What a beautiful age:)
In some cases the radioactive iodine causes flaring of hyperthyroidism (if patient has Grave’s disease or Hot nodule), however Technetium-99 scan seems not to have such bad effect, particularly for the toxic nodules. It almost follows the distribution pattern of the Iodine, and is short acting (so the results could be received much faster in few hours). It also easier on kidneys then Iodine;in addition the ultrasound for thyroiditis at later stage may show a "gainy" or "coarse" image of the thyroid tissue.
Thank you! I'm not sure if they have tested me for the TSI antibodies yet but I do remember the dr mentioning it in tests that need to be run. I have been so out of it lately, I forgot to ask about it the last time I was at their office. Also, is there a reason they haven't done the uptake test yet? They keep telling me they want me to stabilize and go through a cool down stage before they do it. But I haven't read about a "cool down stage" on any forum or website. I'm just so impatient and want to know the cause of all this mess so I can get it under control! By the way, I'm 28 years old.
The doctor should order a blood test for the TSI antibodies; if they are present (unless you are over 60) you most probaly have a Grave's. Also, the less reliable sign of the Grave's disease is a very intense blood flow in the entire thyroid detected by Doppler flow ultrasound.
The nuclear test and the antibody tests are the sttundard tests for Grave's disease.
Good luck!
