What does high thyroxine mean?

Thyroid hormone is a hormone secreted by the thyroid gland. It includes total thyroxine and free thyroxine. High thyroxine indicates possible hyperthyroidism, which should be judged in combination with total t3, free t3 and tsh. If thyroxine is high, t3 is also high, and tsh is low, it indicates hyperthyroidism. Antithyroid drugs such as propylthiouracil or tapazole should be given. The above health science knowledge is for reference only. The specific situation needs to be checked in a regular hospital and judged by a professional doctor. Do not diagnose or treat yourself.
