thyroid stimulating hormonefree T4blood

Thyroxine (T4) is one of two major hormones produced by the thyroid gland and is primarily used to indicate thyroid disorders. Increased levels of T4 may indicate hyperthyroid conditions such as Grave’s disease, toxic multinodular goiter, subacute or chronic thyroiditis, early Hashimoto’s disease, iodine-induced hyperthyroidism, germ cell tumors, and trophoblastic disease. Decreased levels of T4 indicate hypothyroidism. T4 is a useful marker for the diagnosis of hypothyroidism and hyperthyroidism and can be used to monitor effectiveness of treatment of a thyroid disorder.
