Testing
Preventative-First.
Your bloodwork shows how your biology is performing today. Your genome reveals the lifelong predispositions and metabolic tendencies that make genuinely preventative care possible. The Catalyst Clinic is the only clinic in Europe to offer anywhere integrated accredited genetic testing directly into a physician-led peptide and supplementation programme — from a single blood draw, reviewed personally by Dr. Ethan Hausman-Marquis.
Genetic and genomic testing is provided as accredited clinical diagnostic testing, distinct from the peptide research compounds discussed elsewhere. A result indicating elevated risk is not a diagnosis. Predisposition testing is accompanied by a registered genetic counselling service.

Why Test Your DNA
Preventative Health, Written In Your Genome.
Most health data is a snapshot. Bloodwork tells you how your body is functioning on the day it was drawn — invaluable, but temporary. Your genome is different: it does not change, and it carries the deeper context of the predispositions and metabolic tendencies you have held since birth.
Reading that context lets us move from reactive to genuinely preventative. Rather than waiting for a marker to drift out of range, we can anticipate where your biology is most likely to need support and build your programme around it from the outset — the right form of a nutrient, the systems worth watching most closely, the areas where early attention pays off.
At The Catalyst Clinic your results are never a report filed away. Every panel is reviewed personally by Dr. Ethan Hausman-Marquis — PhD, Cell and Genomic Biology, Karolinska Institute — and integrated directly into your AURION™ supplementation plan and your monitoring schedule.
What Your Genome Informs
- How you absorb and use key vitamins — feeding your AURION™ plan
- The right form of a nutrient for your biology (e.g. methylfolate vs. folic acid)
- Your genetic baseline Omega 3:6 ratio and inflammatory tendency
- Caffeine metabolism and fasting response
- Inherited cardiac, cholesterol and iron-handling predispositions
- Cancer predisposition — informing screening and monitoring cadence
- Gut microbiome composition and diversity
- Which biomarkers to track most closely over the life of your programme
The Panels
Tests Available & What Each One Does
Every panel below can be added to your programme. Which panels are appropriate is a decision Dr. Ethan makes with you, guided by your history, family history and goals — never a blanket recommendation.
Nutrigenomic — Directly Feeds Your Supplementation
The genomic layer that most directly shapes your AURION™ plan, translating your DNA into precise, personalised supplementation.
Nutrition & Lifestyle DNA
Nutrigenomic Profile
Personalised insight into how your biology handles key nutrients — vitamin absorption, folate and vitamin D deficiency risk, your baseline Omega 3:6 ratio and inflammatory tendency, fasting response, and caffeine metabolism. The panel that most directly translates into your AURION™ morning and evening formulations.
Genetic Lactose Intolerance
Nutrigenomic Profile
Genotyping of the lactase-persistence variants that determine whether your body continues to produce lactase into adulthood — clarifying whether dairy is a genuine trigger and informing dietary and supplementation guidance.
Microbiome Testing
Metagenomic Sequencing
In-depth shotgun sequencing of the gut microbiome, identifying 30+ biomarkers — overall diversity, the Firmicutes/Bacteroidetes ratio, probiotic and potentially harmful species, fibre-degrading and butyrate-producing bacteria, plus fungi, archaea and viruses. Informs targeted dietary and gut-support recommendations.
Cardiometabolic & Metabolic Predisposition
Inherited tendencies that shape which systems your programme monitors most closely and how often we repeat your bloodwork.
Genetic Full Cardiac Risk
Inherited Cardiac Conditions
A next-generation sequencing screen covering over 100 genes associated with inherited cardiac conditions — cardiomyopathies, channelopathies and aortopathies. Particularly relevant where there is a family history of cardiac disease or unexplained cardiac symptoms.
Familial Hypercholesterolaemia
Inherited Cholesterol Risk
Screens five genes for variants that drive genetically elevated cholesterol and premature cardiovascular risk. Relevant for adults with unexplained high total or LDL cholesterol, or a family history of early heart disease.
Genetic Haemochromatosis
Iron Overload Risk
Genotyping of three HFE variants commonly associated with hereditary iron overload. Especially relevant for those of Northern European ancestry with unexplained raised ferritin or transferrin saturation — guiding iron-related monitoring and supplementation decisions.
Digestive & Autoimmune Predisposition
Clarifying genetic drivers behind digestive symptoms so guidance is targeted rather than trial-and-error.
Genetic Coeliac Disease
Autoimmune Predisposition
Genotyping for the HLA-DQ2 and HLA-DQ8 haplotypes, which are present in up to 99.7% of coeliac patients. A negative result effectively rules out coeliac disease — useful for anyone with chronic digestive symptoms, fatigue, or a family history.
Specialist Oncology — Cancer Predisposition
Hereditary cancer-risk panels. These carry meaningful personal and family implications and are always accompanied by our complimentary genetic counselling service, before and after testing.
Breast & Ovarian Cancer Risk
Hereditary Cancer Panel
Screens eight genes for variants that may increase risk of breast and ovarian cancer — relevant where there is a personal or family history, or Ashkenazi Jewish ancestry.
Bowel Cancer Risk
Hereditary Cancer Panel
Screens 11 genes linked to hereditary bowel cancer and Lynch Syndrome — relevant where there is a personal or family history of bowel or Lynch-related cancers.
Prostate Cancer Risk
Hereditary Cancer Panel
Screens 14 genes for variants that may increase prostate cancer risk — relevant where there is a personal or family history of prostate cancer, or Ashkenazi Jewish ancestry.
Core Cancer Genetic Risk
Comprehensive Panel
A broader screen of 29 genes covering variants associated with common cancers — including breast, bowel, prostate and ovarian. Suited to those with a wider family history or where a smaller panel returned no variant.
Genetic Full Cancer Risk
Most Comprehensive Panel
Our most comprehensive hereditary screen — 94 genes covering variants linked to both common and rare cancers. The deepest predisposition picture available, for those who want the fullest genomic context.
A note on the oncology panels: hereditary cancer-risk testing has significant personal and family implications and is never entered into lightly. Every predisposition panel at The Catalyst Clinic includes access to a registered genetic counsellor for both pre-test and post-test discussion. A result indicating elevated risk is not a diagnosis — it is information that guides screening, monitoring and, where appropriate, onward specialist referral.
Integration
How Your Genome Shapes Your Programme.
Genetic data is only valuable when it changes what we actually do. At The Catalyst Clinic your results are integrated into three parts of the Catalyst Method — reviewed personally by Dr. Ethan, never by algorithm.
01
Precision Supplementation
Your Nutrition & Lifestyle DNA results flow directly into your AURION™ plan. A folate-processing variant may mean methylfolate rather than folic acid; a vitamin D absorption tendency informs dosing; your genetic Omega 3:6 baseline guides EPA/DHA. Supplementation matched to your biology, not a generic stack.
02
Targeted Monitoring
Predisposition data tells us which systems to watch most closely. A cardiac or cholesterol predisposition means tighter lipid and cardiovascular monitoring and, where indicated, more frequent bloodwork — so your programme is genuinely preventative rather than reactive.
03
A Life-Long Baseline
Unlike bloodwork, your genome does not change. Established once, it becomes a permanent layer of context beneath every future review — informing how your advisory programme evolves and where preventative attention is best directed over the years ahead.
The Process
Simple To Begin. Fully Supported.
From a single blood draw to a report you can actually understand — with a registered genetic counsellor available at every stage of the predisposition panels.
Step 01
Consultation & Panel Selection
Dr. Ethan discusses your history, family history and goals, and helps you decide which panels are genuinely worthwhile for you. Optional pre-test genetic counselling is available for the predisposition panels.
Step 02
A Single Blood Draw
Most panels require only one blood sample, taken in clinic or by arrangement. The microbiome panel uses a simple home-collection kit. No repeat visits to begin.
Step 03
Accredited Laboratory Analysis
Your sample is processed through accredited laboratories using clinical-grade sequencing and PCR. Turnaround ranges from seven days to six weeks depending on the complexity of the panel.
Step 04
Physician Review & Counselling
Dr. Ethan reviews your results personally and you receive a clinical report written to be understood. Predisposition results are accompanied by complimentary post-test genetic counselling.
Step 05
Integration Into Your Programme
Your genomic data is folded into your AURION™ supplementation plan and your monitoring schedule — becoming a permanent layer of context beneath every future review.
Step 06
Ongoing Preventative Care
Because your genome does not change, it continues to inform your care indefinitely — guiding where preventative attention is best directed as your programme evolves over the years ahead.
Why The Catalyst Clinic
Genomics, Integrated — Not Isolated.
Many providers will sell you a genetic test and a PDF. Very few anywhere fold that data into a physician-led peptide and supplementation programme, reviewed personally and revisited at every appointment. That integration is the difference between an interesting report and genuinely preventative care.
01
Physician-Reviewed, Not Automated
Every result is read personally by Dr. Ethan Hausman-Marquis — PhD, Cell & Genomic Biology, Karolinska Institute. No algorithm-only interpretation, no delegation.
02
Integrated With AURION™
Your nutrigenomic data flows directly into your supplementation plan — the right form and dose of each nutrient for your biology, not a generic stack.
03
Counselling-Supported
Predisposition panels include a registered genetic counsellor for pre- and post-test discussion — so results are understood and handled responsibly.
04
Accredited Laboratories
Clinical-grade sequencing and PCR through accredited laboratories, with reports written in plain language alongside the science.
05
A Lifelong Baseline
Tested once, your genome informs your care indefinitely — a permanent layer of context beneath every future review and adjustment.
