I just got my TSH results back from the dr and it was .57 which I know is still within the normal range. However I had the TSH a year ago and it was .9 and then in Jan. it was .8. I am wondering since I had to have a CT Angiogram 4 weeks ago with an Iodine contrast, would the iodine lower or raise one's TSH level?
I forgot to tell the dr about the CT scan and saw on a website that the iodine can affect the TSH level 4-6 weeks after the test.
Any input on this would be really appreciated.
I ask because I have shown some symptoms for hyperthyroidism but my levels look normal.
