目的:调查健康人体血清中铁和钙的正常水平,确定健康人群中的血清铁和钙含量参考值范围,探讨性别和年龄因素对健康人群体内血清铁、钙含量的影响。方法:在健康人群中随机选择440名受试者(男147名,女293名),取清晨空腹血,并对样本进行微波消解,消化后的样品用火焰原子吸收方法进行检测,对检测的样本进行统计分析,确定人群血清铁血清钙正常参考值。结果:正常人体血清铁和钙正常值范围分别为:1.10~1.60 mg/L和101.31~140.27 mg/L。血清钙男性组高于女性组,而血清铁男女之间差异并没有统计学差异。这两种元素在年龄组间均无显著统计学意义。结论:与其他地区的研究调查相比,济南地区人群的血清铁含量较低,而钙浓度较高。
OBJECTIVE: To investigate the normal levels of iron and calcium in healthy human serum and to determine the range of reference values of serum iron and calcium in healthy subjects and to explore the effect of gender and age on serum iron and calcium levels in healthy subjects. METHODS: A total of 440 subjects (147 males and 293 females) were randomly selected from healthy subjects. Fasting blood samples were taken from morning to morning and samples were digested with microwave. The digested samples were detected by flame atomic absorption spectrometry. Samples were statistically analyzed to determine the normal reference serum iron serum calcium. Results: Normal human serum iron and calcium ranged from 1.10 to 1.60 mg / L and from 101.31 to 140.27 mg / L, respectively. The level of serum calcium in male group was higher than that in female group, while there was no significant difference in serum iron level between male and female group. There was no statistically significant difference between the two age groups. CONCLUSIONS: Compared to studies in other regions, serum iron levels in Jinan are lower and calcium concentrations are higher.
