I am getting my records together to send to John Hopkins. One of the tests they asked to forward was a muscle biopsy. I have not had one. How many here have had a muscle biopsy??

In fact, I have not had many test to differentiate from MG. I only had tests to confirm MG. They did do an MRI of the Brain and evoc potential to see if it was MS. They did do and MRI of the spine an emg to rule out herniated disc interferring with the nerve impulses to my LEG. They did do a lot of antibody blood work to rule out other autoimmune diseases - anti- ANA, RA, YO, ANCA, SSA, SSB, SM etc.

Has every one else had a lot of differential test to rule out other disease than MG? If so, what kind.

thanks
