Comparative analysis of thyroid function parameters in pregnant women

摘要: The aim of the present study was to investigate serum levels free triiodothyronine (FT3), thyroxine (FT4) and thyroid stimulating hormone (TSH) during pregnancy comparative analysis markers in non-pregnant women pregnant women. Pregnant were divided into four groups according their gestational age: 8-14, 15-20, 21-36 ≥37 weeks. Non-pregnant three 20-40, 41-55 56-85 years, reproductive age (20-40 years) as control, which match body mass index with measured by magnetic microparticle chemiluminescence immunoassay compared among different weeks or control. In women, from 8-14 weeks, FT3 FT4 declined, significant differences identified between each group, except for at when While TSH increased group. Compared control concentrations FT3, lower all Reference intervals are much than that likely have throughout pregnancy. current reference hormones not feasible pregnancy-specific should be established a local Chinese database.
