If your neurologist is also heavily involved in MS research, he/she is more likely to have access to the labs that will run more of the newer CSF tests. It's definitely something to look into. Also, I know my practice in NYC (MS Research Center of NY and International MS Management Practice) was asking for CSF donations for research purposes. If you're stateside, it might be a free option to get all of these tests done in a really incredible clinic. I'm not positive if they're still doing this CSF program, though...I last checked a few months ago.
I will definitely give you as much information as I can regarding the different tests run on my CSF. I won't get it backfor another two or three weeks, at the earliest, though.
