Test Overview
Test Usage

Nerve biopsy is performed to identify primary diseases of the nerve (neuropathies), inflammatory conditions of the nerve, vasculitis, hereditary or storage disorders, etc. Peripheral nerve biopsies are processed for light microscopy with special stains, plastic embedding/electron microscopy (EM) and fiber teasing when needed. The evaluation requires both specific surgical technique and unique handling that differs from routine tissue submitted for pathology evaluation.
