Hyperthyroidism ?: High T3 (liothyronine) means hyperthyroidism or thyrotoxicosis depending on severity. You should seek an endocrinologist to decipher etiology of such elevation and if you need thyroid scan to come with an accurate diagnosis. If you are a female and in pubertal/post pubertal range, the odds are in favor of graves' disease being the mostly likely cause. Females: pregnancy test recommended.

More info needed. What are TSH, T4 and b-hcg levels? Do you take levothyroxine? Do you take liothyronine? I agree you should talk with your primary care doctor get referred to an endocrinologist.

T3: An elevated t3 is seen in overactive thyroid but other thyroid results are needed for confirmation. These include an elevated t4 and a very low TSH level as well before the diagnosis of hyperthyroidism is accepted.
