Nerve conduction velocity (NCV), also called electroneurography or nerve conduction study, is a test used to measure the speed of conduction of electrical impulse through a nerve. It is done to diagnose nerve damage and destruction. NCV can be used to diagnose conditions like herniated disk disease, sciatica, peripheral neuropathy, carpal tunnel syndrome, and Guillian-Barre syndrome.
