Re: Thyroglobulin levels..... What to expect?
It takes several months for RAI to work.
I didn't have any follow up for a year, I had one wbs after one year, and then only test my thyroglobulin every six months, and have a neck ultrasound and no more wbs.
Every doctor has different protocols. The main thing is not your baseline thyroglobulin (it just measures thyroid tissue which of course you would have before rai), but that you need to know if you have thyroglobulin antibodies to see if thyroglobulin will be a good marker for you or not.
You would want after a year, your thyroglobulin to be "undetectable" if possible.
