Re: HELP - Confusing Lab Tests HYPO now HYPER
ANA antibodies can be present due to thyroid disease, but they aren't specifically thyroid-related. The test you need to have are TPO (thyroperoxidase), Tg (thyroglobulin), and possibly TSI (thyroid-stimulating immunoglobulin) antibodies. The first two are associated with Hashimoto's disease, which causes hypoT; the TSI are associated with Graves' disease, which causes hyperT.
If you don't have antibodies, nor Hashimoto's, I have a guess about what might've happened.... Only a laywoman's guess that might be theoretically possible, albeit very unlikely. Whatever caused you to become hypo in the first place could have resolved itself allowing your gland to begin working again, either temporarily or permanently; thus, taking the med you no longer need caused you to become hyper.
