Investigation of blood calcium and iron reference intervals of pre-school age children in Yongkang

Objective To study and establish the reference intervals of blood iron（Fe） and calcium（Ca） of pre-school age children in Yongkang and investigate the correlation with sex.Methods The concentrations of Ca and Fe in the whole blood of 1 147 children（618 male and 529 female） were measured by flame atomic absorption method,and the results were analyzed statistically.Results The reference interval of Fe was 6.99-9.14 mmol/L（male： 6.97-9.04mmol/L,female： 7.04-9.21 mmol/L）.The reference interval of Ca was 1.43-1.99 mmol/L（male： 1.42-2.02 mmol/L,female： 1.43-1.94 mmol/L）.The reference intervals of Fe and Ca had no difference with sex.Conclusions There is no need to use different reference intervals of Fe and Ca according to sex.The reference intervals in the study were agreed with the population characteristics of pre-school age children in Yongkang.They can improve the clinical diagnosis accuracy instead of using the reference interval from reagent companies.
