摘要
本文报告536例正常小儿全血锌原卟啉的测定值.结果显示,不同年龄小儿血锌原卟啉值有所不同,随着年龄增长,血锌原卟啉值有逐渐下降趋势。本组小于2岁的锌原叶啉正常参考值为0.7622μmol/L,大于2岁的正常参考值为0.6650μmol/L.男女性别有差异.女性(均值为0.5845±0.1064μmol/L)高于男性(均值为0.5657±0.1115μmol/L),(P<0.05).建议应用血锌原卟啉作为判断红细胞生成缺铁的指标时,应考虑不同地区、不同年龄和性别的差异性.
The values of zinc protoporphyrin (ZPP) in the blood of 536 normal children are investigated. The results show that children of different age have different ZPP values, the older their age, the lower the value of ZPP. The normal reference values in this group are:0. 7622μmol/L (under 2 years) ;0. 6650 μmol/L (over 2 years). ZPP values also vary with sex. The mean value of girls (0.5845?. 1064 μmol/L) is higher than that of boys (0. 5657?.1115 μmol/L)( P <0. 05). Therefore, we suggest that when assessing iron deficiency erythropoiesis with ZPP as an index, we should take into consideration the area, age and sex of the subjects
