A nerve conduction test (NCV) is a diagnostic testing method used to assess the extent of your nerve damage. You may be asked to take the NCV test when there is suspicion of nerve damage caused by neuropathy. Nerve conduction testing is vital because many nerve pain conditions are irreversible, especially serious cases of diabetic neuropathy. https://www.neuroinjuryspecialists.com/diagnostic-testing/nerve-conduction-test-ncv/
