My doctor told me today that I can't have a follow up (6 month) scan (I am finishing up a RAI treatment) after have a CT with contrast until 2 months after the CT. Instead, we're going to schedule my scan for before the CT. (We have enough time to do that). Prior to doing the initial scan and RAI treatment, I had to be on a low iodine diet for a week or two.
All that said, I'm not sure if the iodine levels will change the blood test. I've never been told to avoid iodine prior to having labs done, and my doctor is pretty thorough.
