Melody,
I'm hoping Glenn will jump in on this one. But as I understand it, a sural nerve biopsy will show whether or not Alan has CIDP. Here is a link: http://www.neuro.wustl.edu/NEUROMUSC...her/bx.html#dx Please anyone jump in and tell me if I'm reading this wrong.

But, whether or not he has it, I'd still not want to chance it, because finding out in this manner or not, would not change the treatment of it.
