Abstract

Several studies have shown that the replacement doses of oral thyroxine are associated with supranormal concentrations of serum T4, although normal concentrations of triiodothyronine (T3) (1–4) and the underlying mechanisms remain debatable. The present study confirms the high serum T4 and normal T3 with the conventional doses of oral T4, but also identifies a greater prevalence of unmeasurable TSH concentration in these patients.
