I've been told that only activeT3 determins the level of TSH productio

Sent to Health Experts October 13, 2006 11:26 a.m.

Is T3 the only thing used in the feedback path to the hypothalamus/pituitary gland mechanism that produce the TSH? Are the T4 or reverse T3 (RT3) components involved?

Thanks for your help.

ACCEPTED

Both T 3 and T 4 have a negative feedback loop in the hypothalamus/ pitutary axis. The RT3 has no role in this cycle.
