Just got tested and I have a free t4 of 1.6 (0.8-1.8) a total t4 of 13.9 (4.9-10.5) and a tsh of 0.4 (0.4-4.5). My tsh is usually 3-5 and trends in the 5’s.
What would cause this to occur? I have hashis and am on 100 mcg synthroid one day and 88 mcg the next, alternating.
I know I am missing free t3.
