There isn't a hard and fast relationship between total and free T3 (or between total T4 and free T4 for that matter). If you have a lower amount of the proteins that carry total T3 and T4 around in your blood, which the tissues sample through FT3 and FT4 as the proteins pass by, then the T3 and T4 reservoir is smaller. But this smaller reservoir can still give a correct FT3 and FT4. Some people have large amounts of carrying proteins with big T3 and T4 reservoirs, but they can still give the same FT3 and FT4.
Thanks for the explanation I really appreciate it. So I shouldn’t base a dose increase on my Total T3 being low?
I feel the pressure to increase my Armour dose. No thyroid and only on 90 mcgs of Armour seems low to many’s standards. And I do have some lingering symptoms that flare up.
