Hello,
I am a new member on the forum. My father was diagnosed with ALS last year, but there are some symptoms which do not comply with the diagnosis. It looks more like MG - for example. double vision, which never happens with ALS patients. The doctors made a blood test to detect some antibodies typical for MG. They did not find too many of them and ruled out MG. I have heard there are other ways to diagnose MG, and sometimes, even though blood test is negative, it is still MG.

Has anybody heard of alternative ways to diagnose MG?
Thank you,
AlexM
