Clinician-Guided
At-Home Testing
Comprehensive Autonomic Assessments

Clinician-guided, at-home autonomic nervous system testing designed to help healthcare providers evaluate complex patients—without requiring every patient to travel to a specialty testing center.
For many patients with complex or unexplained symptoms, getting an autonomic nervous system assessment can mean traveling long distances, waiting months for a specialty appointment, or navigating the physical and emotional burden of visiting a testing facility.
The enhanced Remote Autonomic Diagnostics-as-a-Service program brings clinician-guided autonomic testing directly to the patient's home.
A portable Physio PS diagnostic kit is shipped to the patient. A trained clinician guides the patient through the testing remotely. The equipment is returned using a prepaid shipping label, and the treating physician receives the resulting test report to support clinical evaluation and care planning.

The Remote Autonomic Diagnostics-as-a-Service model combines the technology of the FDA-cleared Physio PS 4.0 SaMD with remote clinical administration and reporting.
The result is a testing model designed to extend access to autonomic assessment while maintaining clinician involvement throughout the testing process.
The program includes:
Portable diagnostic equipment shipped directly to the patient
Three-lead ECG for cardiac monitoring
Blood-pressure cuff for blood-pressure assessment
Remote clinician guidance throughout the testing process
Guided autonomic testing protocols, including breathing and standing components when appropriate
Prepaid return shipping
Formal test results provided to the treating physician
Physio PS technology is designed to quantitatively assess parasympathetic and sympathetic activity independently and simultaneously.
For decades, access to specialized autonomic testing has often depended on where a patient lives and whether a specialty center is available nearby.
Physio PS is working to change that.
The diagnostic capability can come to the patient—not the other way around.
Remote autonomic testing may be particularly valuable when patients have persistent or unexplained symptoms and access to specialty autonomic testing is limited.

Physio PS's clinical resources identify orthostatic intolerance, syncope, POTS, EDS, post-COVID/Long COVID, exercise intolerance, and nervous-system disorders among areas where autonomic assessment may provide additional information for clinicians.
A self-contained Physio PS diagnostic kit is shipped directly to the patient's home.
The kit includes the equipment required for the remote assessment.
The patient receives remote guidance from a trained clinician who helps with equipment setup and prepares the patient for testing.
The clinician administers the appropriate Physio PS testing protocol remotely.
After testing, the patient repacks the equipment and returns the kit using the included prepaid shipping label.
The treating physician receives the formal test results to support clinical assessment, diagnostic decision-making, and individualized care planning.
Depending on the protocol and clinical circumstances, testing may include:
Rest → Guided Breathing → Standing / Orthostatic Challenge → Recovery
The testing is designed to capture physiological responses rather than relying solely on symptoms reported by the patient.
The value of the program isn't simply moving equipment from a clinic to a patient's home.
Traditional specialty testing can require:
The Remote Autonomic Diagnostics-as-a-Service model creates another pathway:
That can help extend specialized testing to patients who live far from specialty centers or face barriers to traditional testing.
The autonomic nervous system helps regulate many functions that occur automatically—including heart rate, blood pressure, breathing, digestion, temperature regulation, and the body's response to stress.
When autonomic regulation becomes impaired, patients may experience symptoms affecting multiple systems.
The challenge is that these symptoms can be intermittent, nonspecific, and difficult to connect to a single underlying mechanism.
Physio PS is designed to provide clinicians with quantitative information about autonomic function by assessing the parasympathetic and sympathetic branches independently and simultaneously.
Instead of asking only:
"What symptoms is the patient experiencing?"
Clinicians can also ask:
"What is the patient's autonomic system doing?"

Some patients don't fit neatly into a single diagnostic category.
They may see multiple specialists.
They may have normal results on conventional testing.
They may be treated for individual symptoms without a clear picture of the underlying physiology.
And they may continue to struggle.
Remote autonomic assessment can provide another layer of physiological information for the treating clinician.
Potentially relevant patient populations include:
POTS and suspected POTS
Syncope and orthostatic intolerance
Post-COVID and Long COVID
Chronic fatigue
Exercise intolerance
Hypermobility and EDS
Complex chronic pain
Neurological disorders
Cardiovascular conditions
Patients with persistent unexplained symptoms
Physio PS currently positions its technology for use across multiple specialties and clinical conditions, including cardiology, neurology, physical therapy, orthostatic intolerance, syncope, POTS, EDS, and post-COVID conditions.
We're incredibly proud of the positive impact our products have made. Here’s a look at what people are saying, with five-star reviews from satisfied customers.
"Physio PS has been a gamechanger in uncovering the hidden autonomic dysfunctions that often underlie chronic fatigue, persistent pain, anxiety symptoms, and delayed recovery after whiplash and concussion. It’s given us answers when nothing else could — and a clear path to true healing."

"As a VA Electrophysiologist, I’ve used ANSAR’s Parasympathetic and Sympathetic Monitoring for years with outstanding results. It delivers diagnostic insights no other tool can provide. One case—a Navy SEAL suffering from severe dizziness and disability—was accurately diagnosed and effectively treated using ANSAR technology, after traditional tests failed. The patient regained his health, quality of life, and independence. This tool is a game-changer for patient care and healthcare efficiency."

"I cannot say enough good things about Physio PS! This technology has done so much for me. I used to have terrible anxiety storms that would cause me to have high fevers. With this simple test, my doctor was able to find the root cause of my symptoms and prescribe a very low-dose medicine for about nine months to correct the primary problem. I have not had a high fever in four years!"

Physio PS is designed to provide quantitative information about autonomic nervous system function, including assessment of sympathetic and parasympathetic activity independently and simultaneously.
Testing may also capture physiological responses associated with breathing, standing, blood pressure, heart rate, and recovery, depending on the protocol.
The autonomic nervous system has two primary regulatory branches: the sympathetic and parasympathetic systems.
Assessing their activity independently can provide clinicians with additional information about autonomic regulation that may not be apparent from symptoms or conventional measurements alone.
Depending on the patient's clinical circumstances and applicable protocol, testing may include:
Rest → Guided Breathing → Standing/Orthostatic Challenge → Recovery
The testing protocol is determined and administered by the appropriate healthcare professional.
The patient's treating physician or authorized healthcare provider receives the formal test results.
Physio PS does not replace the treating clinician's role in diagnosis, interpretation, or treatment planning.
Physio PS provides physiological information that may assist a qualified healthcare professional in evaluating autonomic function.
The treating healthcare professional is responsible for interpreting the results and determining whether a patient meets diagnostic criteria for POTS, dysautonomia, or another condition.
Physio PS does not independently diagnose or treat patients.
Autonomic dysfunction may be present in some patients experiencing persistent post-COVID symptoms. Remote autonomic testing may provide clinicians with additional physiological information when evaluating patients with post-COVID or Long COVID symptoms.
Once testing is completed, the patient returns the equipment using the prepaid shipping label. The resulting information is processed into a formal report for the treating physician.
The physician can then incorporate the results into the patient's broader clinical evaluation and care plan.
The Physio PS ecosystem can support ongoing monitoring through wearable devices and digital tools, where applicable.
This creates an opportunity for clinicians to evaluate changes in patient information over time rather than relying exclusively on a single assessment.
Human OS is an interpretation and reporting application that enhances the Physio PS remote diagnostic service with AI-enabled capabilities.
