Actually, I am not taking T3. I have been on T4 for 6 weeks and just had my FT3 checked. Two months ago, before starting on T4, my labs were as follows
FT4 0.9 (0.9-1.8)
TT3 87 (80-180)
Did not measure FT3, even though I asked for it
One week later
FT4 1.2 (0.9-1.7)
One month later, after being on synthroid 25 mcg
FT4 1.2 (0.9-1.7) unchanged
TT3 90 (80-180) unchanged
FT3 2.0 (1.8-4.2) low
I only show you all 3 here because I wanted you to see that a low dose of T4 was not what raised my FT4, as it had jumped to that number the month before. The only thing it appeared to do was suppress my TSH a bit.
