What is the definition or description of: ft4/tsh/ft3?
A doctor has provided 1 answer
See answer details.: Thyroid stimulating hormone (TSH) is produced by the pituitary gland and stimulates the thyroid gland (in your neck) to produce the thyroid hormone thyroxine (t4) which is then converted into triodothyronine (t3) which is the active hormone that stimulates metabolism. Both T3 (liothyronine) and T4 are mostly bound to thyroid binding globulin, but free (unbound) amounts exist in your blood; these are ft3 and ft4.
