BIOLOGICAL AGE TESTING

What Is Biological Age Testing?

Biological age testing estimates how your body is aging based on molecular markers linked to cellular, molecular, and systemic health. It reflects the state of key biological processes such as inflammation, immune activity, and metabolism.

Biological age can differ from chronological age and may change in response to lifestyle, health, and recovery, providing insight into the pace of biological aging.

MOLECULAR MARKERS OF AGING

How Biological Age Is Measured

Biological age is measured using molecular markers that change as the body ages. These markers reflect cellular, molecular, and systemic processes such as immune function, inflammation, and metabolic health, providing insight into how the body is aging over time rather than how many years have passed since birth.

Glycan-Based Biological Age Testing

Glycan-based testing measures patterns in glycans, which are complex sugar structures attached to proteins in the blood. These patterns reflect changes in the immune system and inflammation over time, both of which are closely linked to aging and long-term health.

Epigenetic (DNA Methylation) Tests

Epigenetic tests analyse DNA methylation, chemical tags that regulate how genes are expressed without changing the DNA sequence. Specific methylation patterns are strongly associated with aging and are used to estimate biological age at the molecular level.

Blood Biomarkers & Composite Scores

Some biological age estimates combine standard blood biomarkers such as C-reactive protein (CRP), cholesterol and lipid levels, glucose, and other metabolic markers. These composite scores reflect overall physiological health and the functioning of multiple body systems.

Who We Do Research With

What Accuracy Means

Biological age test accuracy refers to how reliably a test reflects biological processes associated with aging, and how consistently it produces similar results under the same conditions.

Validation vs Prediction

Validated tests, such as GlycanAge, are supported by research linking their markers to aging and health outcomes at a population level. This differs from predicting individual lifespan or disease, which is inherently uncertain.

Variability Over Time

Biological age can change due to lifestyle, illness, stress, or recovery. For this reason, trends across repeated tests are generally more informative than a single result.

BIOLOGICAL AGE INSIGHTS

What Biological Age Testing Can Tell You

Understanding Biological Aging

Biological age reflects how aging processes are unfolding within the body, based on biological signals associated with long-term health. It helps explain why aging can look different from one person to another.

BIOLOGICAL AGE EVIDENCE

Is Biological Age Testing Clinically Proven?

Biological age testing is based on molecular markers that have been widely studied in aging research. These markers are linked to long-term health outcomes and are evaluated across large population studies, providing scientific context for how biological aging is assessed.

Research-Backed Methods

Many biological age tests rely on biomarkers supported by peer-reviewed research. These biomarkers are consistently associated with aging processes and changes in long-term health risk.

Observational vs Interventional Evidence

Most biological age tests are validated using observational research, which examines how molecular markers are associated with aging and health outcomes over time. This type of evidence helps establish whether a marker reliably reflects biological aging.

Interventional studies, which test how biomarkers respond to specific changes or interventions, are less common and continue to evolve. Together, these approaches support the use of biological age testing as a tool for understanding and tracking biological aging over time.

Biological Age Testing with GlycanAge

GlycanAge is a biological age test that focuses on immune system aging by analysing glycans, complex sugar structures attached to proteins in the blood. These glycan patterns reflect long-term changes in inflammation and immune function, both of which are closely linked to aging.

The approach is research-led, grounded in glycoscience and peer-reviewed studies. GlycanAge is designed to provide a stable, biology-based measure of aging over time.
