Sudo scan is the accurate medical test that is performed to evaluate the functioning of sweat gland. This non-invasive test can detect the abnormalities in the ionic balance of the sweat. It focuses on the small nerve fibers to get the accurate results.
This medical test evaluates the functionality of sweat gland (to release of chloride ions) by using an electrochemical activation. It is performed on the palms of the hands and soles of the feet, and takes only three minutes to complete.
