Thyroiditis: Why are you having your thyroid tested? what are your symptoms? start from the begining. Medicine is not about scans and numbers. TSH is suppressed by the elevated T3 (liothyronine) as feedback inhibition. I would expect normal to high uptake but it can be low in some cases of Hashimoto's thyroiditis. thyroid scan in Hashimoto's thyroiditis can mimic a wide range of thyroid disorders. Thyroid may be burning out.
