What Is TruDiagnostic?

TruDiagnostic is the world’s leading epigenetic testing laboratory, founded in Lexington, Kentucky. Since its launch, TruDiagnostic has pioneered consumer-accessible DNA methylation testing, making cutting-edge longevity science available to anyone who wants to understand how their body is truly ageing at a cellular level.

The TruDiagnostic laboratory holds both CLIA certification and CAP accreditation — the gold standard for clinical laboratory quality in the United States. Every sample processed by TruDiagnostic undergoes rigorous quality control, ensuring the data you receive is laboratory-grade and research-validated.

What sets TruDiagnostic apart from other biological age testing companies is the sheer depth of analysis. Each TruAge test examines over 900,000 CpG sites (specific locations on your DNA where methylation occurs), making it the most comprehensive epigenetic test available to consumers anywhere in the world. By comparison, most competing tests analyse fewer than 500,000 sites.

TruDiagnostic’s research has been validated in over 30 peer-reviewed scientific publications, and the company collaborates with leading universities and research institutions worldwide. Their testing methodology is used by prominent longevity figures including Bryan Johnson (the entrepreneur famous for his “Blueprint” age-reversal protocol), participants in the Rejuvenation Olympics, and longevity researchers across the globe.

What Your TruDiagnostic Results Reveal

When your TruAge report arrives, you will receive a detailed breakdown of multiple ageing and health indicators. Here is what each component means and why it matters:

Biological Age

Your biological age is the headline number — it represents how old your body actually is at a cellular level, regardless of your date of birth. A 45-year-old with a biological age of 38 is ageing more slowly than average, while a biological age of 52 would suggest accelerated ageing. TruDiagnostic calculates this using multiple validated epigenetic clocks, including the Horvath clock, Hannum clock, PhenoAge, and GrimAge.

DunedinPACE — Pace of Ageing

DunedinPACE is arguably the most actionable metric in the TruAge report. Developed by researchers at Duke University and the University of Otago, DunedinPACE measures your current rate of ageing — not a snapshot, but a speedometer. A score of 1.0 means you are ageing at the expected rate; below 1.0 means you are ageing slower than average; above 1.0 means faster. This is the metric used by Bryan Johnson, the Rejuvenation Olympics, and longevity researchers worldwide to track whether interventions are actually working.

SYMPHONYAge — 11 Organ Ages

SYMPHONYAge is a TruDiagnostic-exclusive algorithm that provides individual biological age estimates for 11 organ systems: brain, heart, liver, kidneys, lungs, immune system, inflammatory system, metabolic system, musculoskeletal system, hormone system, and blood. This allows you to see which organs are ageing faster or slower than others, helping you and your healthcare provider target interventions where they are most needed.

OMICmAge

OMICmAge is a next-generation epigenetic clock developed by TruDiagnostic that integrates DNA methylation data with blood biomarker predictions. It provides a more holistic ageing estimate than traditional single-clock approaches and has been shown to be a strong predictor of morbidity and mortality risk.

Telomere Length

Telomeres are protective caps at the ends of your chromosomes that shorten as you age. TruDiagnostic uses an epigenetic estimation of telomere length, which correlates with cellular ageing and chromosomal integrity. Shorter telomeres are associated with increased disease risk and cellular senescence.

Immune Cell Composition

Your TruAge report includes a detailed breakdown of your immune cell population, estimated from DNA methylation patterns. This includes proportions of CD4+ T cells, CD8+ T cells, natural killer cells, B cells, monocytes, and granulocytes. Shifts in immune cell composition are a hallmark of immunosenescence — the gradual deterioration of the immune system that comes with ageing.

Disease Risk Scores

TruDiagnostic provides epigenetic risk scores that flag elevated susceptibility to age-related conditions based on your DNA methylation patterns. These scores are not diagnostic, but they can highlight areas where preventive action may be beneficial and serve as early-warning signals worth discussing with your doctor.
