What are normal levels of Thyroxine (T4). I have been told that mine is 14.6 and that normal is anywhere from 5-12. Is this correct even with thyroid cancer patients? In 2/05 I had a total thryoid removal and later had radioactive iodine treatment. I was going to an endo, but was later told that my family doctor could handle long term care. I guess I just get a little nervous that my family doctor will not know how to interpret my test results. I have to go to follow up visit, but I just wanted to know what this T4 level meant before going into the appointment. Please help.
