Well, because when you contract a muscle, it can give a false positive or a false negative. I find it completely interesting that they are so 100% sure of how they are doing a test and then backtrack and say it may not give them the best results.

When they do a muscle biopsy, they can actually stimulate that muscle to see what happens. In essence, this is the same thing without the biopsy.

This is off this topic but I had to comment on it. Whose to say that MG affects ALL 640 skeletal muscles equally? Lupus doesn't cause inflammation in some kind of obvious, same old/same old pattern in everyone. Even breast cancer has different "species" that affect people differently.

You know how doctors like things in an easy algorithm. Your particular MG, I believe, is simply a unique variation on a theme.
