本文对ULTRA M全血急诊分析仪检测LAC、BUN、GLU三项生化指标的准确性 ,做了系统评价。测定结束表明Lac、BUN、Glu日内及日间变异系数 (CCV)均低于卫生部临检中心推荐的CCV(Lac11 6 %、BUN6 %、Glu5 % )。平均回收率分别为 96 2 5 %、91 5 0 %、10 5 77% ;Lac在 0 4～ 0 8mol/L、BUN在 3～ 18mg/dl、Glu在 6 5～ 10 0mgl/dl范围内线性关系良好 (r=0 9998、0 9980、0 9979)。说明该分析仪器具有电极膜性能稳定、重复性好、精密度高等优点 ,可为临床诊断提供科学的依据
In this paper, ULTRA M whole blood emergency analyzer for the detection of LAC, BUN, GLU three biochemical indicators of accuracy, made a systematic review. The end of the experiment indicated that the intra-day and intra-day coefficient of variation (CV) of Lac, BUN and Glu were all lower than the CCV (Lac11 6%, BUN6%, Glu5%) recommended by the Ministry of Health Clinical Laboratory. The average recoveries were 96 2 5%, 91 5 0% and 10 5 77%, respectively. Lac concentrations ranged from 0 to 48 mol / L, BUN ranged from 3 to 18 mg / dL, Glu ranged from 65 to 100 mgl / dl Good relationship (r = 0 9998,0 9980,0 9979). Indicating that the analytical instrument has the advantages of stable electrode membrane performance, good repeatability, high precision, etc., which can provide a scientific basis for clinical diagnosis
