This is ONLY my personal opinion: Any physician who would order an antibodies test and then RULE OUT MG when it comes back negative knows next to nothing about MG. I personally would never go back to such a doctor unless he or she were the only doctor I could see.

My neuro told me that 10 percent of people with MG are negative on all tests, including the SFEMG. My own diagnosis was based on a very positive response to Mestinon. It literally got me out of a wheelchair and walking again.

If your physician continues to be closed minded, find yourself a better doc.
