In particular, you should get an immunofixation electrophoresis of serum and urine to check for rogue polycolonal and monoclonal proteins and cryoglobulins, which are associated with neuropathy through antibody cross reaction to nerve antigens. Moreover, there are now assays for antibodies specific to components of peripheral nerve that were not available 19 years ago. And an overall physical exam would probably be a good idea to eliminate something new.
