肉眼血尿对尿常规分析的影响及处理措施探讨

Discussion on the effects of gross hematuria on routine urine analysis and treatment measures

目的探讨肉眼血尿对尿常规分析结果的影响。方法模拟血尿标本,观察其在离心处理前后对尿常规分析的影响。结果尿液标本中红细胞浓度达到100×10^9/L时,部分项目结果出现假阳性。离心处理后,白细胞酯酶及酮体的影响基本可以消除,但无法消除对蛋白质假阳性结果的影响。结论肉眼血尿对尿分析存在一定的干扰,离心后可消除部分干扰,尿液有形成分应以显微镜检查结果为准。

Objective To explore the effects of gross hematuria on the results of routine urine analysis. Methods Modeling hematuria was performed to observe its effects on routine urine analysis before and after centrifugation. Results Some parmeters appeared false positive results when the red blood cell concentration reached 100×10^9/L. The effects of leukocyte esterase and ketone body on the results of routine urine analysis could be almost eliminated after centrifuging the urine, but the effects on protein false positive results could not be eliminated. Conclusion Gross hematuria can impact some parmeters of routine urine analysis, and some interferences can be eliminated after centrifuging the urine. The visible components of the urine should be subject to the results of microscopic examination.
