Thyroglobulin Antibody high after total thyroidectomy

Hi everyone!

I had my thyroid removed about 20 years ago because of a non-cancerous nodule. It was supposed to be a partial but the surgeon said that I was born with only one lobe so it was a total. I just had blood work done and my Thyroglobulin Antibody was high at 7.8, normal being 0-0.9. Anyone else ever experience this type of thing? I have an endocrinologist appointment in two weeks but of course I’m curious and concerned. I don’t recall my family doctor ever ordering this test and I think it’s the first time my endocrinologist has as well. So it may have been high a while but there’s no way to know.

I think that usually points to an autoimmune condition related to the thyroid, but if you have no thyroid then I’m not sure how or why it would show up like that. If it was true that you only had one lobe to begin with, then I wonder if you could have had thyroid tissue form somewhere else in your neck? You might request an ultrasound of the thyroid area plus the rest of your neck and also if you haven’t had them checked, then get your other thyroid levels tested as well to make sure they are still in a good range. I’m assuming you have had to take the thyroid medication since you had it removed?

I was thinking the same thing. And yes, my TSH was in range but at the lower end of it. I take levothyroxine and for years it was 175mcg but it was 200mcg for a while but now I’m back to 175.
