测定血清铁含量有助于了解人体铁的吸收、利用、贮存及排泄的动态平衡。1987年春笔者曾对郑州四中一至五年级12～16岁的男生随机抽取150名,按常规采集血清及预处理,用北京产WFD—Y_2型原子吸收分光光度计实测118名学生血清铁含量。仪器的变异系数(CV)为4.3％,回收率为92.6～103.6％,线性关系较好。结果(见表):经相关及方差分析,血清铁并不随年龄增加而升高(P>0.50),各年龄组血清平均含量差别无显著性(P>0.05),这与王秀云等(《微量元素》杂志,1988年第一期44～74页)报导不一致。
Determination of serum iron content helps to understand the human body’s absorption, utilization, storage and excretion of the dynamic balance. In the spring of 1987, 150 boys from 12 to 16 years old from grade 1 to grade 5 in Zhengzhou were randomly selected and serum and pretreatment were collected routinely. The serum iron content of 118 students was measured by Beijing WFD-Y_2 atomic absorption spectrophotometer. The coefficient of variation (CV) of the instrument is 4.3%, the recovery rate is 92.6 ~ 103.6%, and the linear relationship is good. Results (Table): Serum iron did not increase with age (P> 0.50) by correlation and analysis of variance (ANOVA), but there was no significant difference between groups (P> 0.05) Elemental Magazine, 1988, pp. 44-74) reported inconsistent.
