TSH is not a cell consumable hormone, its a signal, which is why you also need free T3 and free t4 tested; the hormones your cells use.
Reverse T3 test would be good too. High reverse T3 can block the T3 cell receptors, which can result in "pooling" of t3 in your blood, making you look hyper, when in fact, your cells are hypo. In that case more T3 can unplug the receptors- natural path Drs will do this, Endos dont know this. Ive had this happen at times of high stress and illness, its real, but rare.
Even though the free t3/t4 tests are pretty good, they only show whats available for use. You can pile a kids plate with food, but that wont mean the kid will eat it.
