The GlycanAge Test

The GlycanAge test is a biological age assessment tool, which measures age-related changes in glycans—complex carbohydrate molecules—attached to immunoglobulin G (IgG) antibodies. Glycans play critical roles in various cellular processes, including protein folding, cell signaling, and immune responses. The test analyzes the glycosylation patterns of IgG, as these patterns are known to change with age and are influenced by genetics, lifestyle, and environmental factors.

By examining specific glycan structures on IgG molecules, the GlycanAge test provides an estimation of an individual's biological age, which may differ from their chronological age. This information can offer insights into one's health status and aging process, potentially guiding lifestyle adjustments to promote healthier aging. The GlycanAge test established relationships between glycosylation patterns and biological aging.

GlycanAge — Immune & Biological Age

What it is

GlycanAge measures patterns of sugar molecules on antibodies (IgG glycans) that reflect immune aging and systemic inflammation.

It returns an estimated “GlycanAge” based on a blood sample.

Why it matters

GlycanAge tracks immune-system aging and can change relatively quickly with interventions. It’s useful for monitoring inflammation-related aging and treatment response.

Our results

Jun 2024 — GlycanAge: 70 → 40 (30 year deceleration);

May 2025 — maintained 40 (−31 years deceleration).

How to use it

Test before and after interventions (3–12 months) to see immune-aging changes; combine with epigenetic and CRP data for context.

Test Results:

The GlycanAge Test result by GlycanAge.com for Mr. Steven M Schorr on June 2024 shows reduction of the biomarker of aging by 30 years from 70 to 40. In May of 2025, Mr. Schorr's GlycanAge continues at 40, with the age deceleration increasing to 31 years.

GlycanAge Science

GlycanAge™ analyzes the glycans attached to your Immunoglobulin G (IgG) antibodies. These glycans are powerful biomarkers that reflect your body's state of health and aging.

Using the GlycanAge test biomarker can assess the efficacy of the Extended Longevity Protocol. It provides a scientific basis for tracking how lifestyle interventions influence biological aging.
