摘要
目的:评价UF-1000i型尿沉渣分析仪的主要性能指标。方法:采用新鲜尿液和定值质控品对UF-1000i型主要分析指标精密度、携带污染率、线性范围、不确定度进行分析。结果:UF-1000i型检测白细胞(WBC)、红细胞(RBC)、细菌(BACT)、上皮细胞(EC)、管型(CAST)的批内精密度分别为4.0%~7.6%、4.4%~6.6%、5.9%~8.9%、5.7%~10.7%、7.0%~13.5%。UF-1000i型检测WBC、RBC、BACT、EC、CAST的日间精密度分别为2.1%~6.3%、4.8%~5.3%、7.2%~9.7%、8.0%~15.0%、9.5%~14.1%。检测新鲜尿液标本WBC、RBC、BACT、EC、CAST的携带污染率分别为0.120%、0.039%、0.084%、0.700%、1.640%。尿液WBC、RBC、BACT、EC、CAST分别在1.4~5 097/μl、1.2~4 885/μl、8~16 540/μl、2.9~204/μl、1.2~19.4/μl浓度范围内,具有良好的线性。UF-1000i型测定WBC、RBC、EC、CAST、BACT的相对偏差分别为2.4%~9.0%、0.9%~9.8%、-18.2%^-18.0%、-13.5%~5.1%、-3.7%~6.8%。结论:UF-1000i型的主要性能指标合格,可用于尿液有形成分分析。
Objective：To evaluate the main performance index of UF-1000i urinary sediment analyzer. Methods：The precision, contaminative rate,linear range and uncertainty of the UF-1000i were analyzed by detecting fresh urine and constant quality control product. Results：The within-run precisions（CV） of UF-1000i in detecting WBC,RBC,BACT,EC,CAST were 4. 0% -7. 6%,4. 4%-6. 6%,5. 9% -8. 9%,5. 7% -10. 7% and 7. 0% -13. 5%,respectively. The inter-day precisions of UF-1000i in detecting WBC, RBC,BACT,EC,CAST were 2. 1% -6. 3%,4. 8% -5. 3%,7. 2% -9. 7%,8. 0% -15. 0%,9. 5% -14. 1%,respectively. The contaminative rates of UF-1000i in detecting WBC,RBC,BACT,EC,CAST in fresh urinary were 0. 120%,0. 039%,0. 084%,0. 700%and 1. 640%,respectively. The levels of WBC,RBC,BACT,EC and CAST in urinary were 1. 4 -5 097/μl,1. 2 -4 885/μl,8 -16 540/μl,2. 9-204/μl and 1. 2 -19. 4/μl, respectively, which was good linear correlation. The relative deviations of UF-1000i in detecting WBC,RBC,BACT,EC and CAST were 2. 4% -9. 0%,0. 9% -9. 8%,-18. 2% - -18. 0%,-13. 5% - -5. 1% and-3. 7% - -6. 8%,respectively. Conclusions：The main performance index of UF-1000i is qualified,which can be used to analyze the formed elements of urinary.
