LizaJane posed a question about Spinal Taps being used for diagnosis of immune type neuropathies...
I replied that that aspect seemed to be the norm, but there's a new article just published that got me to 'google' about biopsies, which are becoming less in favor or use.
Here is one:

The middle paragraph is of interest regarding biopsies and which kind.

Here is the 'list' according to Harvard as of 2002....I think it needs updating and is pretty sparse when compared to LizaJane's sheets:

In addition, this index and the pics are useful in 'understanding' it all to a degree.

This is another article by Fink/Oaklander about the biopsy aspects, tho diagnostic outlines are a bit vague, the pros/cons of QST [which I've not had] are sort of interesting....

I hope these articles are useful to someone, I'm not sure they're in the 'stickies' or not. - j
