Know More



SUDOSCAN is a test that provides an accurate evaluation of sweat gland function.

SUDOSCAN’s focus 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: > Diabetes > Parkinson > Chemotherapy induced polyneuropathy > Familial amyloid polyneuropathy > Fabry disease


Impeto Medical has developed a patented technology that assesses sudomotor function through sweat gland activity. It is non-invasive and analyses the ability of sweat glands to release chloride ions in response to an electrochemical stimulus. Sweat conductances are then measured on the palms of the hands and the soles of the feet. The level of sweat gland activity is linked to the status of small nerve fibers innervating sweat glands. Small nerve neuropathy can be present in the early stages of diabetes and prediabetes.

Based on this technology, Impeto Medical has developed :

  • SUDOSCAN, a medical device for the early detection and follow-up of Peripheral Autonomic Neuropathies.
