Gad25 ab & Ganglioside Asialo gm1 igG ab - both high?

I am in the middle of being tested for stuff, and most of my searches of various things the last several months brings up MS as a possibility. Several other things have come up, but I don't quite fit any of them.

My neuro wants to do an EMG

I know, I sound ridiculous, but I have been right in the past about a number of health-related things. I have been correct in the diagnoses for my children, too. Anyway, my neuro wants an EMG sooner than the one scheduled in July, and I have heard nothing. I keep messaged them because they told me to, but if not by tomorrow, I must call myself.

MRIs with and without contrast

MRIs with and without contrast will happen in six days (which is just peachy - I feel like the blood is rushing to my head without a pillow on the MRI machine. Although I feel like that in bed as well if I am not at an exact angle).

My GAD25 ab came back rather high

Anyway, I had some bloodwork drawn because my neuro wanted to check for stiff-person syndrome. My GAD25 ab came back rather high, as did my ganglioside Asialo Gm1 IgG antibodies. I want to argue with the SPS idea, due to my reading about it as I don't quite have all the symptoms. And I am having trouble finding solid info about these two things having anything to do with each other.

Could this indicate MS?

My sedimentation rate is just slightly high, but I don't know if that has anything to do with anything else. I know GAD25 has to do with the possibility of some encephalomyelitis form, and from what I understand, MS is one them. However, I look up GAD25, and I only really see journal articles and things that have to do with SPS or Diabetes Type 1 (adult-onset). I don't believe I have Diabetes because apparently the GAD number is too high, but I could be wrong. I am very confused and not very patient because of my symptoms that have been going on for months (probably years, but I won't get into all of that here.) I hope I not completely off here. Thanks.
