TruDiagnostic TruAge Epigenetic Test Review and Pricing

The Short Answer on TruAge Legitimacy

TruAge is a legitimate CLIA certified laboratory test that measures deoxyribonucleic acid (DNA) methylation patterns to estimate biological aging rates. The test is worth buying for individuals tracking trends across repeat tests, but it provides limited value as a one-off assessment. TruDiagnostic charges $499 for a single test kit.

The laboratory operates under CLIA standards to verify analytical testing processes. On its provider page, TruDiagnostic states that TruAge is not a diagnostic test. TruDiagnostic positions the report as an adjunct to clinical evaluations.

The consumer TruAge product page states that no prescription or medical diagnosis is required to take the test. TruDiagnostic notes in its provider documentation that DNA methylation biomarker outputs should not be used as the sole basis for treatment decisions.

A 2026 study in Aging Cell by Sehgal and colleagues evaluated 18 epigenetic clocks. The researchers reported that biological reliability between separate blood draws was substantially lower than technical reproducibility. TruDiagnostic's FAQ says many customers retest every 3 to 6 months to track progress.

What the TruAge Test Measures

The TruAge test analyzes 1,000,000+ DNA methylation sites to generate 75+ epigenetic biomarker scores. TruDiagnostic reports these outputs from a blood sample collected at home. The epigenetic clock guide details how published mathematical algorithms convert methylation data into age predictions.

TruDiagnostic reports an overall biological age score called OMICmAge, which TruDiagnostic states was developed with Harvard. The test also reports DunedinPACE, an algorithm developed by researchers at Duke University and Columbia University. TruDiagnostic says DunedinPACE gives biological years elapsed per calendar year.

Organ-specific aging is reported through SYMPHONYAge, which TruDiagnostic attributes to Yale University research on 11 organ systems. The report includes surrogate estimates for C-reactive protein (CRP) and interleukin-6 (IL-6). None of the TruDiagnostic documentation states that the kit physically measures blood CRP or tests physical grip strength.

These functional outputs represent epigenetic correlations calculated from methylation patterns. The report also includes scores for telomere length, immune cell proportions, and lifestyle exposures.

TruAge Price and Every TruDiagnostic Kit

A single TruAge test costs $499 on the official TruDiagnostic shop. TruDiagnostic also sells an annual subscription for $998 billed upfront. That subscription includes 4 tests and renews annually.

On the subscription plan, the arithmetic comes to $249.50 per test. That rate represents a 50% reduction compared to purchasing 4 individual tests at list price. TruDiagnostic states on its product page that TruAge qualifies for Health Savings Account (HSA) and Flexible Spending Account (FSA) reimbursement.

TruDiagnostic sells other testing options on its online storefront. The TruHealth test costs $499 and reports over 105 markers across 19 biological systems. The TruAge and TruHealth combination kit costs $849 for 180 epigenetic biomarkers.

A previous product URL for TruAge PACE returned a 404 error at the time of writing. TruAge PACE is not listed on the TruDiagnostic shop. Healthcare provider pricing remains private inside the active provider portal.

TruAge Sample Collection and Turnaround Times

The TruAge test uses a finger-prick blood sample collected at home and returned by mail to TruDiagnostic's laboratory in Kentucky. TruDiagnostic's site footer lists 881 Corporate Dr., Lexington, Kentucky. TruDiagnostic operates under CLIA certification.

On the TruDiagnostic About page, TruDiagnostic names Dr. Melissa Keinath, a board-certified laboratory geneticist, as its laboratory director. TruDiagnostic describes itself as a CLIA-certified DNA methylation diagnostics company and one of the largest epigenetic testing laboratories globally. None of the TruDiagnostic pages reviewed state College of American Pathologists (CAP) accreditation.

Sample collection requires a few drops of blood from a finger-prick. On the TruDiagnostic provider page, TruDiagnostic states collection takes approximately 3 minutes. Users mail the collection card back in a prepaid United States Postal Service (USPS) envelope.

Turnaround times differ slightly across TruDiagnostic's pages. The consumer product page states results arrive within 3 to 4 weeks after the laboratory receives the sample. The provider page states that results arrive within 2 to 4 weeks.

Accuracy Findings and Epigenetic Clock Reliability

Independent peer-reviewed studies report high technical reproducibility for replicate assays but substantially lower biological reliability across repeat blood samples from the same person. TruDiagnostic states on its consumer page that TruAge achieves 98% test-retest reproducibility. Its provider documentation reports an average intraclass correlation coefficient (ICC) exceeding 0.98 for the same blood sample run twice.

In 2022, Belsky and colleagues published the DunedinPACE algorithm in eLife. The algorithm tracks within-person decline across 19 organ integrity indicators over 2 decades, using 173 cytosine-phosphate-guanine (CpG) methylation sites. Test-retest ICC reached 0.96 in 36 replicate 450k blood samples and 0.97 in 28 EPIC replicate samples.

In 2022, Higgins-Chen and colleagues reported in Nature Aging that technical noise causes deviations up to 9 years between replicates for 6 prominent clocks. Their principal-component clock modifications brought most replicates within 1.5 years of each other. That investigation did not test the commercial TruAge kit directly.

TruDiagnostic's 98% reproducibility figure comes from running the same sample twice. A 2026 study of 18 clocks by Sehgal and colleagues in Aging Cell found that technical reproducibility did not predict biological reliability across repeated measures. The measures were collected within short intervals under varying conditions. The authors observed that biological reliability was substantially lower across intervals.

The same team's preprint reported that PCGrimAge was the only clock with an ICC above 0.75 for biological reliability. The number a customer sees on a retest carries both technical noise and biological variation. In the Berlin Aging Study II (BASE-II), Vetter and colleagues evaluated 14 aging biomarkers across 1,083 older adults over 7.4 years.

DunedinPACE showed the strongest and most consistent association with mortality in adjusted models. Hand grip strength and IL-6 also predicted mortality. In those models, CRP did not predict mortality. The CRP levels guide covers what a CRP result measures.

Retest Frequency and Biological Tracking Intervals

TruDiagnostic does not require customers to retest every 3 months. On its product FAQ, TruDiagnostic notes that many customers choose to retest every 3 to 6 months to track biological trends. That customer pattern forms the basis for the 4-test annual subscription.

The annual plan lowers the individual test cost from $499.00 to $249.50. The biological age reduction guide explains how dietary shifts and sleep changes influence epigenetic markers over months.

In 2026, Sehgal and colleagues published a meta-analysis in Nature Medicine reviewing 51 interventional trials across 16 clocks. The authors concluded that clocks trained to predict mortality or pace of aging show the strongest responses across all interventions.

Clock Development and Commercial Research Disclosures

Academic institutions developed the aging algorithms TruDiagnostic reports, with several published studies disclosing commercial ties. DunedinPACE was built from the Dunedin Study 1972-1973 birth cohort. TruDiagnostic credits it to Duke University with Columbia University. In their eLife paper, the DunedinPACE authors disclosed an invention licensed to an unnamed commercial entity.

In 2026, Chen, Dwaraka, and colleagues published OMICmAge in Nature Aging. The model was built from routine clinical laboratory data across roughly 31,000 Mass General Brigham Biobank participants and validated in cohorts including 14,213 TruDiagnostic samples. The authors reported that OMICmAge performs comparably or better than existing biological markers.

The competing interests disclosure in Nature Aging states that the work was conducted under a sponsored research agreement between Brigham and Women's Hospital and TruDiagnostic. Several study authors are TruDiagnostic employees. The disclosure notes that TruDiagnostic generated the DNA methylation and proteomic data for the study.

In 2025, Sehgal and colleagues published the Systems Age model in Nature Aging, calculating 11 physiological system scores from a single blood draw. A 2026 Nature Medicine paper discloses that 2 authors co-invented SystemsAge and received consulting fees from TruDiagnostic.

TruDiagnostic's materials list SYMPHONYAge without stating whether it matches the SystemsAge code. The biological age guide explains what a biological age number means.

Data Storage and Privacy Policy Terms

TruDiagnostic states in its official privacy policy that it will not share individual-level epigenetic or self-reported information with third parties without explicit consent. TruDiagnostic stores test results using encryption protocols and access controls. Customers may opt into research programs using de-identified biological data.

According to the TruDiagnostic privacy policy, users can withdraw research consent at any time inside their account settings. Withdrawing consent does not reverse data previously published or used in completed studies.

Who TruAge Fits and Who Can Skip It

The TruAge test fits individuals seeking to monitor long-term pace of aging across repeat tests, but it is not intended for medical diagnosis. TruDiagnostic states that its outputs should not serve as the sole foundation for treatment decisions. People looking for diagnostic medical screening should skip TruAge and consult a licensed physician.

A single $499 test provides limited insight because biological reliability fluctuates across separate draws. Individuals who will not retest should also pass on the kit. Lower-cost alternatives exist using standard clinical blood chemistry. The wearable age comparison examines how non-invasive fitness metrics track physiological conditioning.

In 2018, Liu and colleagues published the Phenotypic Age model in PLOS Medicine. The algorithm calculates biological age from chronological age and 9 routine clinical chemistry markers. In 11,432 adults from the National Health and Nutrition Examination Survey (NHANES), Phenotypic Age was associated with all-cause mortality after adjusting for age and sex.

The authors noted that further evaluation in other cohorts remains necessary. A price reduction on single kits or clear clinical trial evidence linking algorithm changes to disease prevention would alter this assessment.

The biological age test guide compares additional testing methods and commercial platforms. Start with the routine markers on the biological age blood test page before you pay for an epigenetic test.
