You are welcome.
Testing four times a year! That is a lot. I see the benefit, but how can anyone afford it? That test is so expensive, it was either $600 or $900, I can't remember now. If his symptoms are severe, he should stay even if the antibodies aren't high, that makes sense, best to be safe. MG is so unpredictable.
Please be sure to tell your doctor about the tea before drinking it, just to be on the safe side.
