Would you agree with the following statement (from the STTM)?
From STTM: FREE T4: T4 is the thyroid storage hormone. Free in front of the T4 means you are measuring what is available and unbound. Generally, those on an optimal amount of desiccated thyroid will have a free T4 around mid-range when their free T3 is at the top and in the presence of healthy adrenals. If you have low FT4 and a mid-range or slightly higher FT3, it usually means the T4 is converting like mad to give you the T3 you do have, which means hypo.
