SudoCheck Sudomotor testing device has been created to enable a precise evaluation of sweat gland function. It is based on a measuring method, whereas patients place their hands and feet on stainless-steel electrodes and are exposed to an incremental low direct voltage - lower than 4 V - that is released in intervals of two minutes. What is being tested is the electrochemical reaction between electrodes and chloride of the, through low voltage stimulated sweat glands. This active, new method provides information and evidence of a sweat dysfunction that might otherwise not be detectable in physiological conditions. Bioelectrical Conductances (BEC, in microsiemens, uS) for the hands and feet, express the quantitative results, while a risk score is derived from demographic data and the BEC values.
