Is a person with low FT3, a poor converter, or are there other criterion? What are the factors that make a person a "poor converter"? Clearly if a person has a high FT4 and low FT3, they're likely not converting well. But if a person has a modest let's just say for hypothetical, FT4 1.13 (.82 - 1.77) with a low FT3, does this mean poor conversion is at play? Couldn't it be that this patient doesn't have enough FT4 and needs more t4?
What say you???
Thank you for your time, All.
