Genetic Tests
Preventive Genetics
The best diagnosis is the one you never need. Preventive genetic testing reveals the risks written into your biology long before symptoms appear, then turns them into a practical plan for prevention, screening and personalised care.
Who it is for
Who should consider preventive genetic testing?
Preventive genetics is for anyone who wants to understand their risk of developing disease, in order to prevent it, monitor it, or intervene early.
Healthy people who want to prevent disease — understanding genetic risk for cancer, cardiovascular disease, neurodegenerative conditions and diabetes, and adapting lifestyle, nutrition and check-ups accordingly.
Anyone with a family history of genetic disease — cancer, early cardiovascular events, Alzheimer's, rare or inherited conditions — where testing clarifies personal risk and enables proactive measures.
Couples planning a family, through carrier screening for recessive conditions and assessment of the risk of passing a genetic condition to a future child.
Women who are pregnant or planning a pregnancy, to evaluate the risk of fetal genetic anomalies or genetically caused pregnancy loss — alongside NIPT or pregnancy-loss testing.
People focused on longevity and health optimisation, who want their diet, supplements and daily habits matched to their genetic profile.
Patients with chronic or unexplained symptoms that have been difficult to diagnose, where genetics may point towards an underlying cause.
Why it matters
Why is preventive genetic testing important?
Identifies predisposition before symptoms appear
Genetic risk is present decades before disease is. Knowing it early is what makes prevention possible rather than theoretical.
Enables proactive, personalised prevention
Results translate into concrete measures: a tailored lifestyle plan, nutrition adjusted to your metabolism, and risk factors managed early.
Allows early screening and monitoring
Where risk is elevated, surveillance for serious conditions can start earlier and run more frequently than standard population screening.
Helps clinicians personalise your care
Treatments, medication choices, diet and the schedule of medical checks can all be adapted to your individual genetic profile.
Our tests
Preventive genetic tests we offer
From a single targeted panel to the whole genome, each pathway is selected with a geneticist according to your history and your goals.
Preventive genetic panels
Assessment of genetic predisposition to common diseases, so risk can be managed long before it becomes a diagnosis.
- Cardiovascular risk, including inherited lipid disorders
- Metabolic conditions such as type 2 diabetes and obesity
- Autoimmune and inflammatory predisposition
- Neurodegenerative risk, including Alzheimer's disease
Genetic testing for hereditary cancer
Germline mutation testing for families where cancer has occurred early, repeatedly, or in more than one generation.
- BRCA1 and BRCA2 and wider hereditary cancer panels
- Breast, ovarian, colorectal, prostate and pancreatic risk
- Family history evaluation and cascade testing for relatives
- Risk-adapted surveillance plan issued with the report
Pharmacogenetic testing
How your genes influence your response to medication — a cornerstone of personalised medicine.
- CYP450 drug metabolism profile
- Guidance on statins, anticoagulants and analgesics
- Psychiatric medication response
- Reduces trial-and-error prescribing and adverse reactions
Carrier status testing
Identifies carriers of severe inherited conditions and metabolic disorders, defining reproductive risk for couples.
- Expanded carrier screening across hundreds of genes
- Recommended before conception for both partners
- Joint counselling to interpret combined results
- Links directly to prenatal options where relevant
Whole genome sequencing (WGS)
A complete genomic read for general health, wellness genetics and nutrigenetics, with the ability to reanalyse as science advances.
- Wellness and longevity genomics
- Nutrigenetics — diet, micronutrients and supplement guidance
- Exercise and metabolic response profiling
- Data retained securely for future reanalysis
Genetic counselling, before and after
Counselling is part of the test, not an add-on: it defines what is worth testing and what the result actually means for you.
- Pre-test consultation and family history review
- Plain-language interpretation of every finding
- Guidance on informing and testing relatives
- Sessions in English, Romanian and German
Good to know: Your genome is read once but used for life. Results feed into a long-term prevention and monitoring plan that is reviewed as your circumstances — and genomic science — change.
Timing
When is preventive genetic testing recommended?
There is no wrong age to start — only earlier and later points at which the information can still change what happens next.
At any age, for personal risk assessment
- Your genome does not change, so testing is valid once and for life
- Earlier results leave more time for prevention to work
Before adopting a lifestyle or treatment plan
- Nutrition, supplements and training matched to your profile
- Pharmacogenetics before starting long-term medication
When chronic disease runs in your family
- Cancer, early cardiovascular events, diabetes or dementia in relatives
- Known inherited conditions requiring cascade testing
Before conceiving a child
- Carrier screening for both partners
- Testing during pregnancy where clinically appropriate, including NIPT

FAQ
Frequently asked questions
I feel completely well — is preventive testing still worth it?
That is precisely when it is most useful. Preventive genetics identifies predisposition before any symptom appears, which is the only point at which prevention, earlier screening and lifestyle change can still alter the outcome.
Does a genetic risk mean I will develop the disease?
No. Most results describe probability, not certainty. Genes interact with lifestyle and environment, and knowing an elevated risk is what allows you to act on the factors you can control.
How does family history fit into the assessment?
A detailed family history is taken at the consultation and shapes which tests are appropriate. Patterns of early or repeated disease across generations often determine whether a hereditary panel is indicated.
What is pharmacogenetics and why does it matter?
It analyses how your genes affect the way you metabolise medication. The results help your doctor choose the right drug and dose from the outset, reducing side effects and ineffective treatment.
What is the difference between wellness genetics and clinical testing?
Wellness genetics and nutrigenetics guide diet, supplements and lifestyle. Clinical testing, such as hereditary cancer panels, informs medical surveillance and treatment decisions. We offer both and will advise which you actually need.
Is genetic counselling included?
Yes. Counselling before and after testing is part of every preventive genetics pathway at Hilmi Lab, and includes a long-term prevention and monitoring plan.
