摘　　要：目的探讨实验室内不同全自动尿沉渣分析仪结果质量保证的方法。方法将两台仪器分别进行保养,包括空白、精密度、携带污染率测试,用配套质控品每天监控,定期进行比对试验。比对项目为RBC、WBC、上皮细胞(EC)和电导率(CON)。结果两仪器检测显示,RBC、WBC结果比较差异无统计学意义(P>0.05),EC、CON结果比较差异有统计学意义(P<0.05)。偏差分析显示,两台仪器RBC、WBC、EC、CON结果一致性较好。结论室内质量控制可保证检测结果的稳定性;定期对检测项目相同的不同仪器进行比对,对保证检测结果的一致性是非常必要的。Objective To investigate quality assurance of different automatic urine sediment analyzers in the same laboratory. Methods After ordinary maintenance was completed, blank test,precision and carry over rate detection were performed on two analyzers. Quality control was detected everyday to monitor the analyzers and comparative tests were performed periodically on red blood cells （RBC） ,white blood celIs（WBC） ,epithelial cells（EC） and conductivity（CON）. Results There was no statistical significance of RBC and WBC between two analyzers（P〉0.05）, but statistical significance of EC and CON was observed（P〈0.05）. Deviation analysis showed there was fine consistency of RBC,WBC,EC and CON between two analyzers. Conclusion The constancy of detected results could be ensured by internal quality control. It might be necessary to perform comparative tests between analyzers periodically to confirm the consistency of detected results.
