Diagnostic Testing Procedure

The TM Flow test offers a non-invasive and efficient way to assess the health of your autonomic nervous system (ANS). Here’s the diagnostic testing procedure involved:



Before scheduling the test, discuss it with your doctor. They can advise you on any specific preparation needed and ensure the test is appropriate for your situation.

Light Meal

To reduce stomach pain during the test, it is recommended that you have a small meal a few hours beforehand.

Wear Comfortable Clothes

Consider wearing comfortable and loose clothes which allow easy access to areas and breathe your body.


Staying hydrated is a must. Drink a lot of water before the test.

Try not to be Nervous

Try to stay calm and comfortable, as the nervousness can cause unnecessary tension in your body, which can affect the treatment.

Refrain from intense exercise

Avoid strenuous exercise or any physical activities before and after the treatment. Relaxing your body is beneficial to its health.

Do not Come if You Are Unwell 

If you are not feeling well or experiencing any kind of discomfort, then it would be better to reschedule your appointments.


Inform your doctor about any medications you are currently taking, as some can have an effect on test results. They may advise you to hold certain medications for a specific time frame before the test.

The TM Flow Test Procedure

The entire procedure typically takes around 7-10 minutes.


The test is usually performed in a comfortable, temperature-controlled environment. You will sit on a chair or lie on a reclining table.


Small disposable electrodes are attached to your fingers, toes, and chest to monitor heart rate and electrical activity.

Fingertip Sensor

A fingertip sensor will be placed on your index finger to measure blood volume changes using light technology.

Sudomotor Function Testing

A mild electrical current is applied to specific areas on your skin, typically your forearm or foot, to assess sweat gland activity. This is painless and only causes a slight tingling sensation.

Cardiac Autonomic Reflex Tests (CARTs)

The healthcare professional will guide you through specific maneuvers like deep breathing, holding your breath (Valsalva maneuver), and changing positions from sitting to standing. These maneuvers help evaluate your ANS response.

Ankle-Brachial Index (ABI) Measurement

A blood pressure cuff will be placed on your arm and ankle to compare blood pressure readings. This helps assess tm blood flow test on legs.

After the Test


The TM Flow test device generates a report with various data points and analyses. Your healthcare specialist will interpret the results based on your particular situation and medical history. They will review the findings with you and, if necessary, make recommendations for the next steps.


Depending on the test results, your doctor may suggest further investigations or recommend specific treatment plans.


Remember that the TM Flow test is a diagnostic tool. The results are combined with additional clinical tests and the patient’s history to make a diagnosis. Your doctor will explain the interpretation of the results and answer any questions you have about the TM blood flow test.


Here are some frequently asked questions about the TM Flow Test:

What is the TM Flow Test used for?

The TM-Flow Test is used to assess the function of your autonomic nervous system (ANS). The ANS controls involuntary functions like heart rate, blood pressure, digestion, and sweat production. The test can help diagnose various conditions associated with ANS dysfunction, including small fiber neuropathy, cardiovascular autonomic neuropathy, and peripheral arterial disease (PAD).

Is the TM Flow Test painful?

No, the Test is completely painless and non-invasive. It involves applying small electrodes to your skin and a fingertip sensor, along with some gentle maneuvers like deep breathing and changing positions.

How long does the TM Flow Test take?

The entire Test procedure typically takes around 7-10 minutes, making it a quick and convenient option compared to traditional ANS testing methods.

Do I need any special preparation for the TMFlow Test?

There is not much special preparation required. It’s recommended to have a light meal a few hours beforehand, stay hydrated by drinking plenty of water, and discuss any medications you take with your doctor, as some may need to be temporarily paused.

What happens after the TM Flow Test?

The TM Flow device generates a report with data points and analysis. Your healthcare professional will interpret the results in the context of your medical history and discuss the findings with you. Depending on the results, they may recommend further investigations or specific treatment plans.
