I started on ndt in July and have my first lab results.
Please see photo for ranges/details.
fT3 dropped from 2.6 to 2.1 and fT4 dropped from 1.2 to .68
So, you would be thinking how dreadful I must feel now? But I feel great for the first time in a long time!
The ft3/rt3 ratio went from 13 to 24. So, I'm sold on the ratio being a big part of the equation. I know that there is disagreement about this, but this is my experience.
Oh, and endo is upping my dose to 2.5 grains...
