Re: t3 and t4

Shoot, I was afraid of that. I was go glad my PCP was ordering all these labs when my TSH was normal that I forgot to ask him specifically for *free* T3 and T4! Will I have to ask him regardless? I supposed sometimes things will show in the total? I read about the T3 and T4 connected to proteins not being available to tissue, but elsewhere by a scientist I read that there's an enzyme that cleaves the hormone from the protein when it's need at a site. Don't know what to think now.
