Now, my understanding was that all T3 (bound and unbound)
is produced from Free T4. Well, you can see that my Free T4
is 1.41 ng/dL, and that my Total T3 (bound and unbound) is 106 ng/dL. Obviously, the amount of Total T3 is far greater than the amount of Free T4. So, is all T3 (bound and unbound) produced from Free T4? Or is there another source of T3?
Thank you for any info.
