SUDOSCAN (Autonomic and Small Fiber Function Assessment)
SUDOSCAN is a non‑invasive diagnostic device used to assess autonomic nervous system function by measuring electrochemical skin conductance (ESC), which reflects sudomotor (sweat gland) activity mediated by small nerve fibers. The test involves placing the hands and feet on electrodes and applying a low‑voltage electrical stimulus; the device quantifies chloride ion flow as a surrogate marker of small fiber and autonomic integrity in peripheral nerves. At CRC, SUDOSCAN is used to screen for diabetic peripheral neuropathy (DPN), cardiac autonomic neuropathy (CAN), and other forms of autonomic dysfunction, allowing early detection and monitoring of neuropathic progression. It can support risk stratification and tracking in metabolic, endocrine, and neurodegenerative conditions where autonomic dysfunction is common.
