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.

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.
Who Biological Age Testing Is For
Biological age testing is used across personal health, preventive care, and research settings to better understand how aging processes vary between individuals.
