Biological Age (composite)

Bio Age

An estimated biological age based on a composite of your panel results.

What is it

Biological Age (composite) — in plain English.

Biological age is a composite estimate derived from multiple biomarkers in your full panel. It estimates how your physiology compares to population norms for your chronologic age.

Why it's measured

What Bio Age can reveal.

Biological age has been studied in research as a more integrated measure of health than chronologic age alone.

Reference range

Where most laboratories draw the standard line.

Standard laboratory reference

Computed from panel years

Reference ranges vary by laboratory. Your individual reference range will appear on your test report and should be interpreted by your physician in the context of your overall health profile.

What results may indicate

Higher vs. lower Bio Age — at a high level.

Elevated

A biological age above your chronologic age has been studied in research as a marker of accelerated aging.

Lower

A biological age below your chronologic age has been studied in research as a favorable marker.

These associations are general. They are not a personal diagnosis or prediction. Discuss your individual results with your physician in the context of your full health profile.

When it's measured

Biological age is a composite estimate derived from multiple biomarkers in your full panel. It estimates how your physiology compares to population norms for your chronologic age.

Why is Biological Age (composite) measured?

It's one of the markers used to build a fuller picture of your health. On its own it tells you very little, so it's most informative when reviewed alongside related markers.

How is Biological Age (composite) tested?

It's measured from a standard blood draw at Quest or LabCorp. Biological Age (composite) is one of the markers included in the OPTML Apex Panel, where your results are read across systems and reviewed by a U.S.-licensed physician.

What should I do with my Biological Age (composite) result?

Reference ranges vary by laboratory, and a single value rarely tells the whole story. Review your result with a physician in the context of your other markers, symptoms, and history.
