A SudoScan is a test that provides an accurate evaluation of sweat gland function. The test focuses on small nerve fibers that innervate the sweat glands. The degeneration of small nerve fibers reduces sweat gland innervation and impairs sudomotor function.  Measures the ability of the sweat glands to release chloride ions in response to an electrical stimulus on the palms of the hands and soles of the feet, areas with the highest sweat gland density.
