Abstract: Objective To establish the normal reference range for serum folate of healthy children in Guangzhou region.Methods Levels of serum folate of 1 860 healthy children (1 061 males and 799 females) and 129 adults (52 males and 77 females) living in Guangzhou region were examined by LK3000V Vitamin Analyzer.Then the data were analyzed with statistical methods.Results ①There was no statistical difference between boys and girls for levels of serum folate in every group defined by age (P＞0.05).②The levels of serum folate [median(P2.5,P97.5)] defined by age were as follows:9.39 (6.12,14.85) nmol/L for 0～1 year-old group,10.65 (6.05,16.52) nmol/L for 1.01～17 year-old group and 11.12 (6.3,17.51) nmol/L for the adult group.Statistical difference was found between any two groups of the three (P＜0.05).③No statistical correlation was found between age and the level of serum folate (r=0.039,P=0.09).Conclusion Reference range for serum folate for healthy children in Guangzhou region include two parts:6.12～ 14.85 nmol/L for 0～ 1 year-old group and 6.05～～16.52 nmol/L for 1.01～17 year-old group.
