全自动尿沉渣分析仪检测管型的影响因素分析

目的 探讨全自动尿沉渣分析仪检测管型的影响因素.方法 用UF1000、科宝XS、人工显微镜检查(人工镜检)三种方法对137例肾病患者尿液进行管型测定分析比较.结果 以人工镜检为标准,UF1000测定管型的假阳性率为35.1%,科宝XS的假阳性率为22.3%,UF1000与科宝XS的测定结果与人工镜检法比较差异均具有统计学意义(P<0.05),黏液丝、上皮细胞等因素可干扰全自动尿沉渣分析仪对管型的测定结果.结论 全自动尿沉渣分析仪只能作为测定管型的筛查试验,遇管型阳性结果时,必须用人工显微镜检测复核.

Analysis on influencing factors of full-automatic urine sediment analyzer for detecting cast

Objective To investigate the influencing factors of the full-automatic urine sediment analyzer for detecting cast.Methods The three methods UF1000,COBIO XS and manual microscopic examination were adopted to analyze and compare the urine cast detection in 137 cases of kidney disease.Results With the manual microscopy as standard,the false-positive rate of detecting cast was 35.1% for UF1000 and 22.3% for COBIO XS,showing statistical difference between them and the manual microscopy（P0.05）.The factors such as mucous wire and epithelial cells could interfere with cast detection results.Conclusion The full-automatic urine sediment analyzer can be only used for the screening test of cast.In the positive results of cast,the manual microscopy must be used for rechecking.
