A nerve biopsy is performed to detect nerve-damaging conditions, including leprosy, necrotizing vasculitis (an inflammation of the blood vessels), other nerve inflammation, and damage or loss of the nerve's protective myelin sheath.

A nerve biopsy (removal of a small piece of the nerve) may be performed to look for changes characteristic of CMT. However, this testing is not diagnostic of CMT and is usually not necessary for making a diagnosis.

It is a medical test in which a small portion of a damaged nerve is surgically removed and examined under a microscope

Nerve biopsies are performed in the more serious conditions. The biopsy will permit the physician to see the actual condition of the nerve and rule out other causes for the pain the patient experiences.
