摘要
目的通过LabUMat尿液干化学分析仪(简称干化学)和Urised有形成分分析仪的检测结果与显微镜镜检结果的符合率,探讨尿液镜检的复检规则。方法收集1 040例门诊及住院儿童患者的尿液标本,先用朗迈全自动尿液分析仪进行尿液干化学和尿液有形成分的检测,然后进行显微镜检测,探讨自动化尿液分析仪尿常规分析的复检规则;通过漏检率对规则进行评价,且能避免肾功能异常的患者漏诊的复检规则。用200例标本对该复检规则进行临床验证。结果用于研究复检规则的标本中,镜检结果阳性标本占58.65%,阴性标本占41.35%。在阳性检测标本中,以RBC阳性居多,RBC阳性标本占50%,WBC阳性标本占23.08%,CAST阳性标本占7.69%。设置规则的符合率87.5%,漏检率分别是2.9%。用200例尿液标本对复检规则进行验证,符合率89.52%,漏检率2.4%。结论干化学潜血(BLD),白细胞(LEU),蛋白(PRO)和Urised有形成分分析仪RBC,WBC,管型(CAST)的检测结果不相符,或相差2个级差均要进行复检。
Objective To investigate the recheck rule by investigating the coincidence rate of the results detected by the LabU‐Mat urine dry chemistry analyzer and the Urised tangible composition analyzer with the results detected by the microscope examina‐tion .Methods 1 040 urine specimens from children outpatients and children inpatients were collected .Firstly ,the specimens were analyzed by the LabUMat urine dry chemistry analyzer and the Urised tangible composition analyzer ,and then detected by using the microscopic examination for investigating the recheck rule of the routine analysis by the urine automatic analyzer ;the regulation was evaluated by the missed detection rate ,and then the recheck rule avoiding the missed diagnosis of abnormal renal function was also evaluated .Finally ,clinically verify the rules adopting 200 specimens to perform the clinical verification on this recheck rule .Results Among the specimens used for researching the recheck rule ,the specimens of positive microscope examination results accounted for 58 .65% ,the specimens of negative results accounted for 41 .35% .In the positive detection specimens ,the specimens of RBC positive were the majority ,accounting for 50% ,the specimens of WBC positive accounted for 23 .08% and the specimens of CAST positive accounted for 7 .69% .The coincidence rate of the set rule was 87 .5% and the missed detection rate was 2 .9% .In conduc‐ting the verification on the recheck rule by 200 urine specimens ,the coincidence rate was 89 .52% and the missed detection rate was 2 .4% .Conclusion When the detection results of occult blood（BLD） ,WBC（LEU） and protein（PRO） by the dry chemistry analyzer and the detection results of RBC ,WBC ,CAST by the tangible composition analyzer are inconsistent or the differences among them are beyond 2 grades of differential ,the recheck by the microscopic examination should be performed .
