Cathryn, triiodothyronine is T3. Yours is WAY above the normal range, which is consistent with hyperthyroidism.
The thyroid produces some T3 (and maybe LOTS when it’s wacko from Graves’), and if your T4 is sky high, the T3 would be even higher, since T4 is converted to T3 in body tissues.
In other words, yep–you’re WAY hyper!
