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.
SUDOSCAN 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.
SUDOSCAN provides a quantitative measure of chloride conductance (measured in microsiemens, µS) and its results serve as a biomarker to assess sweat gland function. The test results can be used as indicators for patients at risk of autonomic dysfunction through the measurement of Electrochemical Skin Conductance (ESC).
