In brief: 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.
