Introducing the TruAge biological age test

Curious to know your real age and get insights on how your diet and lifestyle are impacting it? We proudly offer access to the groundbreaking TruDiagnostics TruAge biological age test, the best biological age test in Australia, a way to understand your health like never before.

While chronological age is fixed, biological age is shaped by your factors like your diet, exercise, rest, and stress management, and reflects the true effects of your lifestyle choices. TruAge offers a detailed assessment of your biological age, telomere length, and your pace of ageing, to help you actively manage your wellbeing.

To ensure you get the most out of the wealth of data provided in the TruAge reports, our functional medicine practitioners will help you make sense of your results.

The science behind TruAge test

TruDiagnostic, the pioneering force behind the TruAge biological age test, delves deep into your DNA’s methylation patterns. These patterns are then subjected to advanced algorithms fueled by machine learning and decades of research.

TruAge doesn’t just stop at revealing your biological age. It provides a comprehensive ecosystem of insights from a single blood spot test. Your TruAge Complete reports include:


Published in 2023 with Harvard, your OMICm Age is the most accurate measure of biological age to date. Your OMICm Age also provides insight into WHY you’re ageing, through the multiome. This helps determine what actions will be effective in reversing your biological ageing.

Page of ageing

An algorithm developed over five decades of longitudinal research, the DunedinPACE biological clock provides insights into your current rate of ageing, providing unmatched accuracy against other biological age clocks. This gives you the ability to measure the effect of your recent health efforts.

Telomere length

Telomere length is an indicator of the ageing process and a wide variety of diseases. TruAge estimates telomere length through DNA methylation patterns to enhance the precision of your biological age calculation, and improve predictions of disease risk.

Epigenetic biological age

Your epigenetic biological age is primarily determined by DNA methylation, a reliable biomarker for health and prediction of disease risk. Your intrinsic biological age is independent of age-related changes associated with immune ageing, whereas extrinsic age calculates age acceleration associated with your immune system.

Browse our FAQs by category below.

What happens after I order the TruAge test and interpretation session?

Your TruAge biological age test kit will be sent to your location of preference. Once you’ve submitted your test and your results are back, our health concierge will be in touch to book your interpretation session with one of our functional medicine practitioners.

Note that the TruDiagnostics lab is in the US, so test results can take up to six weeks to come back.

Can I do the TruAge test at home?

Yes, the TruAge test kit includes everything required to easily perform the test at home. It’s a quick and straightforward blood spot test that takes less than a few minutes to complete. Simply place your sample in the provided postage-paid return envelope and send it off to the lab. Detailed instructions are included with your kit to ensure a smooth process from start to finish.

How long do TruAge test results take to come back?

Results are usually back within six weeks of the lab receiving the test sample. We’ll notify you when your results are back.

How does the TruAge test work?

Your biological age is the age of your body, primarily determined by DNA methylation – which regulates gene expression by turning genes on or off. This epigenetic mechanism influences whether certain genes promote health or disease. DNA methylation is a strong biomarker for assessing biological age, health and prediction of disease risk.

The TruAge biological age test takes the blood sample you’ve provided, and extracts the DNA. It then assesses over 900,000 methylation sites in your DNA to determine what genes are being methylated. Certain patterns of methylation are strongly correlated with age. Your methylation pattern will be assessed against established ageing models and research datasets to determine your biological age.

The test also uses the DunedinPACE clock, which will then calculate your pace of ageing by evaluating how quickly your biological functions are changing relative to the general population. This offers a more dynamic perspective on your ageing process, helping to predict health trajectories and potential interventions.

Can I retest my biological age?

Yes! We often suggest retesting in 3-6 months to assess whether the interventions you’ve implemented have shifted your biological age and pace of ageing in a favourable direction. Rather than order the TruAge Complete test, you can order the TruAge PACE test.

What happens at the interpretation session?

Your practitioner will interpret the TruAge test results in a way that is clear and informative. There’s a wealth of data in the TruAge test, so your practitioner will use their knowledge and skills to interpret the results in a meaningful way.

If you’d like further support in the way of a health optimisation plan, and ongoing support, the next step would be to book a kickstart session to start your partnership with us. In the kickstart session, you’ll discuss your current health picture and health goals with your practitioner, to work out the next best steps to get you to your health goals.

Prices are valid as of April 2024, and are subject to change.

What factors contribute to the price of this test?

There are many biological age tests on the market and vary from very cheap to very premium. We choose TruDiagnosic tests as they use the best methodology, algorithm and tissue sample, being blood.

The cheapest tests on the market use old methodology, narrow methodology, or saliva. Blood is most accurate, because its unique signature provides more accurate results than other tissues. It has control features like cell deconvolution methods which allows the lab to know what cell types are present, at what percentage, so they can make sure what tissue type can be controlled for. Also, most researchers work with blood, making it a standard for analysis. It ensures compatibility with new algorithms being developed as their data is consistently generated in blood.

Another reason is that blood is more stable than saliva DNA, as behaviours like smoking can have a drastic impact on saliva DNA methylation, while blood remains more reliable for epigenetic analysis.
