When on combination hormone replacement, we're all different as to where we need our FT4. Some are fine with it lowish in range, some of us need it higher in range, so it's up to us to tweak our doses and find out for ourselves which is the optimal dose of each hormone for us to feel well. I can't tell you if your FT4 is high enough, only you will know that.
Was test done as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test and last 1/3rd of daily dose of T3 between 8-12 hours before test?
As Seasidesusie says ...ft3 only 55% through range and Ft4 is only 50% through range
