Re: Does this make sense?
Good morning. From what I can gather, Thyrogloblin Ab elevates in Hashimoto's. On the other hand, Thyroid perioxidase Ab (TPO) elevates in Hashimoto's, also in Graves Disease, and maybe somewhat in some other autoimmunes; so for it, basic thryoid tests (TSH, T3, T4, etc.) are needed to put the result into perspective.
But I think you said earlier that you're definitely hypothyroid & have taken Synthroid for years... so my guess is that these recent results suggest Hashimoto's---but I'm only a patient, to put it mildly.
I hope people who know these tests better can add to this (I have lupus, it's my sis who has Hashimoto's). And you could also ask on the Thyroid Disorders Board.
Have you returned to the rheumatologist yet? Wishing you more clarity soon, best wishes, Vee
