Direct measurement
Measure your autonomic nervous system
A wearable-based session that independently measures sympathetic and parasympathetic function, revealing regulation that blood tests and imaging do not show.
Most clinics infer autonomic involvement. We measure it.
Standard labs look for structural problems. The ANS Test measures regulation directly, down to each branch, quantifying three things even when standard labs are normal:
Baseline parasympathetic & sympathetic tone and balance
Where each branch sits at rest, and how the two balance.
Autonomic dynamicity and autonomic resistance
How the system shifts under challenge, and the blunted or paradoxical responses that mark dysfunction.
Parasympathetic regulatory function and autonomic responses
How strongly rest-and-digest can engage, and how the system responds.
Together these turn “probably autonomic” into a measurable profile you can target and re-test over time.
Branch-level spectral separation
A pattern standard labs never see
The test runs a six-phase challenge, baseline, deep breathing, recovery, Valsalva, recovery, and standing, and shows how each branch responds at every step.
Why you can trust it
The clinical standard, brought home
The ANS Test runs the autonomic challenge protocol used in clinics since 2006, under a device first FDA-cleared in 1995. That clinical reference device has been used with more than one million patients over two decades. Our measurement is modeled on it, our CAJAL model is trained on an exclusive dataset built with it, and our CMO led the clinical efficacy work behind it before its 2006 launch.
Our at-home delivery is not itself FDA-cleared, is not a medical device, and does not diagnose. Clinical decisions remain with your clinician.
Defined by symptoms, not labels
For people whose tests look normal
- Fatigue despite normal sleep and labs
- Dizziness or racing heart on standing
- Exercise intolerance and post-exertional malaise
- Digestive issues without a structural cause
- Temperature dysregulation
- Anxiety with strong physical sensations
Three steps to objective insight
Open the app
Patients take the test on the Autonomic Health Connect app, or inside the customer’s own app where it is embedded via the SDK. Same experience either way.
Connect your device
Securely connect a compatible wearable (e.g., Garmin, WHOOP, Polar).
Complete the session and get results
Perform the 12-minute autonomic challenge protocol and receive a clear autonomic profile with trend tracking.
CloudANS™ works with data from any compatible consumer wearable and applies Autonomic Health’s proprietary respiratory-independent ANS algorithm. CloudANS™ and the at-home session are not FDA-cleared.
For clinicians
Order the ANS Test for patients who need more information, and track their autonomic regulation over time.
