天津地区UF-50尿沉渣分析仪参考值的调查

The investigation on the reference ranges of multiple indices with UF-50 urine sediment analyzer in Tianjin Region

目的调查天津地区UF-50尿沉渣分析仪的正常参考值。方法用尿常规分析仪和尿液离心镜检两种方法筛选出正常尿液标本704份，用UF-50尿沉渣分析仪测定白细胞、红细胞、上皮细胞、管型、细菌的值，用百分位数法确定参考值。结果在95％可信区间的UF-50尿沉渣分析仪的参考范围为：红细胞0～14．8个／微升，白细胞0～17．3个／微升，上皮细胞0～14．7个／微升，管型0～0．44个／微升，细菌0～2642．3个／微升。结论确定的参考范围基本可信，应用UF-50进行尿沉渣检查结果可靠，可广泛应用于临床泌尿系统疾病的辅助诊断。

Objective To investigate the reference ranges of multiple indices with UF-50 urine sediment analyzer in Tianjin Region. Methods Urinary routine analyzer assay and urinary sediment microscopic analysis were performed to screen 704 normal urine samples. UF-50 urinary sediment analyzer was adopted to determine reference ranges of multiple indices [red blood cells （RBC）, white blood cells （WBC） , epithelial cells （EC）, casts and bacteria] with percentile method. Results The multiple indices reference ranges of 95% confidence interval with UF-50 urine sediment analyzer were as follows ： RBC 0-14.8,WBC 0-17.3,EC 0-14. 7,casts 0-0.44,and bacteria 0-2 642.3. Conclusion The established reference ranges are credible. UF-50 urine sediment analyzer can acquire experimental results reasonable, and can be widely used in the clinical diagnosis of disorders of urinary system.
