SUDOSCAN principle

A test of sudoral function

The degeneration of small nerve fibers reduces sweat gland innervation and impairs sudomotor function.

SUDOSCAN tests sweat gland function by applying a small direct current to both hand and foot sensor plates. At a low voltage, the stratum corneum acts as a capacitor, leaving the sweat ducts as the only channel for the transmission of Cl- ions.

SUDOSCAN provides a quantitative measure of chloride conductance (measured in microsiemens) and its results serve as a biomarker to assess sweat gland function in relation to sweat gland innervation.

Easy to read results

The polarity of the stainless steel sensor plates is swapped during a scan to record individual right and left side conductance values. Patient results are displayed right after the end of the scan. The amount of observed asymmetry is an indicator of the type of peripheral neuropathy.
The physician can also display the follow-up over time curve of several SUDOSCAN scans.
