Quantitative sudomotor axon reflex testing (QSART)

Also known as: QSART
The quantitative sudomotor axon reflex test measures the amount of sweat that is produced near a nerve.  The sweat glands are stimulated by the application of a small amount of electrical stimulation on the skin.  You may be asked to have this test if your doctor needs additional information to diagnose you with a peripheral nerve disorder. Providence Peripheral Nerve Services┬áprovides patients access to expert clinical evaluations and treatments of neuromuscular diseases. This is carried out by a select group of dedicated physicians specialty-trained in the care of neuromuscular diseases.
