摘要
目的比较Sysmex UF-1000i和朗迈UriSed尿沉渣分析仪检测尿液有形成分结果的一致性,并与标准人工镜检进行比较,评价两种仪器检测尿液有形成分的性能差异。方法随机选取山西医科大学第六医院住院患者的尿液标本192例,分别用朗迈UriSed和Sysmex UF-1000i尿液分析仪进行检测,同时用显微镜对192例标本进行观察计数红细胞、白细胞、管型,以人工镜检结果为标准,对两种仪器检测结果进行比较。结果Sysmex UF-1000i、朗迈UriSed两种尿沉渣分析仪检测尿液中红细胞与人工镜检符合率为88.54%、85.42%,灵敏度为82.50%、85.00%,特异度为90.13%、85.53%;白细胞与人工镜检符合率为86.46%、90.10%,灵敏度为85.87%、96.74%,特异度为96.74%、87.23%;管型与人工镜检符合率为86.46%、83.85%,灵敏度为64.29%、78.57%,特异度为90.24%、84.76%。Sysmex UF-1000i和朗迈UriSed尿沉渣分析仪检测红细胞、白细胞、上皮细胞、管型、细菌、结晶的相关系数分别为0.961、0.905、0.923、0.466、0.517、0.680(P<0.001)。结论Sysmex UF-1000i与朗迈UriSed全自动尿沉渣分析仪检测有形成分准确性较高,Sysmex UF-1000i特异度较高,朗迈UriSed灵敏度较高,两种仪器有很好的检测相关性,均可用于临床,配合使用效果更好。
Objective To compare the uniformity of Sysmex UF-1000i urine analyzer and UriSed urine analyzer in detecting the visible components of urine,and to compare the results with the standard microscopic examination,and to provide the reference for clinical practice.Methods The urine samples of 192 patients in our hospital were randomly selected.UriSed and Sysmex UF-1000i were used to test the urine.At the same time,the red blood cells(RBC),white blood cells(WBC),and casts were counted by microscopic examination as gold standards,the results were compared and analyzed.Results Compared with microscopic examination,the coincidence rate of Sysmex UF-1000i for detecting of RBC,WBC and casts were 88.54%,86.46%and 86.46%.The sensitivity of Sysmex UF-1000i for detecting of RBC,WBC and casts were 82.50%,85.87%and 64.29%.The specificity of Sysmex UF-1000i for detecting of RBC,W BC and casts were 90.13%,96.74%and 90.24%.Compared with microscopic examination,the coincidence rate of UriSed for RBC,WBC and casts were 85.42%,90.10% and 83.85%.The sensitivity of UriSed for RBC,WBC and casts were 85.00%,96.74% and 78.57%.The specificity of UriSed for RBC,W BC and casts were 85.53%,87.23% and 84.76%.The correlation coefficients of RBC,WBC,epithelial cells,casts,bacteria,and crystals measured by Sysmex UF-1000i and UriSed urinary sediment analyzer were 0.961,0.905,0.923,0.466,0.517,and 0.680(P<0.001).Conclusion Sysmex UF-1000i and UriSed have higher accuracy in detecting urinary sediment,Sysmex UF-1000i is more specific,and UriSed is more sensitive.The two instruments have a good detection correlation and can be used in clinic.
