摘要:

目的 探讨使用UF-1000i尿沉渣分析仪检测白细胞及小圆上皮细胞假性升高的主要原因。方法 随机收集门诊尿液标本,分别用UF-1000i尿沉渣分析仪和显微镜进行检测,对2种方法检测结果进行统计学分析,分析导致UF-1000i尿沉渣分析仪检测白细胞及小圆细胞假性升高的影响因素。结果 UF-1000i尿沉渣分析仪检测白细胞的假阳性率为12.58%,导致假阳性的因素主要包括小圆上皮细胞(69.6%)、细菌(12.8%)、扁平上皮细胞(8.0%)和脂肪滴(6.4%);检测小圆上皮细胞的假阳性率为4.6%,导致假阳性的因素主要包括白细胞(67.9%)、脂肪滴(15.5%)和滴虫(11.9%)。结论 当尿液病理成分增加时,多种因素可以影响UF-1000i尿沉渣分析仪对白细胞和小圆上皮细胞的检测结果,因此应用UF-1000i尿沉渣分析仪检测只能作为初步筛查方法,显微镜镜检仍然是尿沉渣检查的金标准。

Abstract:

Objective To investigate the main causes for false increasing of white blood cells and small round epithelial cells determined by UF-1000i urine sediment analyzer. Methods Urine samples of outpatients were collected. UF-1000i urine sediment analyzer and microscopy were used,and the results of these 2 methods were compared. The main causes for false increasing of white blood cells and small round epithelial cells were evaluated. Results The false positive rate of white blood cells determined by UF-1000i urine sediment analyzer was 12.58%,mainly due to small round epithelial cells(69.6%),bacteria(12.8%),flat epithelial cells(8.0%) and fat droplets(6.4%). The false positive rate of small round epithelial cells was 4.6%,mainly due to leukocytes(67.9%),fat droplets(15.5%) and trichomoniasis(11.9%). Conclusions When the urine pathological components increase,a variety of factors can affect UF-1000i urine sediment analyzer's determination results on white blood cells and small round epithelial cells,and false positivity appears. The application of UF-1000i urine sediment analyzer can only be a determination as a preliminary screening method,and microscopy is still be gold standard for urine sediment analysis.
