The article talks about the guidelines and says:

..............The guidelines recommend that doctors obtain certain blood tests for all patients with numb, painful feet. "People with suspected nerve problems should talk to their doctors about screening tests, especially blood glucose, vitamin B12 level and serum protein levels, since these tests can often point to common causes of neuropathy," said England.
The guidelines recommend tailored genetic testing for accurately diagnosing certain neuropathies that run in families.
The guidelines further recommend that doctors consider a combination of specialized tests to accurately evaluate neuropathies with autonomic dysfunction. These tests, known as autonomic tests, measure the action of the tiny nerves that control such functions as sweating, heart rate and blood pressure. Skin biopsy may also be useful to diagnose loss of tiny nerve fibers in the skin.
The guidelines were developed in full collaboration with the American Association of Neuromuscular and Electrodiagnostic Medicine and the American Academy of Physical Medicine and Rehabilitation.


But it doesn't't have a link to the full guidelines themselves, or suggest where to go to get them.

Dahlek's link to the interview article with the author is more revealing
but still doean't say where to go to see the actual guidelines.

Am I missing something?
