Hi ,Thanks for the method I had worked it out but you confirmed it for me. I don't know whether my wife should go on the T3 only treatment until she gets further advice re the Pituitary/hypothalamus problemIanFrom: Galathea <galathea@...>thyroid treatment Sent: Sat, 26 March, 2011

Hi,

If you divide the free t3 by the reverse t3, you get 11..... could be a reverse t3 problem? Ideally the ratio needs to be more than 20.

The reverse t3 would push up the free t3 number, so the ratio of Ft4/Ft3 would be high.....
