OVERVIEW
Accurate Detection of Nerve Damage You Can’t See
If you're experiencing burning pain, tingling, or unexplained sensory symptoms, a skin biopsy can help diagnose small fiber neuropathy, a condition often missed by standard nerve tests. We offer precise, minimally invasive testing to identify nerve fiber damage and guide effective treatment.

What is a Skin Biopsy for Small Fiber Neuropathy?
A skin biopsy is a simple, in-office procedure where a small sample of skin is taken, usually from the leg, to evaluate the density of small nerve fibers under a microscope.
This test specifically detects damage to small sensory nerve fibers, which are not assessed by standard tests like EMG or nerve conduction studies.
Symptoms
When You May Need a Skin Biopsy
This test is recommended when patients have symptoms of neuropathy but normal results on EMG or nerve conduction studies.
Common symptoms include:
- Burning or sharp nerve pain
- Tingling or numbness
- Sensitivity to touch
- Unexplained discomfort in the feet or hands
Conditions diagnosed
Small Fiber Neuropathy
Diabetic Neuropathy
Idiopathic Neuropathy
Autoimmune-related neuropathies
Neuropathy related to metabolic or toxic causes

How to prepare for the test
Take a shower before the test. Do not put any lotion, baby oil or cream on your skin.
If you take any medication for pain do not stop them.
If you take any blood thinner inform the neurologist for instructions if you need to hold them

How the test works
A small area of skin is numbed with a local anesthetic. A tiny sample is then taken using a specialized tool. The sample is sent to a laboratory where nerve fiber density is analyzed.
The procedure is quick and typically completed within minutes.

What to expect
Patients can expect minimal discomfort. After the procedure, the area may be slightly sore, but normal activities can usually be resumed the same day.
Basic care instructions are provided to ensure proper healing.

Why is this test important?
Small fiber neuropathy can be difficult to diagnose without specialized testing. A skin biopsy helps:
- Confirm nerve damage that other tests may miss
- Provide objective evidence for diagnosis
- Guide appropriate treatment
