Primary hyperthyroidism is accompanied by elevated serum FT3 and FT4 levels along with depressed TSH values.
Normal FT4 levels are accompanied by increased FT3 in patients with FT3 thyrotoxicosis.
Slightly elevated FT3 levels may be found in pregnancy and estrogen therapy, while depressed levels may be encountered in severe illness, renal failure and during therapy with drugs like propranolol and propyl thiouracil.
