Biological Age

GlycanAge Immune Age Testing

GlycanAge is an IgG-glycan-derived estimate associated with age and inflammatory states. It describes one emerging biomarker, not aging as a whole.

The Science

What This Test Measures

GlycanAge analyzes the glycan patterns attached to your IgG antibodies. Population studies have found associations between these patterns, chronological age, and inflammatory conditions, but association does not establish a validated clinical decision tool for an individual.

The assay differs from epigenetic clocks because it measures IgG glycan features rather than DNA methylation. Hormonal state, illness, medications, and other biological variation may affect the estimate and complicate comparisons over time.

Research on IgG glycans may help describe relationships among aging, immunity, and inflammation. It does not show that changing this score improves health or identify a specific intervention.

Interpretation

What the Report May Describe

✓

An immune-age estimate derived from IgG glycan patterns

✓

The balance of glycan features associated with inflammation

✓

How the estimate compares with a reference population

✓

Potential context from hormones, illness, and chronic disease

✓

Why this marker differs from an epigenetic clock

✓

Where evidence is still emerging rather than settled

Reading the Evidence

How to Think About It

01

Understand the marker

The assay measures patterns on IgG antibodies; it does not measure every biological process associated with aging.

02

Check the clinical question

Ask whether an immune-aging estimate will change a specific decision or simply add another score to track.

03

Expect biological variation

Inflammation, hormones, illness, medication, and other context can influence glycan patterns and interpretation.

04

Avoid chasing the score

A change matters most when it aligns with validated health measures and a sustainable intervention—not the number alone.

Is This Right For You?

Who This Is For

•

You're evaluating an emerging IgG glycan biomarker with realistic expectations

•

You understand that an association with age does not predict your outcome

•

You want to compare this estimate with validated clinical measures

•

You can account for illness, hormones, medication, and other changing context

•

You will not use a score change as proof that an intervention worked

•

You understand that evidence for clinical decision-making remains unsettled

GlycanAge is neither a diagnosis nor a comprehensive measure of biological age. Its clinical utility, treatment guidance, and individual outcome prediction remain uncertain.
