T 3 , T 4 , TSH , Zn and copper metabolism in hyperthyroidism and hypothyroidism

We measured serum triiodothyronine (T3), serum thyroxine {14), serum thyroid-stimulated hormone (TSH), zinc (Zn) and copper (Cu) levels in 34 patients with hyperthyroidism, 28 patients with hypothyroidism and 32 healthy subjects. These values were significantly higher than normal in hyperthyroidism and lower than normal in hypothyroidism. There was correlation between serum T3 levels and serum Zn and Cu concentrations in hyperthyroidism. However, there was no correlation among the all other parameters.
