杭州地区2～6岁健康儿童血清垂体一甲状腺轴激素正常参考范围调查

A survey on reference ranges for serum pituitary-thyroid hormones of 2-6 years old healthy Chinese children in Hangzhou

用化学发光法检测592名杭州地区2～6岁健康儿童的血清TSH、T3、T4、FT3、FT4浓度并作统计分析,得出总人群的正常参考范围为：TSH 1.09～4.60 mIU/L,T3 1.17～1.95μg/L,T4 57.43～99.60μg/L,FT3 5.35～7.50 pmol/L,FT4 13.96～19.70 pmol/L.不同年龄、不同性别间比较,差异无统计学意义（P＞0.05）.

Serum concentrations of TSH, total and free thyroxine, and total and free triiodothyronine in 592 healthy children aged 2-6 years were determined by means of ADVIA Centaur. The normal reference ranges were calculated. The reference ranges of TSH, T3, T4, FT3, and FT4 were 1.09-4.60 mIU/L, 1.17-1.95 μg/L,57.43-99.60 μg/L, 5.35-7.50 pmol/L, 13.96-19.70 pmol/L, respectively. There was no significant difference in the interval of thyroid hormones between males and females as well as among different age groups.
