Neurotransmitter metabolites test

Determine the activity of your neurons

This test identifies whether your production of Dopamine, Serotonin and Noradrenaline is sufficient.

These chemical compounds adjust the traffic of your neurons and their balance is therefore essential to your well-being. Dopamine gets your day off to a good start, noradrenaline is the engine that keeps you working throughout the day and serotonin helps you cope with stress and frustration.

Your mood, your emotional balance, your learning capacity, your resistance to addictions and the restorative effect of your sleep can all be strongly affected by your production of neurotransmitters.


What does the test include?

  • Home-delivered sample collection kit

  • Analysis of your samples by our functional biology medical laboratory

  • Receipt of your test results and their comprehensible explanations

  • Recommendations for diet and supplementation, together with a personalised programme based on your analysis results.

Neurotransmitters

Dopaminergic axis: Homovanillic acid (HVA) is used to assess levels of the neurotransmitter dopamine.

  1. HVA is the substance created when dopamine is broken down after it has been used by our neurons and is eliminated in the urine. A high concentration of HVA in the urine will therefore mean a high production of dopamine and vice versa.

  2. Dopamine is the hormone that gets the day started. It is involved in motor control, attention, pleasure, motivation, memory and cognition. Also known as the happiness hormone or pleasure hormone, dopamine plays an important role in behaviour.

Noradrenergic axis: 3-Methoxy-4-HydroxyPhenyl Glycol (MHPG) is used to assess levels of the neurotransmitter noradrenalin.

  1. MHPG is the substance created during the breakdown of noradrenalin after it has been used by our neurons, and is eliminated in the urine. A high concentration of MHPG in the urine will therefore mean a high production of noradrenalin, and vice versa.

  2. Noradrenalin is the engine that keeps us going. Its hormonal action enhances alertness and attention, and improves our ability to react to potentially dangerous events. It is associated with an increase in heart rate and blood pressure.

Serotonin axis: 5-Hydroxy-Indol-Acetic Acid (5HIA) is used to assess levels of the neurotransmitter serotonin.

  1. 5HIA is the substance created when serotonin is broken down after it has been used by our neurons and is eliminated in the urine. A high concentration of 5HIA in the urine will therefore mean a high production of serotonin and vice versa.

  2. Serotonin is involved in regulating mood, anxiety, sleep. It is the hormone of calm, of patience. It helps us cope with stress and frustration. It also plays a role in the production of melatonin, known as the "sleep hormone".

  3. 95% of this serotonin is produced in the intestine and only 5% in the brain. The level of 5 HIA that we observe in your urine is the result of total serotonin production and therefore essentially that produced in your intestines. A high level of 5HIA is therefore a marker of intestinal disturbance. Your intestine produces too much serotonin. The serotonin receptors in your intestine are therefore hyperstimulated, which can generate colic and pain.

What about anti-depressants?

This approach is different from, but complementary to, taking antidepressants.

The aim of most antidepressants is to facilitate the binding of neurotransmitters to so-called neurotransmitter receptors. However, they do not help to produce these neurotransmitters. These antidepressants are therefore ineffective if you do not produce enough neurotransmitters.

This analysis enables us to assess your level of production of these neurotransmitters. Whether or not you are taking antidepressants. Depending on the results of this analysis, we can recommend natural solutions to increase your neurotransmitter production if it is too low.

How does the analysis work?

It is a urine analysis. It is used to assess whether your production of the neurotransmitters Dopamine, Noradrenaline and Serotonin is sufficient by analysing the presence of certain metabolites in your urine.

The urine is collected in a container which you then send free of charge to the laboratory using a pre-stamped label. The quality of your samples is ensured by the isothermal box that is sent to you to keep the sample at a temperature below 8°C during transport.

What's the difference with a health check?

The tests offered are not those required as part of a basic check-up. These basic check-ups are designed to rule out an illness (such as an infection, a generalised infection, hepatitis, a virus, anaemia, etc.) and not to assess any malfunctions in the body that may be at the root of chronic symptoms;

Why haven't these analyses been offered to you yet?

These tests help to identify the causes of chronic discomfort rather than acute illness. GPs tend to recommend general health check-ups to detect acute or sub-acute illness. In the case of chronic discomfort, these check-ups generally offer no solutions;


The use of these analyses requires specific knowledge of functional biology. They are therefore generally recommended by doctors with training in the field - which is not yet the case for all referring doctors.

What is chronic discomfort?

Chronic discomfort is characterised by a number of factors: 

  • The cause cannot be detected in a general health check-up and there is no precise drug treatment

  • They disrupt our quality of life considerably

  • We don't die from them

  • The treatments tried have not been effective
