Sorry, just realized i had a message ( still learning the ins and outs ). The tests they performed wereNCS)nerve conduction study. (EMG)needle electromyography. An MRI on my spine. Blood test for elevated Anti-GM1 antibodies. Plus all the standard office tests. All this is done to eliminate other diseases. They found 2 conduction blocks during the NCS which generally means (MMN) multifocial motor neuropathy. Hope this helps the person that sent me a message. Thank you Jim
