Traceable Tg, Whole Body Scan Neg

I am 5 yrs out from treatment of papillary thyroid ca, total thyroidectomy and I131. Had extrathyroidal extension, positive margins and multiple lymph nodes pos.  On routine yearly followup my endocrinologist suggested one last TSH supression, which ended up showing traceable Thyroglobulin. I went for WBS and it was neg. My physician's office says no further follow up needed, continue levothryoxine and see 'ya next year.  I'm confused about the traceable Thyroglobulin.  It's never been traceable before. Just about everything I've read says traceable Tg usually means a recurrence. Does anyone have any suggestions?

Hi there!

Traceable thyroglobulin does not specifically imply a recurrence. Thyroglobulin may be normally present, while only elevated levels would be suspicious of a recurrence and unless mentioned by the treating doctor, this would not be anything to worry about.
Hope this is helpful.

Take care!

That's what I've been told, too by my Endo.  Mine has gone up and gone down but nothing drastic and within limits for what the expect to see since I had a partial thyroidectomy with micro-papillary on the removed side.
