临床尿检中尿沉渣镜检与尿液分析仪2种方法对比分析

摘要

Objective Comparison and analysis of advantages and disadvantages for the methods of microscopic examination of the urine analyzer and urine sediment urine test. Methods To collect 300 urine specimens for testing, testing method for microscopic examination of the urine analyzer and urine sediment, the main evaluation indexes: the white blood cells (WBC), red blood cells(RBC), protein (PRO). Result After testing, the use of the testing results of the urine analyzer is positive in 237 patients, after urinary sediment microscopy detection, normal 36 cases, false positive rate 15.2%. The testing results of the urine analyzer, negative for 63 cases, microscopy, anomalies, 8 cases of false negative rate was 12.7%. Microscopy examination, found that 10 patients of white blood cells to normal, the false positive rate is 19.2%. PRO and WBC two indicators all 17 cases of patients, the WBC and RBC in 25 patients with two indicators of abnormal RBC and PRO two abnormalities in 18 cases, PPO, WBC, RBC 13 patients with three indicators are abnormal. Conclusion Urine analyzer is adopted to improve the detection, detected by the negative rate is higher, therefore, in clinic according to the demand of the actual situation to select for microscopic examination.%目的：比较和分析尿液分析仪和尿沉渣镜检尿检方法的优劣。方法对我院收集的300份尿液标本进行检测，检测的方法为尿液分析仪和尿沉渣镜检，主要的评价指标：尿液中的白细胞（WBC）、红细胞（RBC）、蛋白质（PRO）。结果经过检测之后，采用尿液分析仪检测的结果中有237例为阳性，经过尿沉渣镜检检测，其中正常的有36例，假阳性率15.2%。采用尿液分析仪检测的结果中，阴性为63例，进行镜检，有8例出现异常，假阴性率12.7%。镜检检测，发现有10例患者的白细胞正常，假阳性率为19.2%。PRO和WBC两项指标都正常的患者有17例，WBC与RBC两项指标异常的患者有25例，RBC与PRO两项指标异常的有18例，PPO、WBC、RBC三项指标均异常的患者有13例。结论采用尿液分析仪进行检测，其所检测出的阴性率比较高，所以，在临床上要根据实际情况的需求来选择进行镜检。
