Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...Read more
Hormones: A tropic hormone is a hormone secreted by one gland and then stimulates another gland; for example, the pituitary makes TSH, which targets the thyroid and causes the thyroid to make T4 and T3 (liothyronine). The thyroid hormones (T4, T3 (liothyronine)) target other organs (heart, CNS, GI, etc), but not really other glands, so are not really tropic hormones. ...Read more

Levothyroxine.: Levothyroxine, generic form of synthroid, has many advantages over armour thyroid. The armour product has significant batch to batch variation and has T3 (liothyronine) in it. Since the T3 (liothyronine) portion of armour has a very quick onset and short duration, it can wreak havoc with the ability to effectively treat hypothyroidism. Until there is a long-acting form of T3 (liothyronine) available, stick to levothyroxine. ...Read moreSee 1 more doctor answer

For hormone tests, however, results have to be interpreted in the context of what is happening clinically. Expected values for someone who is pregnant, or on birth control pills, or who should be ovulating at the time could all differ. ...Read more
