thanks it was helpfull , is there a need for me to test FT3 , since so many memrbers speak about it and its importance? and another qustion : when in februaty THS came down to 0.23 (o.4-3.8) was it proper to put me for 6 weeks on 0.75 mcg of tyroxine? thanks again Dr. Lupo

Seems like the 100mcg dose seemed on target in terms of TSH and goiter size.  The thyroid antibodies indicate that Hashimotos' is the cause of the hypothyroidism/goiter - there is no need to keep testing the antibodies.
