Thermoregulatory Sweat Test

Show Summary Details


The TST assesses the integrity of central and peripheral efferent sympathetic sudomotor neural pathways. A controlled heat and humidity stimulus is given to produce a generalized sweating response in all skin areas capable of sweating. Sweating is visualized by placing an indicator powder on the skin beforehand. The entire anterior body surface can be examined and abnormalities can usually be detected at a glance.
