Labs

I thought I was only having my TSH level taken, but blood was also drawn for my Thyroglobulin level (Tg), which I believe is the tumor marker for thyroid cancer. Little surprised that a Thyroglobulin antibody test (TgAb) was not also part of the blood work taken, although perhaps it is something that will also be analyzed along with the Thyroglobulin level. Or maybe not - further research on the TgAb indicates that I would have been told to fast for several hours before the test, which I was not told to do and was not asked about when I checked in at the lab. I hope I didn't botch up my labs!

Just days away from my RAI therapy dose, and I noticed that the TJ's blue corn tortillas I've been eating are processed on machinery shared with soy and dairy products. Great. Could I be botching up my chances for a good RAI therapy and whole body scans?!? I know I need to stop stressing, but I'm starting to get worried about how good I've been about following the low-iodine diet (from hell) these past couple of weeks and that my TSH and Tg levels are where they need to be. Argh!
