You often read that FT4 and FT3 should be in the upper third or 50% in range. How do you calculate where your level is right now?
I understand it's different for everybody, what a good level is for me could be hyper for someone else.
But like FT3, some say it has to be in the upper 75%. When I calculate that with the ranges of my lab someone said that is way too high and would be considered hyper.
So, how do you calculate at which percentage your results are now and what is the goal?
