尿干化学分析法与Diasys R／S 2003尿沉渣工作站对尿中有形成分检测的对比

Comparison of Dry - Chemistry Method and Diasys R/S 003 Urinary Sediments Analysis Workstation in Detecting Visible Compo-nents in Urine Samples

目的探讨用Diasys R／S 2003尿沉渣工作站与干化学法检测红、白细胞及管型的应用价值。方法按NCCLS Litera- tion GP 16-A(ISBN 1-56238-282-9)的要求收集442份临床尿液标本,同时用DiasysR／S 2003尿沉渣工作站和干化学法进行红、白细胞及管型分析。结果以DiasysR／S 2003尿沉渣工作站为基础,评价干化学法,红细胞漏诊率为12．8％,误诊率为 20．7％;白细胞漏诊率为34．6％,误诊率为7．4％;管型漏诊率为45．0％。结论干化学法检测红、白细胞及管型有较高的漏诊率和误诊率,两种方法只能互为补充,而不能相互代替,尿于化学法分析之后有必要对标本进行显微镜检查。

[Objective]To explore the applicable value of dry - chemistry method and Diasys R/S 003 urinary sediments analysis workstation for detecting red and white blood cells and urine casts. [Methods]442 urine samples were collected under the requirement of NCCLS Literation GP16 - A （ ISBN1 - 56238 - 282 - 9） ; dry - chemistry method and Diasys R/S 003 urine sediments analysis workstation were applied to analyze the red and white blood cells and urine casts. [Results]Based on Diasys R/S 003 urine sediments analysis workstation, the evaluation of dry - chemistry method was as follows： the rate of lost diagnosis of red blood cells was 12.8%, misdiagnosis rate was 20.7% ; the rate of lost diagnosis of white blood cells was 34.6%, misdiagnosis rate was 7.4% ; the rate of lost diagnosis of urine casts was 45.0%. [ Conclusion] Dry- chemistry method has been proved to have high rate of lost diagnosis and misdiagnosis, which should be complemented by another method; microscopic examination is necessary after dry- chemistry analysis.
