COBIO全自动尿液分析工作站性能评价

目的对COBIO(科宝)全自动尿液分析工作站(由combi XL试纸条分析仪和COBIOxs尿有形成分分析仪2部分联机而成)的性能及使用效果进行评价。方法采用COBIO全自动尿液分析工作站,对仪器的重复性、线性、准确性、灵敏度等性能进行验证试验。结果高、中、低值标本批内精密度(CV%)白细胞为4.5、6.0、10.0,红细胞为2.4、5.0、13.8,上皮细胞为4.8、7.0、13.5;红细胞在5～1 210个/μL线性范围间相关系数为0.999,白细胞在4～498个/μL线性范围间相关系数为0.998;自动识别准确率:红细胞99%、白细胞98%、上皮细胞93%、管型58%、草酸钙结晶93%、尿酸结晶95%、酵母菌90%。结论 COBIO全自动尿液分析工作站具有真正全自动操作、检测速度快、结果可靠、成本低等优点,具有很高的临床应用价值。

The performance evaluation of COBIO automatic urine system

Objective To evaluate the performance of COBIO automatic urine system （combi XL analyzer and COBIO xs automatic urine sediment analyzer）. Methods The repeatability, lineafity, accuracy and sensitivity were determined by COBIO automatic urine system. Results The within-run coefficients of variation （ CV% ） of white blood cell in high, middle and low-value samples were 4.5, 6.0 and 10 respectively. They were 2.4, 5.0 and 13.8 for red blood cell,and 4.8,7.0 and 13.5 for epithelial cell. The correlation coefficient of red blood cell was 0. 999 with 5-1210/~L. The correlation coefficient of white blood cell was 0.998 with 4-498/p.L. The accuracies of red blood cell, white blood cell, epithelial cell, cast cell,calcium oxalate,uric acid crystallization and Candida were 99% ,98% ,93% , 58%, 93%, 95% and 90%, recpectively. Conclusions COBIO automatic urine system has the advantages of automation, high testing speed, accuracy and low cost, and it has a good significance in clinical application.
