Polyradiculopathy (can occur with diffuse neuropathy)
* Neurological function tests are abnormal, but no neurological symptoms or clinically detectable neurological deficits indicative of a diffuse or focal neuropathy are present. Class I "Subclinical neuropathy" is further subdivided into Class Ia if an AFT or QST abnormality is present, Class Ib if EDX or AFT and QST abnormalities are present, and Class Ic if an EDX and either AFT or QST abnormalities or both are present.
