Hey all, a few months ago I had a blood draw and my new doctor decided to up my levothyroxine from 50 mcg to 75 mcg. I find the before and after results curious. I would like to know what any hypo people here think. Blood lab at 50 mcg: -TSH 2.1 -free T4 1.65 ng/dl -T3 115 ng/dl (I think this was a TOTAL T3 measurement) Blood lab after 7 weeks on 75 mcg: -TSH 1.3 -free T4 1.48 -T3 113 Makes sense that TSH lowered obviously, but I don't understand why the actual thyroid hormones lowered a bit. maybe it's just normal day to day variation? My free T4s are about 7 units under the very upper range, and my T3s are in the lower quarter of the range. So, upping my levothyroxine didn't seem to have any effect on T3 production. I find this all very interesting considering I'm back in another TE phase for the past couple months.
