Abstract
Ten of 25 thyrotoxic patients treated with NaI I-131 had thyroid function test results that indicated a high triiodothyronine (T3) level, with normal thyroxine (T4) and thyroid-stimulating hormone (TSH) levels, within 15 mo. of treatment. This pattern was usually transitional and lasted a variable time, eventually leading to euthyroidism, hyperthyroidism or hypothyroidism. An isolated elevation of T3 levels after radioactive I therapy can be associated with any clinical pattern of thyroid function and has no clear prognostic value. No specific treatment is needed for this abnormality.This publication has 2 references indexed in Scilit:
