TruAge (TruDiagnostic)

Epigenetic

DNA Methylation Clocks

TruAge, from TruDiagnostic, is a commercially available epigenetic age test that combines multiple clock algorithms with immune cell deconvolution to report biological age. It is designed to be consumer-accessible and to aggregate several methylation-based measures into one panel. A longevity practice may use it as a convenient composite for tracking biological aging over time.

What It Measures

Commercial epigenetic age test combining multiple clock algorithms with immune cell deconvolution; consumer-accessible

Optimal vs. Lab Range

Longevity Optimal

Biological age < chronological age

Target range for optimal health and longevity based on research.

Standard Lab

N/A — compared to chronological age

Population-based reference range from standard labs.

Why It Matters

A TruAge biological age above chronological age reflects an accelerated aging composite, while a younger biological age is the goal. Its distinguishing feature is that it is a commercial composite bringing together several validated clock algorithms plus immune cell profiling in a single accessible report, rather than a single research clock like Horvath or a mortality-focused measure like GrimAge. This breadth can make results easier to obtain and follow, though the underlying algorithms carry the same emerging-science caveats. Interpreting it alongside individual clocks such as DunedinPACE and PhenoAge adds context. It is a research and consumer tool, not a diagnostic test.

How to Optimize

Because TruAge aggregates multiple clocks, a comprehensive longevity approach applies: consistent exercise, metabolic and nutritional optimization, quality sleep, and stress management form the foundation, and the immune-cell component underscores supporting overall immune and inflammatory health. Tracking results across repeat tests helps gauge trajectory. Investigational agents such as rapamycin and senolytics remain experimental and physician-directed. Biological-age testing is an emerging tool; interpretation and any interventions should be individualized with your physician; this content is educational and not a substitute for medical advice.

Buccal swab or whole blood (EDTA)

Patient prep

No fasting required. Maintain usual diet and medications unless advised.

Reporting unit

Confirm with the performing lab — units vary by region.

Pre-analytic notes

Standardize draw time of day, hydration, and recent exercise. Note any acute illness, supplements, or hormonal therapies on the requisition.

Recommended Follow-Up Actions

1
Confirm the result is reliable
Repeat abnormal values before acting — preferably from the same lab, same time of day, and under consistent prep. Rule out acute illness, recent intense exercise, or medication effects that can shift TruAge (TruDiagnostic).
2
Compare against optimal, not just lab range
Use the optimal window above as the target. Lab "normal" is built from the general population and often misses early dysfunction.
3
Pair with related markers
Order a complementary panel covering metabolic, inflammatory, and hormonal context to interpret this marker properly.
4
Discuss interventions with a clinician
Use the interpretation guidance above to frame the conversation. Bring trends, not just one datapoint, to your visit.
5
Re-test on a defined cadence
If a change is implemented, re-measure in 8–12 weeks for fast-moving markers, or 3–6 months for slower ones, to confirm response before escalating.
