Private Autonomic Testing in Sydney
Comprehensive same-session testing for POTS, dysautonomia, small fibre neuropathy and orthostatic hypotension. Expert specialist team. Results within one week.
Symptoms We Investigate
If you have any of the following symptoms and your initial workup has not given clear answers, autonomic testing can help.
Conditions We Assess
Autonomic dysfunction can present in many ways. The most common reasons people are referred to us:
POTS
Postural Tachycardia Syndrome — the most common form of dysautonomia we assess. Quantitative testing supports the diagnosis and helps guide treatment.
All conditions →Small Fibre Neuropathy
Burning feet, autonomic features, or unexplained pain. Autonomic testing detects autonomic-fibre involvement; skin biopsy remains the gold standard.
SFN deep-dive →Orthostatic Hypotension
A sustained drop in blood pressure on standing causing dizziness or weakness. The autonomic protocol characterises the underlying mechanism — orthostatic hypotension or autonomic failure.
All conditions →How Testing Works
Everything is done in one visit, usually 40 to 60 minutes. Five complementary tests are performed and interpreted together by your specialist.
Active stand test
Continuous non-invasive blood pressure and heart rate recorded supine, during active standing, and on return to lying (recovery blood pressure), characterising orthostatic intolerance, POTS, and autonomic failure patterns.
Heart rate variability & sympathetic tests
Paced-breathing HRV, the Valsalva manoeuvre, and the isometric handgrip test assess parasympathetic (vagal) and sympathetic adrenergic responses.
SudoScan
Quantifies sudomotor (small-fibre) function rapidly and reproducibly. Useful in suspected small fibre neuropathy and diabetic autonomic neuropathy.

Your Specialist Team
Autonomic testing is interpreted best by clinicians who do it every week. Our team brings together neurology and cardiology — the two disciplines most relevant to autonomic disease.

Frequently Asked Questions
Do I need a referral?
No — a referral is not required for autonomic testing. Your GP's details are helpful, though, so we can send a copy of your report to your doctor. Contact us and we'll arrange an appointment.
How long does the testing session take?
The full session takes about 40 to 60 minutes. All five tests are performed in one visit — no separate appointments needed.
When will I get my results?
Within one week. Your specialist analyses the recordings and issues a detailed report to your referring doctor, with a copy available to you on request.
How are fees handled, and is there a Medicare rebate?
Autonomic function testing is a private service and does not attract a Medicare rebate — none is available for this testing. A fee estimate is provided when you book.
What should I bring to my appointment?
Any recent relevant test results and a list of current medications; your GP's details are helpful so we can send the report. Avoid caffeine, nicotine and heavy meals for at least four hours before the appointment as these can affect the recordings.

Autonomic Function Testing for Your Patients
Quantitative same-session autonomic protocol with rapid turnaround. Specialist neurologist and cardiologist team. Detailed reporting suitable for diagnostic workup, medicolegal documentation, and treatment planning.
When to Refer
The patients most likely to benefit from quantitative autonomic testing.
Suspected POTS
Symptomatic orthostatic intolerance with disproportionate tachycardia on standing. Testing supports the diagnosis and excludes orthostatic hypotension or autonomic failure.
Orthostatic hypotension
Sustained orthostatic blood-pressure fall, with or without a negative cardiology workup. The active stand protocol characterises orthostatic hypotension and autonomic-failure mechanisms.
Suspected SFN
Burning feet, autonomic features, or unexplained distal pain. SudoScan plus full autonomic protocol identifies autonomic-fibre involvement to support skin-biopsy decision-making.
Diabetic / chemotherapy autonomic neuropathy
Quantification of cardiovascular and sudomotor autonomic involvement. Useful for baseline characterisation and progression monitoring.
Post-viral / long-COVID dysautonomia
Quantifies the autonomic component when symptoms suggest POTS-like physiology or orthostatic intolerance following viral illness.
Suspected synucleinopathy
Early or atypical Parkinsonian or MSA presentations. Autonomic failure on testing supports the differential and informs prognosis.
The Testing Protocol
Five complementary tests performed in a single visit (usually 40–60 minutes), interpreted together. Domains covered: cardiovagal, adrenergic, sudomotor.
Active stand test with recovery BP
Continuous non-invasive blood pressure plus heart rate recorded supine, during active standing, and on return to lying (recovery BP). Distinguishes POTS, orthostatic hypotension, and autonomic failure patterns. Quantifies the orthostatic response against normative ranges.
Paced-breathing HRV
Cardiovagal function assessed via heart-rate response to controlled deep breathing. Reduced E:I ratio supports parasympathetic dysfunction.
Valsalva manoeuvre
Combined assessment of adrenergic (BP recovery, late phase II), cardiovagal (Valsalva ratio), and baroreflex sensitivity. Pattern recognition identifies the specific limb affected.
Isometric handgrip test
Sustained handgrip drives a reflex blood-pressure rise; the magnitude quantifies efferent sympathetic adrenergic function. A blunted response indicates adrenergic failure.
SudoScan
Sudomotor function quantification via electrochemical skin conductance. Detects small-fibre autonomic involvement; sensitive in early diabetic autonomic neuropathy and SFN.
Contraindications to flag at referral: implanted electronic devices (pacemakers, ICDs, neurostimulators), pregnancy, or unstable cardiovascular status — SudoScan is omitted and the active stand and handgrip portions modified.

Referral Logistics
What to send, what to expect, and how the report comes back.
How to send
Standard specialist referral by fax, email or e-referral to Dr Ron Granot (Neurology) or Dr Jason Kaplan (Cardiology) at Autonomics Australia / East Neurology.
Turnaround
Urgent patients typically seen within 1–2 weeks. Report issued within one week of the testing session. Substantially faster than 6–12 month public-system waitlists.
What the report contains
Quantitative results for each test with normative ranges, integrated clinical interpretation, and a summary of autonomic domains affected.
Clinical FAQ
Which patients benefit most from autonomic function testing?
Suspected POTS, orthostatic hypotension (especially after a negative cardiology workup), suspected small fibre neuropathy with autonomic features, diabetic or chemotherapy-related autonomic neuropathy, post-viral or long-COVID dysautonomia, autoimmune autonomic ganglionopathy, and patients with suspected synucleinopathy where autonomic involvement may support the diagnosis.
What does the report contain?
A detailed quantitative report covering each of the five tests with measured values and normative ranges, clinical interpretation integrated with the history, a summary of autonomic domains affected (sympathetic / parasympathetic / sudomotor). The report is suitable for use in subspecialty workup, medicolegal documentation, and treatment planning.
How quickly can a patient be seen and reported?
Urgent patients are typically accommodated within 1–2 weeks. Reports are issued within a week of testing — substantially faster than the 6–12 month waitlists common at public autonomic units.
How do I refer?
Send a standard specialist referral to Dr Ron Granot (Neurology) or Dr Jason Kaplan (Cardiology) at East Neurology / Autonomics Australia. Fax, email or e-referral accepted. A brief clinical summary and relevant prior investigations help us triage appropriately.
