Changes in mean concentration of thyroid function tests on Abbott Architect 2000 before and after the withdrawal of biotin from 10 participants. Tg and anti-TSHR are no available in the Abbott Architect 2000 test menu. To convert free T3 from pg/mL to pmol/L, multiply by 1.54; free T4 from ng/dL to pmol/L, multiply by 12.871; total T3 from ng/mL to nmol/L, multiply by 1.54; total T4 from μg/dL to nmol/L, multiply by 12.871. Anti-TPO = antithyroid peroxidase antibodies, anti-TSHR = thyroid-stimulating hormone receptor antibody, T3 = total triiodothyronine, T4 = total thyroxine, Tg = thyroglobulin.
