【摘要】 目的探讨UF-1000i尿液有形成分分析仪与干化学方法、手工显微镜检查尿中红细胞(RBC)、白细胞(WBC)的符合情况及影响因素。方法使用UF-1000i尿有形成分分析仪、干化学分析仪与显微镜分别检测996例尿液标本中RBC、WBC,将3种方法的检测结果进行比较。结果分别以RBC、WBC超过25和30个/μL为阳性界值,3种方法检测RBC的完全符合率为78.4%,WBC完全符合率为67.2%;以仪器设定等级划分为标准,则3种方法检测RBC、WBC符合率分别为85.6%和86.5%;UF-1000i测RBC假阳性率为4.62%;测WBC假阳性率为1.81%。结论 UF-1000i尿有形成分分析仪与显微镜检查及干化学方法符合率良好,较UF-100对RBC识别能力提高,抗干扰能力增强。更多还原

【Abstract】 Objective To compare the performances of UF-1000i urine sediment analyzer,dry chemistry method and manual microscopy in the determinations of red blood cell(RBC) and white blood cell(WBC).Methods 996 urine samples were collected.The RBC and WBC were determined by UF-1000i urine sediment analyzer,dry chemistry method and manual microscopy.The results were compared and analyzed statistically.Results With the positive cut-off value of 25 per μL for RBC and 30 per μL for WBC,the complete concordances were 78.4% for RBC and 67.2% for WBC.The concordances defined by the grade between the 2 analyzers were found to be 85.6% for RBC and 86.5% for WBC.The false positive rates of the UF-1000i were 4.62% for RBC and 1.81% for WBC.Conclusions These 3 urinalysis methods show good concordance with each other in urine sediment examination.The UF-1000i is more accuracy and anti-interferential than UF-100,but manual microscopy is still necessary.更多还原
