Nutrigenomix nutrigenetic test
The Nutrigenomix test is a complementary tool that analyses certain genetic variations associated with nutrient metabolism. The results are interpreted with the dietitian in the context of your health, your eating habits and your goals.
Total price for 3 sessions, genetic test included (€160.00 per session). The length of each session is agreed with you when booking.

Nutrigenetic test analysing 70 genetic markers, interpreted in the context of your diet, lifestyle and medical situation.
Offered in Luxembourg by Gabriela Ferent, State-certified dietitian-nutritionist.
What is a nutrigenetic test?
Nutrigenetics studies how certain variations present in our genes may contribute to the individual differences observed in the metabolism or the use of certain nutrients.
These variations alone do not determine your health: diet, physical activity, sleep, medical context and environment play a role that is at least as important. The test therefore provides one piece of information among others, never a standalone conclusion.
Who might it be for?
The test is not necessary for anyone. It may simply be considered, after discussion in consultation, if you would like:
- an additional level of personalisation for your dietary recommendations
- a prevention-oriented approach, in addition to your dietetic follow-up
- to better understand certain individual characteristics related to your nutrition
The relevance of the test is assessed case by case during the dietetic assessment. In many situations, standard nutritional support is enough.
The 7 areas analysed
According to the official documentation of the Nutrigenomix® Health & Wellness panel, the test analyses 70 genetic markers grouped into seven categories. The list below describes the panel content — that is, what is measured. It establishes no diagnosis and prejudges no result.
Cardiometabolic health
Caffeine · Sodium · Omega-3 · Saturated fat · Whole grains
Characteristics analysed in relation to blood pressure, blood lipids and caffeine metabolism.
Nutrient metabolism
Vitamins A · B12 · C · D · E · Folate · Iron · Calcium
Variants associated with requirements and status for certain vitamins and minerals.
Weight management & body composition
Physical activity · Energy balance · Protein · Total fat · Monounsaturated fat · Saturated vs unsaturated fat
Characteristics studied in trials on macronutrient distribution and physical activity.
Food intolerances
Lactose · Gluten
Genetic predispositions analysed by the panel. Diagnosing an intolerance or coeliac disease remains a matter for your doctor.
Eating habits
Fat taste perception · Sweet preference · Eating between meals · Starch digestion
Characteristics describing certain taste preferences and perceptions.
Physical activity
Exercise motivation · Exercise behaviour · Power and strength · Endurance
Panel characteristics related to physical activity, described for information.
Injury risk
Pain · Achilles tendon
Panel characteristics related to pain and the Achilles tendon.
The characteristics related to physical activity and injury risk are part of the panel: they describe the test content. The practice does not offer a sports-preparation or performance service.
How the test works, step by step
- 1
Non-invasive saliva sample (5 min)
Taken simply and painlessly at the Luxembourg-City, Ettelbruck or Insenborn practice.
- 2
Analysis in a CLIA-certified, CAP-accredited laboratory
DNA analysis performed under strict quality and confidentiality standards.
- 3
Detailed personalised report
An individual genetic report grounded in published scientific studies.
- 4
Dietetic interpretation consultation
Your results are translated into concrete dietary directions, discussed with your dietitian.
Examples of results and how they are read
These examples are illustrative: they are not your results. Each separates three levels: what the test measures, the association observed in published studies (a group average, never an individual guarantee), and what is then discussed in consultation.
Measured
Caffeine — slow metaboliser (C-allele carrier: AC or CC)
Observed association
In observational studies, higher coffee intake is associated with increased cardiovascular risk in slow metabolisers, but not in fast metabolisers (AA).
In consultation
Your personal caffeine reference point is discussed in light of your blood pressure, sleep and medication.
Cornelis et al., JAMA 2006 ; Palatini et al., J Hypertens 2009.
Measured
Folate — TT genotype, associated with reduced enzyme activity
Observed association
The TT genotype is associated with higher homocysteine, particularly when folate intake is low.
In consultation
Attention given to folate-rich foods, with no automatic supplementation and no product sales.
Hiraoka & Kagawa, Congenital Anomalies 2017 ; méta-analyse rs1801133, Am J Clin Nutr 2023.
Measured
Protein — carrier of the BMI-associated variant
Observed association
In the randomised POUNDS Lost trial, carriers of this variant showed a more favourable change in body composition on a diet providing 25 % of energy as protein.
In consultation
This is a group average: the distribution that suits you is built with you, not deduced from the gene.

Scientific foundation
Nutrigenomix® was developed by researchers at the University of Toronto, led by Dr Ahmed El-Sohemy, and is supported by an international science advisory board (Harvard, UC Davis, Tufts).
Recommendations come from published, peer-reviewed studies and are interpreted at the practice within the context of your dietetic assessment.
Non-diagnostic tool. It supports personalised nutritional optimisation under professional dietary supervision and replaces neither a medical examination nor prescribed treatment.
What the test can provide
The test can provide complementary information that may help the dietitian refine selected nutritional recommendations already established during the assessment: dietary priorities, points to keep an eye on and practical adjustments to the follow-up plan.
The characteristics analysed depend on the selected panel. They are presented and explained to you before any sample is taken, so that you know exactly what will be studied.
What the test cannot do
The test does not establish a medical diagnosis, does not predict with certainty the development of a disease and replaces neither laboratory tests, nor medical evaluation, nor the dietetic assessment.
It must not be used to diagnose a food allergy, lactose intolerance, fructose intolerance, coeliac disease or any other medical condition. These situations require medical evaluation and specific examinations.
Confidentiality of genetic data
Genetic data are particularly sensitive health data. They are processed only with your explicit, prior and written consent, solely as part of your dietetic care, and are never used for commercial purposes or shared with third parties without a legal basis.
Frequently asked questions
- Does the test need to be repeated?
- No. Your DNA does not change: the test is done once in a lifetime. Only the interpretation evolves with your goals and with scientific knowledge.
- What does it cost and is it reimbursed?
- This is a private service, not covered by the CNS. The rate for the “Nutritional + genetic assessment (3 sessions)” package is shown at the top of this page and on the Rates page.
- What happens to my genetic data?
- Your data is processed by the laboratory under strict confidentiality and is never used commercially by the practice. Detailed terms (retention, recipients, deletion) are presented to you before sampling.
Is this test right for your situation?
The test is never sold online. It is considered only after a discussion with the dietitian, as part of a consultation.
