How Old Is Your Body,Really?
Your chronological age is fixed. Your biological age — the age your cells are actually functioning at — is not. TruAge epigenetic testing measures the difference and identifies how fast you are ageing right now.

Panel
What's Covered
Biological age is a measurable property of your DNA — specifically, of the patterns of chemical tags called methylation marks. These marks regulate which genes are switched on or off and change in highly predictable ways as we age. EGA uses TruAge by TruDiagnostic, a clinically validated and widely used epigenetic test.
01Biological Age
Your overall biological age based on validated population data. If your biological age is lower than your chronological age, your results suggest you are ageing more slowly than average.
02DunedinPACE — Pace of Ageing
The most clinically significant metric. It measures how fast you are ageing right now. A score of 0.8 means your biology is ageing 20% slower than average; 1.2 means 20% faster. Repeat testing can help track whether lifestyle or clinical changes are having an effect.
0311 Organ-Specific Ages
Your biological age broken down by organ system, including cardiovascular, immune, metabolic, kidney, liver, hormonal, and brain-related systems. This allows for targeted rather than generic intervention.
04Telomere Length Estimation
Estimated telomere length derived from methylation data. Short telomeres are associated with accelerated ageing and increased disease risk.
05Immune Cell Composition
A breakdown of immune cell types revealing how your immune system is constituted and how it is ageing at the molecular level.
06Lifestyle Impact Scores
Epigenetic signals associated with alcohol consumption, smoking history, and weight status. These provide a molecular read on their impact, independent of what you report.
Blood-based testing is significantly more accurate than saliva-based alternatives, which can show variability of up to 25 years between samples.

Audience
Who It's For
This test is designed for those seeking an objective, molecular measure of their ageing trajectory and response to lifestyle changes.
- People wanting to know if their lifestyle is ageing them faster or slower than average
- Those who have made significant changes to diet, exercise, or sleep and want to see if they are registering at the cellular level
- Individuals with a family history of age-related disease wanting an early biological indicator of their trajectory
- People pursuing a comprehensive longevity assessment who want epigenetic data alongside biomarker results
- Anyone wanting a sensitive measure of whether their longevity interventions are working

Deliverable
Actionable Results and Clinician Review
Your results are not returned for you to interpret alone. A doctor reviews your findings to provide written commentary and context.
- A comprehensive TruAge report including biological age and DunedinPACE scores
- Doctor commentary contextualising your findings within your full health picture
- Identification of specific interventions most relevant to your individual results
- Flagging of any findings that suggest follow-up through further testing or clinical consultation
- A clear baseline from which to track your ageing trajectory over time

Difference
The Power of Epigenetic Modification
DNA methylation patterns are directly influenced by the choices and conditions that make up your life. Your TruAge result is a reflection of everything your lifestyle has done to your biology — and it may change over time.
Stress and Sleep
Chronic stress accelerates epigenetic ageing, while high-quality sleep is one of the most powerful modulators of epigenetic health.
Nutrition and Exercise
Anti-inflammatory diets and regular exercise have well-documented effects on DNA methylation patterns, with some studies showing biological age reductions of several years.
Venous Blood Accuracy
EGA uses venous blood draws — the same type used in clinical research — which are more accurate and produce higher-quality DNA than consumer finger-prick samples.
Professional Context
Results are reviewed by a doctor who provides written commentary, ensuring your data is used to inform practical and safe longevity interventions.

Questions
Common Questions
What is DNA methylation?
DNA methylation is a chemical modification where methyl groups attach to specific sites on your DNA. These marks regulate gene expression and change in predictable patterns as we age. By measuring these marks across hundreds of thousands of sites, epigenetic clocks can estimate biological age with high accuracy.
How is this different from a genetic test like 23andMe?
A genetic test reads your fixed DNA sequence, which does not change. An epigenetic test reads the methylation marks 'on top' of your DNA, which change in response to your lifestyle, environment, and the biology of ageing. It tells you how your genes are being expressed right now.
What is DunedinPACE and why does it matter?
DunedinPACE is a validated algorithm that measures your current rate of biological ageing. It is a dynamic score rather than a static age estimate, making it a sensitive tool for detecting whether your current interventions are slowing or accelerating your ageing.
Can I reduce my biological age?
Yes. Epigenetic age is modifiable. Evidence-based interventions include regular exercise, high-quality sleep, anti-inflammatory nutrition, stress reduction, and targeted supplementation. Retesting after focused intervention is the most direct way to verify if these changes are working.
How long do results take?
Your clinician-reviewed report will be available in approximately 2 to 3 weeks from your blood draw.
Do I need to fast before the test?
No fasting is required for the TruAge blood draw.
How often should I retest?
Retesting every 6 to 12 months is appropriate for most people. Significant lifestyle changes take time to register epigenetically; a 6-month interval is the minimum for meaningful comparison.
Why is blood testing better than saliva?
Blood-based testing is significantly more accurate and consistent. Saliva tests can show variability of up to 25 years between samples, whereas blood samples provide stable, high-quality DNA suitable for clinical research.
