I managed to persuade my GP to refer me to an endo, who did TF tests. The results, TSH 0.37 (range .3 to 5.5), Free T3 4.4(Range 0.0 to 7.0), Free T4 17.1 (range 11.5 to 22.7). My GP has called them all normal and is not intending to change my dose - 75 mls levo. I am really perplexed about the ranges for the free T3. How can zero be 'normal'. Does that mean if I have zero free T3, it is OK? I think my free T3 is low and intend to discuss this with the endo when I see him in Feb. Any comments would be appreciated.
