Austin Neuromuscular Center offers on-site muscle, nerve, and skin biopsy procedures along with pathology services in our CAP (College of American Pathologists) and CLIA (Clinical Laboratory Improvement Amendments) certified lab. We perform all biopsy procedures on-site and use local anesthesia to ensure that you are kept comfortable.

Muscle and nerve biopsies are indicated for a variety of muscle and nerve diseases, such as myositis, metabolic myopathy, hereditary myopathy, and vasculitis. The site of the tissue sample will depend on where you are feeling pain or weakness. Most often, samples are taken from the upper arm and thigh. For further details, please review our muscle biopsy information packet.

Skin biopsies are a minimally invasive procedure that we use to diagnose small fiber neuropathy. Skin biopsies are helpful in evaluating small sensory nerve fibers that are harder to capture with an EMG/nerve conduction study. Generally, skin biopsies are done at the ankle and thigh, and they are 3 millimeters in diameter and 2 millimeters deep. The procedure typically takes around 10 to 15 minutes. To learn more, you may read our skin biopsy information packet.

Tissue samples are frozen and stained with different reagents for histochemical studies. Dr. Hussain interprets the results, and we then send the report to the referring provider within 2 to 3 weeks. Remaining frozen tissues will be saved for potential future studies, such as electromicroscopic studies.

After we perform a biopsy, we will give you instructions for post-procedure care to ensure a smooth, quick healing process.
