Do you feel your age? Biological age testing looks beyond the date on your birth certificate
to find out how your body is ageing at a cellular level. We determine this by measuring
specific biomarkers linked to ageing, inflammation, and long-term health risk.
Not only will this give you your biological age, but it will also give you a more complete picture of your current health.
We then work with you to develop a plan to achieve your goals going forward.
Discover Your True Age with GrimAge
HealthScreen is proud to offer exclusive access to GrimAge in Australia, the world’s leading biological age testing technology. Unlike your chronological age, your biological age reveals how your body is ageing on a cellular level. Using advanced epigenetic testing, GrimAge analyses DNA methylation markers (chemical changes to your DNA that occur over time) to provide a detailed picture of your health, ageing rate, and long-term disease risk.
At HealthScreen, our medical experts combine these insights with comprehensive health assessments to provide recommendations on what you can do to live a longer, healthier life.

What is biological age testing?
Biological age testing provides a deeper understanding of how your body is ageing on a cellular level. Your biological age reflects the health and function of your cells, tissues, and organs. These are all influenced by your genetics, lifestyle, diet, and exercise.
By analysing DNA methylation patterns through advanced epigenetic testing, we can estimate how fast or slow your body is truly ageing, providing a more accurate measure of health and risk for age-related disease.

GrimAge sets the standard for biological age testing
Through our exclusive partnership with GrimAge, we’ve brought this cutting-edge technology to Australia, giving our clients access to the most advanced and scientifically validated method for measuring how their body is truly ageing on a cellular level.
Developed by the Horvath Lab at UCLA, GrimAge is the gold standard in biological age testing, analysing DNA methylation markers (chemical changes to your DNA that occur over time) due to ageing and lifestyle factors. Extensive research shows GrimAge consistently outperforms all other epigenetic clocks in predicting age-related disease, mortality, and overall healthspan.
GrimAge incorporates eight methylation-based protein markers linked to ageing and inflammation, including:
- Plasminogen activation inhibitor 1 (PAI-1)
- Cystatin C
- Leptin
- Tissue inhibitor metalloproteinases 1 (TIMP1)
- Adrenomedullin (ADM)
- Beta-2-microglobulin (B2M)
- Growth differentiation factor 15 (GDF15)
Please note that GrimAge also includes self-reported smoking history to improve accuracy.
The Science Behind GrimAge
GrimAge was developed using large population-based biobanks and validated across multiple independent studies and tissue types. Its predictive power has been documented in leading scientific journals:
- Lu AT, et al. Aging (Albany NY). 2019.
- McCrory C, et al. The Journals of Gerontology: Series A, 2021.

FAQs
What is the difference between biological and chronological age?
Biological age measures the health of your cells and how quickly your body is aging, while chronological age is the actual number of years you’ve lived.
How accurate is biological age testing?
At HealthScreen, we use the peer-reviewed GrimAge technique, developed by the Horvath Lab at UCLA. This scientifically validated method is considered more accurate than earlier biological age tests because it analyses specific DNA methylation markers shown to closely reflect biological ageing and age-related health risk.
Your results will help you understand how your body is ageing compared to your chronological age and support more informed, preventative health planning with your doctor.
How often should I have my biological age tested?
It’s recommended to undergo testing annually or as part of a longevity program to track progress and make adjustments.
Is the test invasive?
The process is simple and typically requires a blood sample, collected during your HealthScreen appointment.
What type of sample is required for the test?
The test is a simple blood test. We will collect this during your appointment.
How long does it take to receive results?
You should get your results within six to eight weeks once the laboratory analysis is complete. This comprehensive report will outline your biological age, alongside recommendations on what you may be able to do to improve biological age.
How can I use my results to improve my biological age?
At HealthScreen, our medical experts combine these insights with comprehensive health assessments to provide recommendations on what you can do to live a longer, healthier life.
Can lifestyle changes impact my biological age?
Absolutely. Lifestyle factors are a significant part of biological ageing. Physical activity, nutrition, sleep, and stress are all known to influence how the body ages over time. For many people, results can help inform changes, big or small, that support preventative health.
