I think what you want to know, Rina, is if small fiber pn can be the same as CIDP.

I googled on the two phrases, which would be the way to find out, and nothing definitive came up right away, but if you've got time, that's how I'd look for that answer.

I think Glenntaj might know for sure, and there's a CIDP board on neurotalk, I believe.

I'm not exactly sure. I know that most people got that diagnosis because they had elevated protein in their spinal fluid on spinal tap, and that that's one reason the test is important.

Good luck,
