Serum tests. Serum thyroglobulin fluctuated insignificantly with sustained suppressed TSH before, during and after pregnancy. Square frame represents the period of pregnancy (Jan. 2014-Sep. 2014). FT3, free triiodothyronine (normal: 3.67–6.00 pmol/L); FT4, free thyroxine (normal: 7.50–21.10 pmol/L); TSH, thyroid stimulating hormone (normal: 0.34–5.60 mIU/L); Tg, thyroglobulin (normal: 3.50–77.00 ng/mL); TgAb, anti-Tg antibody (normal: 0.00–115.00 IU/mL); TT3, total triiodothyronine (normal: 1.13–2.42 nmol/L); TT4, total thyroxine (normal: 75.37–167.78 nmol/L)
