Elevated Thyroglobulin caused by Stress? Other Factors?

[65sportsmom65]

My thyroid was removed in 1996. Have had regular follow-up visits and peroidic bloodwork. 3 years ago, had some elevated Thyroglobulin. Ultrasound showed a tiny spot near windpipe, and some scar tissue and Misc "trash". Biopsy of one spot was negative.As precaution, underwent radioactive ablation, high dose. Subsequent ultrasounds have been normal. Thyroglobulin levels have fluxuated, rising somewhat during periods of heavier-than-normal stress. Most recent ultrasound shows unknown oval spot. Doc suggests ct scan, or to go back to specialist that performed previous ultrasound and biopsy for repeat. Suggestions? This has me nervous now. Praying for answers and peace.

Why was your thyroid removed in the first place?  

I can't find references to thyroglobulin levels rising during periods of stress, though I won't say they can't.

While I don't want to make you more nervous, typically, Tg is used as a cancer marker, with levels staying low when cancer is not present.  I suggest that you go back to the specialist (if you felt comfortable there) and see if a biopsy would be called for vs a CT.
