Cutaneous Nerve Laboratory

The Cutaneous Nerve Laboratory is a CAP approved, clinical diagnostic lab that specializes in the evaluation of small fiber sensory neuropathy through simple skin punch biopsies.

What is Small Fiber Sensory Neuropathy?

Small fiber neuropathy (SFN), or peripheral sensory neuropathy, affects small caliber nerve fibers. Patients who have this disease most often experience tingling, burning, or numbness in the arms, legs, or feet.

Patients may also experience sensitivity to temperature (heat or cold) and/or automatic dysfunction.

Causes of SFN

Common causes of SFN include: diabetes, HIV, alcohol or drug abuse, and use of neurotoxic agents. Often, the cause of SFN is unknown.
