Get the complete picture of your genetic health with this comprehensive test combining DNA analysis (187+ genetic markers) with epigenetic profiling (biological age and methylation markers)—all from a single saliva sample. This is the most complete foundation for personalised health optimisation available.

Your DNA reveals your fixed genetic blueprint—the traits, predispositions, and metabolic tendencies you were born with. Your epigenetics reveal what you're doing with that blueprint—how your lifestyle is actively turning genes on or off, and how old your body is at the cellular level. Together, they answer two fundamental questions: what are you working with, and how well is it working?

This combination is ideal for serious biohackers, longevity enthusiasts, athletes, and anyone committed to making evidence-based decisions about their health. Results include 12 months of complimentary access to MAISIE, your AI Health Coach who integrates both datasets to provide uniquely personalised recommendations.

Why Choose This Test?

  • One sample, two analyses – Single saliva collection provides material for both DNA and epigenetic testing
  • 187+ DNA markers – Comprehensive genetic analysis across 20+ health categories
  • 7 age biomarkers – Biological age, memory age, eyesight age, hearing age, inflammation, immune function
  • Fixed + dynamic – DNA shows what you're born with; epigenetics shows what you're doing with it
  • 12 months AI Health Coach – MAISIE integrates both datasets for truly personalised guidance
  • Best value – Save £125 compared to purchasing both tests separately

🧬 DNA Analysis Reveals:

  • Your genetic nutrient metabolism
  • Optimal exercise type for your genes
  • Vitamin absorption variants
  • Sleep and stress genetics
  • Hormone and gut health markers
  • Injury risk and recovery traits

🔬 Epigenetic Analysis Reveals:

Results in 3–4 weeks

Results are available within 3–4 weeks from the sample arriving at Eurofins laboratory. You'll receive separate detailed reports for both DNA and epigenetic markers, plus integrated AI-powered recommendations through MAISIE.

Important: Register your kit online using your unique Kit ID before posting. This links your sample to your account for results delivery. You will not receive results without completing registration.

How It Works

We'll send you a saliva collection kit with a collection tube, funnel, stabilising solution, simple instructions, and a prepaid return envelope. One sample provides sufficient material for both DNA and epigenetic analysis—no need to collect twice. Just deposit saliva into the tube until it reaches the fill line. No needles, no blood, no clinic visit needed.

Before collection: Do not eat, drink (except water), smoke, or chew gum for at least 30 minutes. This ensures your saliva is free from contaminants.

Your kit includes: Saliva collection tube with funnel, stabilising solution cap, biohazard specimen bag, prepaid return envelope, step-by-step instructions, and kit registration card.

Who Is This For?

  • Serious biohackers wanting the complete picture of their genetic health
  • Longevity enthusiasts looking to optimise both their genetic potential and biological age
  • Athletes wanting to align training with genetics AND track recovery/ageing impacts
  • Anyone committed to evidence-based health decisions with comprehensive data
  • People wanting to establish a baseline and track improvements over time
  • Those seeking the best value—save £125 vs purchasing both tests separately
Sleep & Stress Response 😴
Discover your genetic chronotype and stress resilience—whether you're a morning person or night owl, and how you handle pressure.
Chronotype & Sleep Need Natural rhythm, sleep duration requirements
COMT & Stress Response Warrior vs Worrier, stress hormone clearance
Heart & Gut Health ❤️
Identify genetic factors related to cardiovascular health, cholesterol metabolism, lactose tolerance, and coeliac risk.
Cardiovascular Markers LDL/HDL, blood pressure, inflammation
Lactose & Coeliac Risk Lactase persistence, HLA-DQ2/DQ8

Additional DNA categories include: Skin Health, Hair Health, Eye Health, Detoxification, Caffeine & Alcohol Metabolism, Weight Management, Psychological Traits, Immune Function, Longevity Markers, and more.

Overall Biological Age 🧬
Your true cellular age based on DNA methylation patterns. Unlike chronological age, biological age reflects how your lifestyle choices are affecting ageing at the molecular level—and can be improved through targeted interventions.
Memory Age 🧠
Epigenetic markers linked to cognitive function, neuroplasticity, and brain health. Influenced by sleep quality, mental stimulation, diet, exercise, and stress management.
Eyesight Age 👁️
Evaluates epigenetic markers related to retinal and optic nerve health. Influenced by UV exposure, dietary antioxidants, screen time, and metabolic health.
Hearing Age 👂
Examines epigenetic markers associated with auditory system health. Influenced by noise exposure, oxidative stress, inflammation, and cardiovascular health.
Inflammation Score 🔥
Chronic low-grade inflammation ("inflammaging") is a key driver of accelerated biological ageing. This analysis examines methylation patterns in inflammatory pathway genes.
Immune Function 🛡️
Evaluates epigenetic markers related to immune system health, including immune cell differentiation and cytokine production. Informs strategies to support optimal immune function.
DNA Methylation Patterns 🔬
DNA methylation is the epigenetic mechanism that turns genes on or off based on your lifestyle. By analysing these patterns, you can see how diet, stress, exercise, sleep, and environment are programming your health at the genetic level.

MAISIE is your personal AI Health Coach, included free for 12 months with this combined test. Unlike the standalone tests, MAISIE integrates BOTH your DNA and epigenetic data to provide truly comprehensive, personalised guidance.

What MAISIE offers with combined data:

  • Personalised nutrition recommendations based on your genetic metabolism AND current biological state
  • Exercise guidance aligned with your genetic strengths AND tracking recovery impact on biological age
  • Supplement suggestions based on genetic needs AND current inflammatory/immune status
  • Strategies to reduce biological age by leveraging your genetic advantages
  • Integrated insights that neither test alone could provide
  • Ongoing support as you implement changes and retest epigenetics

Access MAISIE through the online portal once your results are ready. The combined dataset allows for far more nuanced and powerful recommendations than either test alone.

Good to Know

This combined test provides both your fixed genetic code (DNA) and your current biological state (epigenetics). Your DNA results are permanent—you never need to repeat that portion. Your epigenetic results are dynamic—consider retesting every 6–12 months to track biological age improvements.

For future retesting, you can purchase the standalone Biological Age Test to measure your progress without repeating the DNA analysis.

Results should be discussed with a qualified healthcare professional, particularly if they relate to disease risk or medical decision-making. UK delivery only. Non-refundable once dispatched. This test is not a substitute for professional medical advice, diagnosis, or treatment.

Sample Collection: Saliva sample collected at home.

No Fasting Required.

Results Timing: 3-4 weeks.

Genetic Counselling: Recommended for interpreting genetic risk results.

No clinics, no queues, no hassle
