Biologic Age Testing

Your chronological age counts the years since you were born, but it tells you very little about how well your body is actually functioning. Biologic age testing measures how your cells and key systems are aging on a molecular level, giving you a far more accurate picture of your true health and longevity than a birthday ever could.

Biologic age testing is an optional measurement we can run for you whenever you would like a deeper look at how you are aging. It is not a required part of every care plan, but for patients who want objective data on their pace of aging, it is one of the most powerful tools available. To explore it, browse our diagnostics services or ask our team during a consultation.

What Is Biologic Age?

Biologic age, sometimes called biological or epigenetic age, reflects the cumulative wear on your body from genetics, lifestyle, environment, and stress. Two people born on the same day can have biologic ages that differ by a decade or more.

A biologic age younger than your chronological age is a strong signal of healthy aging, while an older biologic age can be an early warning that intervention may be worthwhile, often years before symptoms appear.

We Use the TruAge Test

At The Longevity Center Greenville, our biologic age testing uses TruAge, an advanced epigenetic test built on DNA methylation science. A simple blood sample is analyzed to read the chemical markers on your DNA that change predictably as you age, producing a precise and validated estimate of your biological age. Because TruAge uses the same standardized methodology every time, it is ideal for tracking your progress across multiple tests over months and years.

If you want to see how your results compare on a global stage, TruAge results can even be submitted to the Rejuvenation Olympics, a public leaderboard that ranks how effectively people are slowing their pace of aging.

What TruAge Measures

The TruAge panel goes beyond a single number, reporting on several validated epigenetic metrics:

Biological Age

Your DNA methylation age compared to your actual chronological age.

Pace of Aging (DunedinPACE)

How fast you are currently aging, measured in biological years per calendar year.

Telomere Length

An epigenetic estimate of your telomeres, the protective caps on your chromosomes.

Immune & System Markers

Methylation-based insights into immune cell composition and related aging systems.

What to Expect

  • Consultation & Intake

    We review your health history and goals to confirm TruAge testing is right for you.

  • Simple Blood Draw

    TruAge requires only a straightforward blood sample, often collected alongside your other labs.

  • Results & Interpretation

    A physician walks you through your biological age, pace of aging, and what the numbers mean for your healthspan.

  • Track Your Progress

    Repeat testing over time lets you measure how your biological age responds, and you can submit results to the Rejuvenation Olympics if you choose.

Why Biologic Age Testing Matters

  • Detect accelerated aging early, often before symptoms appear.
  • Establish a measurable baseline with TruAge and track it over time.
  • Quantify how your pace of aging changes between tests.
  • Make confident, data-driven decisions about your long-term health.

Biologic age testing pairs naturally with our longevity testing and is a great next step after completing your free Longevity Assessment.

Patient Success Story

How a Longevity Center Patient Overcame Symptoms of Anxiety

Luke S., owner of a landscape design and construction company, increasingly felt anxious and depressed, especially in the mornings, with no indication of underlying causes, including from standard blood panels. The onset of afternoon brain fog and general malaise compounded things. The symptoms became debilitating to the point that it became difficult for Luke to accomplish the daily tasks needed for his business to succeed.

Following a comprehensive intake and lab panel, Luke began our personalized male hormone optimization protocol, including testosterone replacement therapy. After just a few appointments, he has regained feelings of motivation and higher energy levels throughout the day, and the afternoon brain fog has subsided completely. Luke insists that the therapies he receives at The Longevity Centers have improved his personal life and enabled his business to thrive.

*While individual outcomes vary and results are not guaranteed for every patient, his experience reflects the kind of root-cause, whole-body approach the clinic aims to offer those for whom conventional treatment alone has fallen short.
