    I have low TSH with normal t4. T3 is very high. I ask my endo about possible t3 toxicosis and possibly using methimizole and levothyroxine. Here is the response. I just wanted to get your thoughts Elaine.

    “We treat T3 toxicosis just like with any other hyperthyroidism and use methimazole - combination therapy with methimazole and levothyroxine is not recommended by the Endocrine society

    There are other situational reasons your T3 was high”

    Hi,
    The problem is that MMI can cause FT4 to fall too low and we have 10-20 times as much FT4 as FT3. I'd ask your doctor to run an FT3 by dialysis to make sure FT3 isn't falsely elevated by other proteins. There may be a problem with some of the testing kits. For instance, I have a 7.8 FT3 but no symptoms of hyperthyroidism. If he won't do a dialysis perhaps he can have your FT3 tested by another laboratory.
    If he's running T3 the test can be falsely high with red stoppered tubes. He could instead order an FT3.
    Best, Elaine
