目的研究甘肃兰州地区妇女妊娠各期血清甲状腺激素医学参考值范围。方法收集2015年10月至2016年6月在兰州大学第二医院妇产科门诊产检的单胎妊娠健康孕妇562例,其中孕早期(T1)238例,孕中期(T2)192例,孕晚期(T3)132例;选取52例非妊娠健康育龄期妇女作为对照组。用Siemens ADVIA Centaur XP检测仪化学发光法检测甲状腺激素(thyroid-stimulating hormone,TSH)、游离甲状腺素(free thyroxine,FT_4)和游离三碘甲状腺原氨酸(free triiodothyronine,FT_3),并对结果进行统计分析,建立该地区妊娠期甲状腺激素医学参考值范围。结果甘肃兰州地区妊娠期TSH参考值范围在孕早、中、晚期分别为0.05~5.58 mU/L、0.26~4.80 mU/L、0.21~5.11 mU/L;FT_4在孕早、中、晚期分别为10.73~19.15 pmol/L、10.26~18.06 pmol/L、9.94~16.35 pmol/L。TSH在孕早期最低,FT_4最高,妊娠各期参考范围有差异,孕期与非孕期参考范围存在差异。结论建立甘肃兰州地区妊娠期甲状腺激素参考值范围十分重要与必要。
Objective To study the serum thyroid hormone reference value of pregnancy in Lanzhou women in Gansu province. Methods A total of 562 pregnant women with singleton pregnancies undergoing maternity check-up were collected from October 2015 to June 2016 in the Second Hospital of Lanzhou University. Among them, 238 were pregnant in the first trimester (T1), 192 were in the second trimester (T2), and the third trimester was in the third trimester (T3) 132 cases; 52 non-pregnant women of childbearing age were selected as the control group. The thyroid-stimulating hormone (TSH), free thyroxine (FT_4) and free triiodothyronine (FT_3) were detected by chemiluminescence method with Siemens ADVIA Centaur XP detector and the results were analyzed Statistical analysis, the establishment of the region of pregnancy thyroid hormone medical reference value range. Results The reference value of TSH during pregnancy was 0.05-5.58 mU / L, 0.26-4.80 mU / L and 0.21-5.11 mU / L respectively in pregnant women in Lanzhou district in Gansu province. The levels of FT_4 in early, middle and late pregnancy were 10.73 ~ 19.15 pmol / L, 10.26 ~ 18.06 pmol / L, 9.94 ~ 16.35 pmol / L. TSH lowest in the first trimester, FT_4 highest, the reference range of pregnancy differences, pregnancy and non-pregnancy reference range are different. Conclusion It is very important and necessary to establish the reference range of thyroid hormone during pregnancy in Lanzhou, Gansu Province.
