Biological Age Test

Sale price  $58.00 AUD Regular price  $93.00 AUD

Want to know whether your body is ageing faster or slower than your years, or curious if your diet, exercise, and sleep habits are showing up in your biology?

Analyses DNA methylation patterns to estimate biological age using validated epigenetic clock algorithms. Can be retested over time to track whether lifestyle changes have a measurable effect at the cellular level.

Overview

Biological age and chronological age are two different numbers. Your chronological age is fixed, but your biological age reflects how your cells are actually ageing based on epigenetic methylation markers in your DNA. These markers shift in predictable ways as cells age, and they are influenced by lifestyle factors including diet, exercise, sleep, stress, and environmental exposures.

This test uses validated epigenetic clock algorithms to compare your methylation profile against large population datasets. The result tells you whether your body appears to be ageing faster or slower than your years. Research links accelerated biological ageing with increased risk of age-related conditions, while decelerated ageing is associated with better long-term health outcomes. By establishing a baseline, you can measure whether lifestyle interventions are having a measurable effect at the cellular level when you retest over time.

Symptoms

To provide a data-driven estimate of biological ageing using epigenetic methylation analysis, helping to identify whether lifestyle and environmental factors are accelerating or slowing the ageing process.

Questions

  • DNA methylation is a chemical modification where small molecules (methyl groups) attach to specific points on your DNA. These marks change predictably as you age and are influenced by lifestyle and environmental factors. Analysing these patterns allows scientists to estimate biological age.
  • Different laboratories use different validated epigenetic clocks, such as the Horvath clock, Hannum clock, or GrimAge, each trained on large population datasets. The specific clock used will be indicated in your test report.
  • Research suggests that consistent lifestyle changes, including regular aerobic exercise, quality sleep, a nutrient-dense diet, stress management, and avoiding smoking and excess alcohol, are associated with improved methylation patterns over time.
  • Epigenetic clocks are among the most accurate biological age estimators currently available, but they are still an estimate. A single result should be viewed as an informative data point, not a precise measurement of health span.
  • Most practitioners recommend retesting every six to twelve months if you are actively working on lifestyle changes. Meaningful epigenetic shifts take time, so monthly retesting is unlikely to show significant differences.
  • No. Biological age is a statistical estimate of cellular health, not a prediction of how long you will live. Many factors influence longevity, and this test captures only one dimension of that picture.

How to prepare

No fasting is required for the blood draw. However, avoid intense exercise, alcohol, and significant sleep disruption in the 24 hours before collection, as acute stress and inflammation can influence methylation patterns. Let your practitioner know about any medications and supplements you are taking.

After the test

Discuss your result with your GP or a preventive health practitioner. A biological age that is significantly higher than your chronological age may prompt a broader health review covering lifestyle factors such as diet, physical activity, sleep, and stress management. Retesting after a sustained period of change can show whether your interventions are having a measurable effect.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Your result is reported as a biological age estimate. A biological age lower than your chronological age suggests your epigenetic markers reflect slower ageing. A higher biological age indicates accelerated ageing at the cellular level. No single result is definitive. Biological age is one data point among many in your overall health picture. Retesting after lifestyle changes (typically at least six to twelve months apart) can help track your trajectory over time.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

Frequently Asked Questions

Most collection centres accept walk-ins. Some may require a booking - check details when you click on your chosen location.

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

Just your pathology referral form (we email it to you)

Of course. Just maybe don’t bring the friend who faints at the sight of blood.

They’re the highly trained professionals who take your blood sample - with a steady hand and a sharp needle. They love blood, but don’t worry… they’re not vampires. Just legends who make blood tests quick, clean, and (almost) painless.

Some of our tests include Urine, Stool, Saliva and more. Each test will have a clear description on what sample you will need to give and instructions on how.
