I was told this today by my doc during a chekup and she was confused and ordered some appt with nuclear medicine to do some kind of Thyroid uptake thingamajigga?
Anyone off the top of their head, know anything about this?

What were your numbers?
I was told I was hyperthyroid w/ thyroitoxicosis. I suspect my thyroid is fine, but my pituitary is not working right. My TSH was .0X for 3 draws, and the last one it was 1.06 TSH with a T4 of 6, on a scale of 6-12. Weird!
They are probably making sure it isn't auto-immune related, as this can cause odd numbers. They give you a pill of radioactive iodide. They scan you once, then you come back 24hrs later and they scan you again. This lets them literally see what the thyroid is doing. If the TSH is low and the T4 is low, it may be a pituitary problem. I'd get more bloodwork before doing the uptake test. I nearly had that done, but thought it was stupid, as nobody even had a hint as to what was going on. I'm no lab rat
How are you feeling? Thyroid sore at all? How is your FSH/LH and ACTH?
well i dont know anything in this matter but i wish you luck and good health to you and your family Jayhakww. keep us updated.
God bless
Thanks, i don't have the exact numbers in front of me but I do have blood work planned prior to the testing. I have to follow some kind of diet too. I have tremors and hot/cold hands and feet all the time. At night my feet will feel like they are in blocks of ice. I'm a walking symptom right now lol
No dam way I would let them do any RAI on me my wife had this and it killed half her thyroid. Did you do this test * Thyroid Antibodies (anti-TPO and TgAb. YOU NEED BOTH.)
* Ferritin (and do stress FERRITIN, not just RBC)
Additionally, you can have a very low TSH during a one time lab test, yet have an untested high TSH a few days later. That fluctuation is indicative of Hashimoto’s or an attack of the thyroid, causing swings between hypo and hyper.

It is strange because normally with low TSH you would most likely have normal to elevated T4. Nuclear med would most likely be a scan to determine under/over active thyroid.
I am not a physician but I do not think low TSH with low T4 would indicate a thyroid issue as much as it might point towards a pituitary issue.
