摘　　要：目的　评估重庆天海 US 2020 全自动尿沉渣分析仪的性能及临床应用。方法　用pH6.5的新鲜尿液配制红细胞与5个量级单位作正确分析,用双盲法对同一标本中有形成分重复冲池数10次,求出其CV%。并随机选择120份尿液标本,分别用重庆天海US 2020全自动尿沉渣分析仪法、牛鲍氏板计数对红细胞、白细胞、上皮细胞、管型作可比性比较。结果　红细胞与5个数量级的理论值与实测值的误差<-3.9%,白细胞CV值为4.1%,红细胞CV值为4.4%,上皮细胞 CV值为6.6%,管型CV值为 7. 7%,与牛鲍氏板法相比 P> 0. 05,无显著性差异。红细胞携带污染率为0.21%,白细胞携带污染率为0.45%,上皮细胞及管型携带污染率为 0。稀释试验显示良好线性范围。结论　重庆天海US 2020全自动尿沉渣分析仪主要指标符合要求,自动化程度高,尿沉渣检查标准、规范。其快速准确,操作简便,是目前较理想的全自动尿沉渣分析仪。Object To evaluate characters and application in clinic for US-2020 urinary sediment automatic analyzer.Methods To make up five measure unit suspension of red blood cell using fresh urine(pH=6.5)for proper analysis.The shape components of the same sample recounted for tens times to get its average standard and confficient of variation with double-blind method.To compare the comparability of red blood cell,white blood cell and cast on with 120 urinary samples random selection.Results In five measure unit of red blood cell, the error of the theoretical value and the actual measurement <-3.9%,CV value:4.1% for WBC,4.4% for RBC,6.6% for EC and 7.7 for cast.The results showed no significant difference compared with Neubauer′s method(P>0.05).The corretation displayed significant mean in red blood cell ,white blood cell and cast of dench and the neubauer (P> 0.05 ). The contamination rate was 0.21% in RBC. But that of WBC was 0.45%, espithelial cell as well as cast was zero.Dilution test displayed better linear range.Conclusion US-2020 has characters of accuracy,easy operation, more quick,safety,reliability and saving cost etc.It is a better urinary sediment analysis equipment.
