A nerve biopsy is the removal of a small piece of a nerve for examination.
Alternative Names:
Biopsy - nerve
How the test is performed:
The sural nerve (in the ankle), or the superficial radial nerve (wrist) are the sites most often used for biopsy. A local anesthetic is used to numb the area. A small incision is made, and a portion of the nerve is removed. The sample is then examined using either a regular (light) microscopic or an electron microscope. Individual nerve fibers may also be examined.
How to prepare for the test:
There is no special preparation.
Infants and children:
The preparation you can provide for this test depends on your child's age and experience. For general information regarding how you can prepare your child, see the following topics:
The amount of pain during and after the procedure depends on the patient. Because a local anesthetic is used, discomfort during the procedure is usually minimal. The anesthetic may burn or sting when first injected. After the procedure, the area may feel tender or sore for a few days.
