How much a neuromyography test costs depends on its specific items. This test includes several items such as nerve conduction velocity, electromyography, brainstem auditory evoked potentials, somatosensory evoked potentials, visual evoked potentials, and repetitive electrical stimulation. For the simplest nerve conduction velocity and electromyography, it is$20 for one nerve, and the specific charge is determined by how many nerves and how many sites the patient needs to have done. For example, for nerve conduction velocity of the extremities, the charge is between 200-300 RMB, and if EMG of the extremities is added, the charge is between 500-600 RMB. Evoked potentials include auditory somatosensory of the brainstem, as well as visual evoked potentials, for a total fee of about$500. Repetitive electrical stimulation tests used to detect neuromuscular junction disorders are charged at around$200-300.
