Thyroxine Vs Triiodothyronine
Can any doc tell me what's the difference between thyroxine, thyrocalcitonin and triiodothyronine?
Yes: Thyroxine also known as T4 is the main product of the thyroid gland. Triiodothyronine or t3 (liothyronine) is also a product of the thyroid but most of it comes from the conversion of T4 in the human tissues by the enzyme deiodinase.

Thyrocalcitonin or just calcitonin is unrelated to the above two, comes from the c-cells, and affects the calcium level. ...Read more

Every lab also has a slightly different 'normal' range depending on how they measure the hormone. Seeing the trend also helps - Are they stable, going up or down? ...Read more
