NCV Test (Nerve Condition Velocity) is the most common type of test that measures the speed of electrical impulses moving through the nerves. NCV test happens to be the marker for potential nerve damage.
During this test, the nerve would be stimulated with the help of patches of electrodes attached to the skin. Using two electrodes would be placed on the skin over the nerve. While one electrode would stimulate the nerve with a gentle electrical impulse, the other electrode would record it. The process is repeated for one nerve at a time that needs to be tested.
Thereafter, the speed would be calculated by calculating the distance between the electrodes and the time is taken for electrical impulse travelling between electrodes.
Related tests like EEG scan, EMG test, VEP test, and SSEP test may be done to measure different markers. These tests determine the location, presence, and extent of nerve disease that damages the muscles too.
NCV test can be done in BR Diagnostics Delhi at some of the top centres for neurological tests. Before going for the test, it is better to know about NCV test price along with EEG test price, and EMG test cost, as these tests are done together.
When Is It Necessary To Do NCV Test?
NCV test is usually done together with the EMG test to determine the difference between muscle disorder and nerve (neurological) disorder. NCV helps detect the problematic nerve, while the EMG test detects whether the muscles are working efficiently in response to the stimulus of the nerve.
NCV test helps detect the following conditions or diseases:
- Guillain-Barre Syndrome.
- Charcot-Marie-Tooth Disease.
- Carpal Tunnel Syndrome.
- Chronic Inflammatory Polyneuropathy and Neuropathy.
- Herniated Disk Diseases.
- Sciatic Nerve Disorders.
