Autonomic Testing Test
Autonomic testing checks if your autonomic nervous system (ANS) is working properly. The ANS controls automatic body functions like breathing, heartbeat, body temperature, and digestion. If results are not normal, it may mean you have autonomic neuropathy, which can affect your heart rate, blood pressure, digestion, bladder, sex organs, sweat glands, eyes, and blood glucose.
What this test measures
Autonomic testing helps find out if your autonomic nervous system (ANS) is working as well as it should. It can show which part of your ANS is affected and how seriously.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
