Re: Thyroglobulin test result
From what I understand it could just be residual TG that soon after the thyroid removal. When they remove the thyroid there is not guarantee that all the thyroid tissue is removed, since it could be on parathyroid gland, nerves, vocal cords. That is the reason for the RAI, to kill the remaining tissue. After the RAI, if the TG is still high there is a cause for concern.
