Guest guest Posted March 18, 2006 Report Posted March 18, 2006 The TBG test is to test thyroid binding globins..this can be high with estrogen dominance as well as a few other reasons.. I did not mean to come off the wrong way, TSH is Thyroid stimulating Hormone.. T4 is the thyroid storage hormone.. T3 is considered the active hormone that the body uses.. The thyroid produces mainly T4 but some T3, the body then converts T4 to T3. In a thyroid healthy individual this is regulated by the pituary gland that receives a signal from the body to whether or not it needs more or less thyroid hormone and this signal ( TSH ) is then sent to the thyroid to produce more or less hormone. According to bloodwork your body has more than enough T4 and your body is recognizing this but sending out a weak TSH signal..this is why your doctor says you are hyper..too much thyroid hormone.. The problem is you don't feel like too much hormone..remember that T4 is the storage hormone.. A few things can happen..one is you have a high TBG..so your body is holding onto the T4 and not converting it to T3..this can be corrected by either dealing with what hormones or meds are causing the high TBG and/or by adding direct T3 replacement hormone. Another thing that could be happening is something called thyroid resistance in which your body does not know what to do with the hormone replacement..this can usually be addressed by waking up adrenals and going on higher than normal thyroid hormones.. As far as the doc question goes, if they say you are normal or say the opposite of what you are feeling you need to ask them why..usually they will change diagnosis..it is just a matter of getting the info out.. and most docs won't ask..
