The normal level can be up to 11.2. Greater-than-normal levels of T4 along with low levels of TSH may indicate hyperthyroid conditions, such as Graves' disease, toxic multinodular goiter, subacute or chronic thyroiditis, early Hashimoto's disease, iodine-induced hyperthyroidism, germ cell tumors, and trophoblastic disease. Your doctor should do further testing to determine what the exact cause may be.
