I just got back test results EXACTLY like these. My TPOab is normal, but TGab is 3.5 (0.0 - 0.9). TSH is fine, fT4 is fine, fT3 is normal, but lower than it had been previously. I've also been gaining weight rather quickly for the first time in my life (32 yrs old). I had my selenium levels checked a few months ago and they were fine. Plus, I was taking 25 mg Iodoral and 2-3 brazil nuts every day. Any more ideas??
