目的建立妊娠期特异性甲状腺相关指标参考范围,探讨孕早期血清促甲状腺激素
hormone,TSH)参考范围的制定方法。方法收集2013年6月至2014年4月在北

京大学第一医院就诊的早孕妇女548名;筛选上述人群中符合美国临床生化研究院推荐标准:单胎妊娠、无妊娠不良结局及产科并发症的孕妇254名,采用序贯的研究方法建立妊娠特异参考范围。检测
血清TSH、总甲状腺素(rr】:'。)、游离甲状腺素(I■),应用热消解法检测部分孕妇的尿碘水平。本研究
通过北京大学第一医院临床研究伦理委员会审查。结果研究获得的我院妊娠期特异性甲状腺相关指标参考范围如下:T1期参考范围:TSH

比较,孕7—12周组血清TSH水平有降低趋势,但差异元统计学意义(P=0.063)。部分孕妇T1(n=95)、T2(n,=199)、乃(n=70)期的尿碘中位数分别为211.60、195.55、198.65¨∥L,均属于碘适量范围。结论妊娠期妇女血清甲状腺激素水平与试剂盒的参考范围存在差异,且妊娠各期之间亦存在明显不同。在早孕期,分别建立孕4~6周、孕7—12周的血清TSH参考范围可能更为合理。
