TG vs. TG AB?
I am waiting for a call back from my dr. but I'm having some trouble getting this clarified with her. She initially told me that I have elevated antibody levels, but when I got copies of my lab work, it clearly states that both TPO and TG antibodies are in the normal range. It is thyroglobulin (TG) that is elevated. I spoke with the nurse and she was trying to tell me that it's essentially the same thing. My understanding is that it's not. The dr. left a message for me yesterday saying that "only 10% of people with hypothyroid have this AB elevated, as opposed to TPO AB." But I *don't* have elevated AB levels.
I'm a little confused and would like to understand what is really going on before I talk to her tomorrow. For one thing I'd like to have a sense of if she actually knows what she's talking about. I'm not trying to challenge her knowledge, but it seems obvious to me that there's a difference between TG and TG-AB. And that the presence of each would imply a different underlying cause and possibly a different treatment. But I'm not an expert either.
For the record, my TSH is borderline high (it's been between 2.7 and 4.1). FT4 is in the normal range, but low. FT3 is also normal and low, but lower than T4, %-wise.
Thanks for any insight into this.
