SUDOSCAN: Early Identification of Peripheral Autonomic Neuropathies
SUDOSCAN+ is a test that provides an accurate evaluation of sweat gland function focusing on small nerve fibers within the peripheral nervous system innervating the sweat glands. SUDOSCAN+ measures the ability of the sweat glands to release chloride ions in response to an electrochemical stimulus on the palms of the hands and soles of the feet, areas with the highest sweat gland density. SUDOSCAN+ test results can be used as indicators for patients at risk of autonomic dysfunction through the measurement of Electrochemical Sweat Conductance (ESC) and the amount of observed asymmetry between the right and left side. SUDOSCAN+ has been tested for small fiber nerve neuropathies in several diseases and compared to guidelines reference tests: for Diabetes, Parkinson, Chemotherapy induced polyneuropathy, Familial amyloid polyneuropathy. It is also being used to diagnose diabetes in other countries.
