Another thought. My sister went to one of the nations "leading experts" on MG and told her that her "snarl" and sagging face on one side had nothing to do with MG. He told her that even though she had positive modulating antibodies she did not have MG because her single fiber test was not conclusive. Even though in his book he states that a Neg single fiber test does not mean you don't have MG. So this leading expert says one thing and prints another.
