Longevity
Biological age test
100+ biomarker estimates from a few drops of blood. Eleven organ-system ages, an overall epigenetic age, and your personalised written Health Map report.
You want to compare your estimated biological age with your age in years or with an earlier test. The Longevity Kit analyses chemical marks on your DNA, called methylation, in a small blood sample collected from your upper arm to estimate biological age and pace of ageing. You receive the laboratory report and a written Health Map that explains the estimates with your questionnaire answers and any other results you share. These estimates cannot predict your lifespan or diagnose disease.
What we measure
Eleven organ-system ages.
The TruAge + TruHealth measurement reads methylation patterns in your DNA to estimate the biological age of eleven distinct systems, plus your overall biological age, your pace of aging, and an estimate of telomere length.
Heart age
Brain age
Lung age
Kidney age
Liver age
Inflammation age
Metabolic age
Hormonal age
Immune age
Musculoskeletal age
Blood age
Overall biological age
GrimAge, PhenoAge, OMICmAge clocks.
Pace of aging
DunedinPACE, how many biological years per chronological year.
Telomere length
Methylation-derived estimate.
About the method
Blood sample collection at home
The kit uses a Tasso+ device on the upper arm, which collects capillary blood into a small tube. The tube goes to TruDiagnostic's laboratory in Kentucky for the methylation analysis.
A 2024 preprint co-authored by researchers at Harvard Medical School and TruDiagnostic reported that methylation-based proxies for clinical lab biomarkers identified deviations from reference ranges with about 90% accuracy. In 62% of the biomarkers studied, the proxies showed stronger statistical associations with disease outcomes than the observed lab values (Carreras-Gallo et al., medRxiv, 2024).
The paper is a preprint and has not yet been peer-reviewed. The authors describe these proxies as complementary to traditional biomarkers, not a replacement.

Results and written Health Map
Your personalised Health Map report is built from your questionnaire answers, existing results and email exchanges. Follow-up questions arrive by email or a further questionnaire when needed. You receive the final report in English, French or German within 3 working days of your answers to the last questionnaire.

What happens after the report is up to you. Most clients retest in 6 to 12 months (a second Kit, ordered when ready) to measure how the levers they pulled are moving their age. Some book Optimization sessions where the report points to a specific intervention, for example HRV biofeedback when cortisol pattern is dysregulated, or transcranial photobiomodulation when sleep and cognitive ages move together. Some take the report and run with it on their own.
