Muscle and Nerve Biopsy

About Our Service

Usually completed on an outpatient basis, a muscle biopsy is a procedure used to identify an infection or disease in your muscle. During the procedure, we use a needle to remove a tiny bit of tissue for testing. You can have local anesthesia or doctors are able to numb the area being tested; so you’re awake but can’t feel the area being examined. 

There are a variety of reasons your doctor may request you have a muscle biopsy, including to determine if your symptoms are related to a muscle condition or a concern with your nerves, such as if they feel your nerves are damaged or you’re experiencing symptoms similar to neuropathy, inflammatory disease of the nerve or various other nerve and muscle conditions. 

After the test, your doctor typically gets results within one or two weeks.
