A Bilateral NCV test is a diagnostic procedure that measures the speed and strength of electrical signals traveling through the nerves in both sides (right and left) of the body. This test helps evaluate the function of peripheral nerves and detect any nerve damage, compression, or neuropathy. During the procedure, small electrodes are placed on the skin over the nerves, and mild electrical impulses are applied. The test records how quickly the nerves transmit signals, allowing the doctor to compare the function of nerves on both sides of the body.
