosis and treatment processes to calculate the uncertainty of TP in different medical decision levels.
