Thanks mrsD & glenntaj! And you're so right, dejavu! These folks are the best!

That link is pretty overwhelming, glenntaj, but I see what you mean about the connection to neuropathy, so I can see how his testing for it made sense. I feel like this guy is actually interested and trying, which is new and different! Not just "too bad for you, nothing more to see here, thanks for playing!"

I also had some bloodwork from my primary doc recently that showed low protein and globulin...just wondering because those are two words that are popping up here. (but I'm guessing high would be more consistent?) Maybe not connected...I tend to oversimplify things I don't understand.
