152例健康儿童静脉血网织红细胞6项参数参考范围调查

目的:确定网织红细胞6项参数的参考范围。方法:利用RAM-1全自动网织红细胞分析仪检测152名健康儿童的网织红细胞百分比(RET%)、网织红细胞绝对值(RET#)、低荧光强度网织红细胞(LFR%)、中荧光强度网织红细胞(MFR%)、高光强度网织红细胞(HFR%)、网织红细胞成熟指数(RMI)。结果:男性RET#为(45.64±14.92)×109/L,女性RET#为(44.94±15.87)×109/L,男性RET%为(1.21±0.52);女性RET%(1.18±0.48),RMI为(11.3±5.075);LFR%为(89.99±3.98);MFR%为(9.05±3.46);HFR%为(1.15±0.78)。结论:网织红细胞6项参数参考范围因性别、仪器等因素的影响而有差异,各实验室应根据具体情况建立自己的参考范围。儿童RET#男、女无显著性差异。网织红细胞分群与性别无关。

Detection of reference limit for six parameters of reticulocyte count in 152 healthy children

Objective To establish a reference limit for six parameters of the reticulocyte count using RAM-1 automatic blood analyzer.Method The reticulocyte percent(RET%),the reticulocyte absolute counts(RET#),the low fluorescent reticulocyte(LFR%),the middle fluorescent reticulocyte(MFR%),the high fluorescent reticulocyte(HFR%) and the reticulocyte mature index(RMI) in 152 healthy children were counted by RAM-1 automatic blood analyzer.Results RET# in male was(45.64±14.92)×109/L,and in female was(44.94±15.87)×109/L.RET% in male was(1.21±0.52),and in female was(1.18±0.48).RMI was(11.30±5.075),LFR% was(89.99±3.98),MFR% was(9.05±3.46) and HFR% was(1.15±0.78).Conclusion The reference limit for six parameters of reticulocyte count are different according to sex,apparatus and so on,and laboratory should establish their own reference limit according to the specific conditions.RET# between male and female in healthy children doesn't show significant difference,and reticulocytes subpopulation is not correlated with sex.
