I don't use total T3 - it is somewhat irrelevant.

I write about reverse T3 yes. Reverse T3 is important but I don't worship the FT3/rT3 ratio. There is no ideal ratio for someone. SOmeone who has a HIGH rT3 has a problem but there is too much fixation with blood test numbers. Most people do better with an FT3 near the top of the reference range and without excessively high rT3 - but always symptoms and signs tell you if you are hypothyroid - not blood tests.
Okay - I see your point about the fixation
But I want to underline that I'm not talking about free T3 (fT3) - but total T3 (tT3).
