Question about lab results and further tests

[Ginny2008]

Hi, I am a 41 year old female.  I just had bloodwork results- Free T4 is 1.20, TSH is .195 and Free T3 is 3.3. I had an ultrasound done at the endocrinologist office and he said there are nodules on my thyroid gland. He has scheduled me to have the radioactive iodine uptake test this Friday.

My question is this, do I need to have this test done?  What is the benefit of having it done vs the risks since I am mildly hyperthyroid?  

Thank you.

The iodine uptake scan allows the doctors to see if your thyroid is overactive and what is hapening. The best I can describe it is that they give you a generous idodine dose in pill form then scan your neck to see what the body did with the dose. If your thyroid is overactive after 24 hours when they x-ray your thyroid gland it will show that all of the idodine is hanging out in your thyroid. I am sure the doctor can explain it better.

What does the Iodine uptake do?

So the ultrasound showed nodules? Does it describe them? I recently had an U/S - I didn't even know about thyroid problems until about a week ago! I had just noticed vague/small lumps on both sides of my neck after a bout of a virus. I went to my GP and the ultrasound said 'solid nodule with hypoechoic halo' etc. etc. I'm having a biopsy next week. Are u scheduled for one?

I had no adverse reactions to my thyroid uptake and its best to see what is going on. If there is a problem you will get progressively worse, so its best to catch it early. Good for your doctor.
