摘要 目的 建立北京和上海地区表面健康人群血清三碘甲状腺原氨酸(TT3)、甲状腺素(TT4)、游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)、促甲状腺素(TSH)的参考区间.方法 按照美国国家临床生化学院检验医学应用准则中关于甲状腺疾病诊断与监测的实验室支持中的筛选要求,在北京、上海地区筛选体格检查和相关实验室检查均正常的表面健康人群390名(男221名,女169名),年龄18 ~ 65岁.采集受检者空腹血清,使用美国UniCel DXI 800全自动化学发光分析仪进行TT3、TT4、FT3、FT4、TSH的检测.不同性别、地区间上述各种甲状腺激素水平的比较采用两独立样本t检验,不同年龄组间的比较采用方差分析,两两比较采用LSD法.参考区间采用P2.5~P97.5表示.结果 对各种激素水平进行性别间比较,男性组TT3、TT4、FT3、FT4、TSH水平分别为(1.90±0.32) nmol/L、( 116.77±18.02) nmol/L、(5.28±0.67) pmoL/L、(11.54±1.97) pmol/L、(1.92±1.12) mIU/L,女性组分别为(1.82±0.32) nmo]/L、( 115.73±14.39) nmol/L、( 5.04±0.59) pmol/L、( 10.94±1.45) pmol/L、(2.37±1.86) mIU/L,TT3、FT3、FT4、TSH差异均有统计学意义(t分别为2.377、3.642、3.471、2.520,P均<0.05).不同地区间结果比较,只有FT3在地区间差异有统计学意义,北京和上海分别为(5.01±0.63)、(5.41±0.61) pmol/L(t =6.410,P<0.01),其他指标差异均无统计学意义.相关分析结果表明,TT4与年龄呈正相关(r=0.22,P<0.01);TSH与年龄呈负相关(r=-0.12,P<0.05).TT3、TT4、FT3、FT4、TSH参考区间分别为(1.22 ~2.50) nmol/L、(83.37~149.37) nmol/L、(3.88 ~6.48) pmoL/L、(7.70~14.86) pmol/L、(0.38 ~5.58) mIU/L.结论 北京和上海地区人群血清甲状腺激素水平与进口试剂盒给定的参考区间有差异,建立我国甲状腺激素参考区间具有重要意义. Objective To establish the reference intervals of serum triiodothyronine (TT3),the thyroxine ( TT4 ),free triiodothyronine ( FT3 ),free thyroxine ( FT4 ) and thyroid-stimulating hormone (TSH) in the apparently healthy individuals of Beijing and Shanghai.Methods According to the requirement for laboratory support for the diagnosis and monitoring of thyroid diseases in the National Academy of Clinical Biochemistry (NACB) laboratory medicine practice guidelines, there were 390 apparently healthy individuals tested (221 male,169 female,18 -65 years old) from Beijing and Shanghai for serum TT3,TT4,FT3,FT4 and TSH on American Beckman UniCel DXI 800 Automatic Chemiluminescent Analyzer.All markers were analyzed between gender,region,age group using t test and ANOVA.The reference intervals of all markers were determined by P2.5 - P97.5.Results TT3,TT4,FT3,FT4,TSH levels in the male group were ( 1.90 ± 0.32) nmol/L,( 116.77 ± 18.02) nmol/L,( 5.28 ±0.67) pmol/L,( 11.54 ± 1.97) pmol/L,( 1.92 ± 1.12 ) mIU/L,respectively,while the above indicators in the female group were ( 1.82 ± 0.32) nmol/L,( 115.73 ± 14.39 ) nmol/L,(5.04 ± 0.59 ) pmol/L,( 10.94 ± 1.45) pmol/L,( 2.37 ± 1.86 ) mIU/L,respectively.When comparing the results in genders,statistical significance was shown in TF3,FT3,FT4 and TSH of two gender groups( t =2.377,3.642,3.471,2.520,all P 〈 0.05 ).When comparing different regions,statistical significance was only shown in FT3 ( t =6.410,P 〈 0.05 ),in which Beijing group was (5.01 ± 0.63) pmol/L,and Shanghai group was (5.41 ±0.61 ) pmol/L,and no significant difference were shown in other four markers.Correlation analysis showed that TT4 was positively correlated with age (r =0.22,P 〈 0.001 ) while TSH was negatively correlated with age ( r =- 0.12,P 〈 0.05 ).TT3,TT4,FT3,FT4,TSH reference intervals were ( 1.22 - 2.50 ) nmol/L,(83.37 - 149.37 ) nmol/L,( 3.88 - 6.48 ) pmol/L,( 7.70 - 14.86) pmol/L,( 0.38 - 5.58 ) mIU/L,respectively.Conclusion Differences of serum thyroid hormones were observed in different areas of China,It is important to establish reference intervals of the serum thyroid hormones in Chinese population.
