The only test form me so far to show anything is elevated IgA. At first they thought this might indicate Celiac, but intestinal biopsy was negative.

Now, my neuro is having me do a urine test, to test for Paraprotein Related Neuropathy. It is a test that will show if there is Monoclonal proteins, usually IgM, IgG, or IgA with either kappa or lambda light chains.

I'm anxious to see if this will point out anything for me. I've noticed that some people here have had some paraneoplastic testing done, but I didn't notice if you all had had this kind of test done. It is a immunoelectrophoresis test. Sound familiar to anyone?

Here is a link to a paper that talks about Paraportein Related Neuropathy:
