Who gets an NCV test?

An NCV test can be used to diagnose a number of muscular and neuromuscular disorders, including:

• Guillain-Barre syndrome
• carpal tunnel syndrome
• Charcot-Marie-Tooth (CMT) disease
• herniated disk disease
• chronic inflammatory polyneuropathy and neuropathy
• sciatic nerve problems
• peripheral nerve injury

If your doctor suspects you have a pinched nerve, they may recommend an NCV test.

An electromyography (EMG) test is often performed alongside an NCV test. An EMG test records the electrical signals moving through your muscles. This helps detect the presence, location, and extent of any disease that may damage the nerves and muscles.
