Reference value: FT3: 3.1–6.8 pmo/L, FT4: 12–22 pmo/L, T3: 1.3–3.1 nmo/L, T4: 62–164 nmo/L, TSH: 0.270–4.20 mIU/L, TPOAB: 0–115 IU/mL, TGAB: 0–34 IU/mL.

FT3 = free triiodothyronine, FT4 = free thyroxine, T3 = triiodothyronine, T4 = thyroxine, TGAB = anti-thyroglobulin antibodies, TPOAB = thyroid peroxidase antibody, TSH = thyroid stimulating hormone.
