【摘要】 目的:比較朗邁LabuMat全自動尿干化學分析儀、朗邁UriSed全自動尿沉渣儀分析儀對尿液檢測的準確性、可靠性,為臨床提供快速、準確的結果。方法:隨機抽取1782例患者尿液標本,分別用朗邁LabuMat全自動尿干化學分析儀、朗邁UriSed全自動尿沉渣儀分析儀及人工鏡檢三種方法進行檢測,對檢測結果進行比較。結果:以顯微鏡檢查作為對照,朗邁Urised全自動尿沉渣分析儀檢查紅細胞靈敏度、特異度、Kappa值分別為:98.66%(960/973),97.78%(791/809)、0.98;朗邁LabuMat全自動尿干化學分析儀檢查紅細胞靈敏度、特異度、Kappa值分別為:99.59%(969/973)、95.92%(776/809)、0.97。朗邁Urised全自動尿沉渣分析儀檢查白細胞靈敏度、特異度、Kappa值分別為:98.59%(1190/1207),95.48%(549/575)、0.96;朗邁LabuMat全自動尿干化學分析儀檢查白細胞靈敏度、特異度、Kappa值分別為:77.38%(934/1207)、73.91%(425/575)、0.63。結論:朗邁(LabuMat+UriSed)全自動分析儀檢測速度快、結果比較準確,但不能完全取代人工鏡檢,必須與人工鏡檢合理的結合才能最快速、準確地為臨床提供檢驗結果。

【Abstract】 Objective:To compare the accuracy and dependability of LabuMat automatic urine dry chemical analyzer and UriSed automatic urine sediment analyzer for urine testing,and to provide the fastest and the most accurate results for clinic.Method:Urine samples of 1782 patients were randomly selected and detected by the three methods,detection results were compared.Result:Compared with microscopy,the sensitivity,specificity and Kappa values of RBC Urised automatic urine sediment analyzer were 98.66%(960/973),97.77%(791/809) and 0.98 respectively;the sensitivity,specificity and Kappa value of RBC LabuMat automatic urine dry chemical analyzer were 99.59%(969/973),95.92%(776/809) and 0.97 respectively.The sensitivity,specificity and Kappa values of WBC Urised automatic urine sediment analyzer were 98.59%(1190/1207),95.48%(549/575) and 0.96 respectively;the sensitivity,specificity and Kappa value of WBC LabuMat automatic urine dry chemical analyzer were 77.38%(934/1207),73.91%(425/575) and 0.63 respectively.Conclusion:LabuMat automatic urine dry chemical analyzer and UriSed automatic urine sediment analyzer can quickly and accurately provide clinical results,but they can not completely replace the manual microscopy,and they must be combined with manual microscopy to provide the fastest and the most accurate results for clinical.

尿液分析作為臨床檢驗的三大常規之一,標本采集方便、且能為泌尿系統及相關疾病診斷及治療提供重要依據,受到臨床醫生越來越多的重視,成為疾病診斷和常規體檢的必須手段。人工鏡檢的結果直觀、可靠,仍為尿液檢查的金標準[1]。但其操作復雜、費時、工作強度較大[2],不能完全適應臨床尿液檢測標本量的增加。隨著醫學技術的突飛猛進,全自動尿液檢測分析儀問世了。朗邁LabuMat全自動尿干化學分析儀檢測最快速度達到250樣本/h,朗邁UriSed全自動尿液有形成分分析儀最快達到100樣本/h,其檢測速度之快是人類手工鏡檢不可比擬的,在一定程度上彌補了人工鏡檢速度較慢的不足。……
