Here's my experience: I tested negative for the antibodies. My first SFEMG came back "borderline." My second one came back "abnormal, but not enough to be conclusive for MG." Then my doctor sent me to an MG specialist in Boston. He did a third SFEMG, this time on my face (even though I don't really have eye symptoms). It came back very abnormal, and he diagnosed me with MG.

What to make of this, I don't really know. Maybe I'm a fluke, or maybe the way SFEMG's are read varies more than we realize. Maybe something was interfering with the readings of the first SFEMGs.
