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.

OOOPs!

Correction: 'Treatment for hyperthyroidism is diagnosed at
TSH level 0.1 or less.'

Sorry about that! I had a Graves' Brain moment.

The iodine uptake is usually done in conjunction with blood tests and is done to diagnose thyroid function problems, such as hyperthyroidism caused by certain conditions as,  inflammation of the thyroid gland (thyroiditis), recently taking too much thyroid medication, or another rare condition. However it can't tell how hyperthyroid a person is, only blood test can tell that.  It can also show areas in the thyroid gland where the activity is less than expected (cold nodules) or more than expected (hot nodules). Cold nodules may be associated with thyroid cancer.
Your blood test  might relate to other possible issues such as Hypothyroidism due to low pituitary function, adrenal fatigue or other problems such as allergies, hormonal imbalance, yeast, etc. The Uptake hopefully will reflect more on what your issues are, if there is any. Treatment for hyperthyroidism is diagnosed at THS 0.01 or less.

Good luck!
