My bloodwork is normal with the exception of RNP antibodies, which the neuro thinks is due to MG. The diagnosis was due to symptoms, repetitive nerve stim, and single fiber EMG. I had some more blood work a couple of days ago and will find out the results in 2 weeks. Everyone, including the EMG technicians, knows about my neck issues. I only found out about the discs because my neuro sent me for an MRI. Really, I don't know for certain that I have MG yet and won't feel secure in the diagnosis until the results of the final tests come in but my neuro feels "98% certain" of the diagnosis.
