【摘要】 目的调查长沙地区健康儿童尿液UF-500i全自动尿液分析仪检测的正常参考范围。方法应用sysmex-UF-500i全自动尿液分析仪检测2011年2～8月来院体检的健康儿童共1022例(男732例,女290例,年龄1d～18y)的尿液红细胞(RBC)、白细胞(WBC)、上皮细胞(EC)、管型(CAST)、细菌数(BACT)等。按年龄分为<28d,28d～6m,6m～1y,>1y4组。结果 RBC、WBC、EC、BACT性别间差异有统计学意义;<28d组男性RBC、WBC高于其他3组(P<0.001)、28d～6m组CAST低于>1y组(P=0.002);<28d组女性EC高于其他3组(P<0.001)、6m～1y组RBC低于其他3组(P<0.001)、28d～6m组BACT高于6m～1y组及>1y组。结论年龄、性别不同,儿童尿液RBC、WBC、EC、BACT、CAST参考范围存在差别,在临床结果解释时应考虑以上因素;各实验室应根据自身条件建立相应的健康人群参考范围。更多还原

【Abstract】 Objective To investigate the normal reference range of urinary formed elements in children of Changsha.Methods During February 2011 to August 2011,sysmex UF 500i were used to count urinary red blood cells(RBC),white blood cells(WBC),epithelia cells(EC),casts of urine(CAST) and bacteria(BACT) in 1 022 children,accepting physical examination,including 732 boys and 290 girls,aged 1 d-18 y,who were divided into 4 groups according to age,including <28 d group,28 d-6 m group,6 m-1 y group and >1 y group.Results There were significant differences in RBC,WBC,EC and BACT between boys and girls(P<0.05).The RBC and WBC in group<28 d were higher than the other 3 groups,the CAST in group 28 d-6 m were lower than group >1 y for boys(P<0.05).The EC in group <28 d were higher than the other 3 groups(P<0.05).The RBC in group 6 m-1 y were lower than the other 3 groups(P<0.05).The BACT in group 28 d-6 m were higher than group 6 m-1 y and group>1 y for girls(P<0.05).Conclusion Children urinary formed elements might be different between different age and sex.These factors should be considered in the interpretation of the clinical results.The laboratory should establish its own local reference ranges.更多还原
