My Sister has hashi and is hypo. She is currently taking .135 Synthroid I think. She just had labs done and these are results:
TSH 1.04 (.45-4.5)
FT3 3.4 (2.0-4.4)
FT4 1.93 (.82-1.77)
TPO 105 (0-34)
I told her I thought she should get her FT3 up a bit since it isn't in upper range. I also told her she needed to get her vitamins and minerals in balance. This was her annual and doc didn't even order vitamin D. I know she has been on the low side for vitamin D before.
What would/could cause FT4 to be over range?
She couldn't get the doc to do RT3 but will order the test privately.
Any advice would be appreciated.
