Glenntaj, Glenn i know what the results of my small fiber skin punch biopsy mean: the number of small fiber nerves per millimeter for the epidermal layer and the number of small fiber nerves on the sweat gland. What I cannot find is what those numbers mean as to degree of severity of the small fiber neuropathy. For instance 0.07 sounds severe to me when abnormal starts at less than 2.9, but i have not been able to find a source that delineates that. Are you aware of a source i could use to determine degree of severity of the resultant numbers? or is anything under the abnormal considered severe?
