Optimise Longevity & Healthy Ageing
Understanding how your body is ageing is one of the most important steps you can take to protect your long-term health. Our scientifically backed longevity tests help you track key ageing biomarkers, uncover hidden risks and optimise your healthspan. From biological age testing and methylation analysis to DNA health insights and cardiovascular ageing tests, these panels give you a complete picture of how well your body is functioning now — and what you can do to age well for the future. Whether you want a simple biological age test or the most advanced longevity assessment available, our tests help you take control of your long-term wellbeing with clarity and confidence. Order online, no GP referral needed.

What is your true biological age?
Your biological age reflects how fast your body is ageing on a cellular level, which may differ from your chronological age. These tests measure key ageing biomarkers to reveal your true rate of ageing and help you take steps to improve your long-term health. Learn more about what biological age means and how PhenoAge works. Already got your results? Read our practical guide to actionable steps to improve your biological age.
Nine blood markers scored to estimate your biological age compared to your chronological age.
Measure NAD⁺ levels - the cellular energy molecule that declines with age and impacts repair and longevity.
Measure telomere length - a cellular ageing marker that reveals how fast your DNA is ageing compared to your actual age.
Want the most comprehensive insight into your long-term health and ageing?
For the most complete picture of your overall healthspan, our flagship longevity panels combine advanced biomarkers across metabolic, cardiovascular, hormonal and cellular ageing - the deepest view of how your body is functioning now.
250-biomarker longevity assessment mapping metabolic, cardiovascular, hormonal and cellular ageing across all key systems.
Our most comprehensive men's panel: cardiovascular, hormonal, nutritional and gut health plus 129-gene DNA insights in one test.
Our most comprehensive women's panel: cardiovascular, hormonal, nutritional and gut health plus 129-gene DNA insights in one test.
How well is your body methylating for long-term health?
Methylation plays a crucial role in detoxification, energy production, DNA repair and longevity. Poor methylation can accelerate ageing and increase the risk of chronic disease. These tests give insight into your methylation pathways and epigenetic ageing. Already tested? Read what to do next with your methylation results. For the full genetics story, see our DNA & genetic health testing.
Simple cheek swab testing 129 gene variants linked to detoxification, hormone balance and energy production. NATA accredited.
Follow-up to the Genetic Methylation Test: measures functional metabolic markers for detox, energy and nutrient processing.
Blood test for MTHFR C677T and A1298C gene variants linked to folate metabolism and elevated homocysteine.
Simple cheek swab for MTHFR C677T and A1298C gene variants - no blood draw required.
What does your DNA say about your long-term health risks?
Your genes provide insight into your predisposition for cardiovascular health, inflammation and other markers relevant to healthy ageing. Understanding these variants helps you take proactive steps with your practitioner. If your results point to cardiovascular markers, read our guide to reducing high cholesterol.
Screen 129 genes across digestion, hormones, athletic performance and longevity with a simple cheek swab. Australian NATA lab.
Combined DNA Comprehensive and Methylation tests covering 129 genes across metabolism, hormones, longevity and detoxification.
Identify your APOE gene variant to assess genetic cardiovascular and cognitive health risk.
Is chronic inflammation accelerating your ageing?
Chronic low-grade inflammation - sometimes called “inflammaging” - is one of the primary drivers of accelerated ageing and age-related disease. These panels measure inflammatory markers relevant to long-term health. Read our guide to how inflammaging accelerates ageing. For a deeper immune picture, see our immunity, allergy & inflammation testing.
Advanced 16-cytokine panel measuring immune signalling molecules linked to chronic inflammation and inflammaging.
Panel measuring CRP, IL-6 and homocysteine — markers commonly associated with inflammation.
Test for oxidised LDL — an advanced lipid marker increasingly included in cardiovascular assessments.
How is your heart health tracking as you age?
Cardiovascular health is one of the strongest predictors of healthy ageing. These tests assess arterial, lipid and metabolic markers relevant to heart health over time. For the full cardiovascular picture, see our heart & cardiovascular health testing.
A non-invasive CT scan that measures the amount of calcium (plaque) in your coronary arteries, producing a calcium score to discuss with your doctor.
Beyond basic cholesterol: measures ApoB, LDL particle size, lipoprotein(a) and 21 other advanced cardiac markers.
Multi-marker cardiovascular panel combining cholesterol, inflammation, homocysteine and metabolic markers.
Are your cellular energy levels declining with age?
Declining NAD+ levels and mitochondrial dysfunction play a major role in fatigue, inflammation and ageing. These tests measure cellular-energy and antioxidant markers. If low energy is your main concern, see our energy, fatigue & sleep testing.
Measure NAD⁺ levels - the cellular energy molecule that declines with age and impacts repair and longevity.
Coenzyme Q10 is an antioxidant produced by the body which is vital for cellular energy production. Low levels may suggest mitochondrial dysfunction, which can cause fatigue, muscle weakness, or neurological symptoms.
Glutathione is an essential antioxidant involved in protecting cells from oxidative damage, supporting detoxification processes, and contributing to immune system function.
Urine test measuring organic acid markers relevant to nutrient, gut and metabolic health.
