The autonomic nervous system (ANS) controls involuntary, physiological actions such as blood pressure, heart rate, metabolism, digestion, and more. When damaged or altered by a disorder, the ANS may produce a number of symptoms like heat intolerance, nausea, constipation, and urinary retention or incontinence. To determine whether or not the physiologic responses of the ANS have been compromised, a TriState Pain Institute physician may administer a series of tests to evaluate the system's level of functioning.
The quantitative sudomotor axon reflex test [QSART], thermoregulatory sweat test [TST], and silastic sweat imprint test are just a few diagnostic tools used during the ANS screening at TriState Pain Institute. Depending on your health history, current health status, and symptoms, you may be required to undergo additional testing.
Purpose of ANS Screening
ANS screening may be deemed medically necessary for patients showing symptoms of vasomotor instability. This is common in patients with different types of neuropathy such as:
Pure autonomic failure
Multiple system dystrophy
Although ANS screening helps identify dysfunctions of the nervous system, it is not a test capable of diagnosing a specific disease. Talk to a TriState Pain Institute physician about ANS screening for signs of disturbances within the autonomic nervous system.
