Autonomic Nervous System Test in Seoul

Hair loss has many possible causes, and stress-related nervous system imbalance is one factor clinicians sometimes evaluate. For patients considering an autonomic nervous system test in Seoul, this page explains what the test measures, who it is meant for, and what to expect during a visit to Hairon Clinic, located on the 3rd floor of the Hongwoo Building, 373 Gangnam-daero, Seocho-gu, Seoul.

What It Is

The Autonomic Nervous System Test, listed in Korean as 자율신경 검사, measures heart rate variability to assess the balance between the sympathetic and parasympathetic branches of the nervous system. This balance is sometimes linked to chronic stress, which can be one of several contributing factors in certain patterns of hair thinning. The test itself is non-invasive and is typically used as part of a broader evaluation rather than as a standalone diagnostic tool for hair loss.

By reviewing autonomic nervous system activity, the examining physician may gain additional context about a patient's overall physiological stress response. This information is generally considered alongside scalp examination, medical history, and other relevant findings when discussing hair loss with a patient.

Who It Suits

This test may be suggested for patients who:

• Report noticeable hair shedding coinciding with periods of high stress, poor sleep, or lifestyle changes
• Have not identified a clear structural or hormonal cause for their hair loss
• Are interested in a broader physiological assessment as part of their consultation
• Wish to explore whether nervous system imbalance may be a contributing factor alongside other causes

Because hair loss is multifactorial, results from this test are typically interpreted as one piece of a larger clinical picture rather than a definitive explanation on their own.

Who Should Avoid It

The test is generally low-risk given its non-invasive nature, but there are situations where results may be less reliable or where a physician may recommend deferring the test, including:

• Patients with certain cardiac arrhythmias or pacemakers, which can affect heart rate variability readings
• Patients who are acutely anxious or physically agitated at the time of testing, since this can skew results
• Patients who have recently consumed caffeine, alcohol, or stimulant medication shortly before the appointment

Patients with existing cardiac or neurological conditions should mention this during consultation so the physician can determine whether the test is appropriate and how to interpret findings in context.

How the Session Goes

The procedure is straightforward and does not require special preparation beyond avoiding stimulants beforehand. Typically, the process involves:

• A brief intake discussion covering symptoms, stress levels, and general health history
• Placement of sensors, usually on the fingers or wrist, to measure heart rate variability while seated quietly
• A short measurement period, often just a few minutes, during which the patient is asked to remain still and relaxed
• Review of results with the physician, who may relate findings to the patient's hair loss concerns and broader health picture

At Hairon Clinic, consultations involving this test may be conducted by Son Hyong-gon, Chief Director, an Internal Medicine Specialist and Regular Member of the Korean Society for Hair Research, or Kwon Ha-nim, Advisory Director and Neurology Specialist. Which physician a patient sees depends on clinic scheduling and the nature of the consultation.

Downtime and Recovery

Because the test is non-invasive and involves no needles, incisions, or medication, there is no downtime associated with it. Patients can resume normal activity immediately afterward, including work, driving, and exercise. There are no dietary restrictions after the test, though the physician may offer general lifestyle suggestions based on the results, such as stress management approaches, if relevant to the patient's overall hair loss evaluation.

Pricing

The listed non-covered fee for the Autonomic Nervous System Test is 60,000 KRW. This is a stated price for the test itself; additional consultation fees, related examinations, or VAT may apply depending on the overall visit. Patients are encouraged to confirm the total expected cost directly with the clinic before their appointment, as pricing details can be subject to change.

Safety

Heart rate variability testing is widely used in general medical settings and is considered a low-risk, non-invasive procedure. It does not involve radiation, injections, or physical intervention. That said, as with any diagnostic test, results can vary between individuals and even between measurements taken on different days, depending on factors like sleep, stress, and recent activity. Results should be interpreted by a qualified physician in the context of the patient's full clinical picture rather than viewed as a stand-alone diagnosis. Patients with specific cardiac or neurological concerns should discuss these openly with their doctor prior to testing.

Frequently asked questions

Is the autonomic nervous system test painful?

No. The test involves placing sensors on the skin, usually the fingers or wrist, and does not involve needles or discomfort.

Can this test alone diagnose the cause of my hair loss?

Not on its own. It is typically used as one part of a broader evaluation that may include scalp examination and medical history review, since hair loss usually has multiple contributing factors.

How long does the appointment take?

The measurement itself usually takes only a few minutes, though the full consultation, including intake and results discussion, will take longer. Exact timing can vary by patient.

Do I need to prepare anything beforehand?

It is generally advisable to avoid caffeine, alcohol, or stimulant medications shortly before the test, as these can affect heart rate variability readings. Otherwise, no special preparation is required.

Will I need to return for follow-up after this test?

This depends on the physician's findings and the broader hair loss evaluation. Some patients may be advised to return for further discussion or additional testing, while others may not need immediate follow-up. Individual recommendations vary.
