Peripheral autonomous nervous system testing
QSART/Sudoscan testing available at NeiroMed clinic!
An innovative and accurate examination that allows early diagnosis of autonomous and fine fibre neuropathies, including in patients with diabetes mellitus, parkinsonism, autoimmune diseases, etc.
The Quantitative Sudomotor Axon Reflex test (QSART), or SUDOSCAN test, allows you to assess the function of autonomous nerve fibres by measuring the reaction of sweat glands to a tiny electrochemical stimulus. Sweat conductivity (ESC) is analysed in the hands and feet – areas with the highest density of sweat glands.
Why do this test?
- Early diagnosis of autonomic neuropathy and fine fibre polyneuropathy
- Fast, accurate, non-invasive and painless method
- Suitable for patients with chronic diseases and autonomous symptoms
- Results are evaluated by a neurologist with experience in diagnosing neuropathy
- Available without queues, at out-patient clinic, on previous booking
How is the examination going?
- When you arrive at the clinic, you will be asked to remove your shoes and socks.
- You’ll stand on sensor plates with feet, you’ll place your hands on hand sensors.
- You won’t feel pain during the examination – just a mild electrical impulse while measuring the conductivity of the sweat glands.
- Test duration: approximately 3-5 minutes.
Duration of examination
Up to 15 minutes
Preparation
Please follow some simple suggestions: Do not use creams, lotions or ointments on your hands and feet on the day of the exam. Let your doctor know about any medication you are taking.
Feelings
The test is completely painless and non-invasive
Restrictions
None
Results
Results are available within 3 days of the exam. They shall be analysed and interpreted by a certified physician who shall provide conclusions and, if necessary, recommendations for further treatment. THE QSART test can also serve as an objective indicator for assessing treatment effectiveness
When is this test recommended?
The QSART/Sudoscan test is useful when autonomous neuropathy or fine fibre damage is suspected, including in the following cases:
- Diabetes mellitus (with or without symptoms)
- Parkinson’s disease and other neurodegenerative diseases
- Chemotherapy induced neuropathy
- Genetic neuropathic syndromes (e.g. Fabry disease, amyloidosis)
- Fibromyalgia
- Sjögren’s syndrome
- Lyme disease
- HIV infection
- Autoimmune diseases
- Evaluation of the efficacy of therapy in neuropathy
Common symptoms suggestive of peripheral autonomic dysfunction
Cardiovascular system:
- Dizziness at posture shift
- Orthostatic hypotension
- Abnormal heart rate
Gastrointestinal tract:
- Abdominal bloating, diarrhoea, constipation
- Nausea after eating
Urogenital system:
- Incontinence or retention
- Sexual impairment
Skin and sweating:
- Perspiration disorder
- Bad heat tolerance
Others:
- Unexplained weight loss
- Pupil reflex disorder
Don't miss the chance to diagnose fine fibre neuropathy in time!
