Why did he test TRAb versus TGAb? TRAb is an indicator of Graves.. the most inaccurate test for it. TSI is more reliable and TGAb is the Hashimoto's equivalent to the TRAb.
Thyroxine (T4) free, direct, s - 1.22 (0.61-1.76) = 53% This is just inside the 50-80% optimal window so if you are still hypoT feeling you could tolerate a slight nudge in dosage.
TSH - 1.431 (0.350-5.500) = optimal is between 0.89 - 1.1.. by this I think the TSH is telling you your optimal is a bit higher in the range.. but you are getting close.
Thyroid Peroxidase (TPO) Ab - <10 (0-34) = congratulations you do not have Hashimoto's TPOAb antibodies of significant concentrations to screw with you! You need the TGAb to completely rule it out though.
Thyroidothronine, Free, Serum - 3.2 (2.3-4.2) = 47.3% This is with in 5 % of your T4 levels which indicates you are balanced.. however it is a smidge below optimal and IMO if you still feel a tad hypoT you should ask for a trial boost. My family feels best in the 65-75 % of normal range. You are just at the bottom of the optimal window.
