尿沉渣法、干化学法及传统镜检测定尿液中有形成分的对比研究

Study on Comparison of Urine Sediment Method,Dry Chemical Method and Traditional Microscopy Determination of Urinary Visible Components

以传统镜检法结果作为标准,分别采用AX4280全自动尿液干化学法分析仪(干化学法)和IQ200尿沉渣分析仪(尿沉渣法)及两种方法的并联和串联检测新疆石河子地区532例患者的清洁中段尿,并评价两种方法的检测效果。结果显示,与传统镜检法比较,干化学法和尿沉渣法串联对尿液中红、白细胞检出率的阳性预测值高,具有临床意义;尿沉渣法对红、白细胞检测误诊率较高,需用镜检进行确认。尿沉渣法和干化学法可对临床提供一定的依据,但不能完全代替传统镜检,几种方法可作为互补,提高检测准确性。

Clean midstream urine of 532 cases in Shihezi city of Xinjiang province was detected by AX4280 full-automatic urine dry chemical equipment （dry chemical method） ,IQ200 urine sediment quantitative analyzer （urine sediment method） and the two methods paralleled and connected ,respectively .The efficacy of the two methods of testing was evaluated on the base of traditional microscopy ,which was used as a standard .The results showed that ,compared with microscope examination ,urine sediment method and dry chemical method cascaded were of positive predictive value ,which was significant to the practical clinic .While the misdiagnosis rate was higher in urine sediment method which needs to be further confirmed by microscopic examination .Urine sediment method and dry chemistry method can provide a basic result for clinical detection ,but cannot completely replace the traditional microscopy ,several methods can be used together to improve detection accuracy .
