TruAge Test
TruAge Test
TruAge by TruDiagnostic is an at-home epigenetic test that shows how your body is ageing at a cellular level. TruDiagnostic's CLIA-certified US laboratory reads over 900,000 DNA methylation markers from a finger-prick sample and turns them into your biological age (OMICm Age), your pace of ageing (DunedinPACE) and the age of eleven body systems, with fitness, telomere, immune-cell and lifestyle-exposure estimates alongside.
Your report is written by Lola. Your measurements are placed among people of your age and sex in the laboratory's reference cohort and explained in plain English, with a reading guide, general lifestyle guidance and a retest plan, so your next sample tells you which way you are moving. It arrives as a PDF by email and lives in the Lola app.
Lola is the official partner of TruDiagnostic, bringing the pace-of-ageing test (the DunedinPACE method) to the UK and Europe. This is the same test used by Bryan Johnson, Peter Attia and leading longevity researchers, and Lola is the official route to access it in the UK and Europe.
This is a wellness service, not a medical device. The report is an epigenetic ageing readout and is not intended for the diagnosis, prevention, prediction, prognosis, monitoring or treatment of disease, and it does not include a doctor review. Your sample and its methylation data are genetic and health data: processed on your explicit consent, never sold, deleted on request. See our Wellness Disclaimer and Privacy Policy.
Frequently Asked Questions
What does the TruAge test measure?
The TruAge test analyses over 900,000 DNA methylation markers. Your report leads with three figures - OMICm Age, overall systems age and pace of ageing (DunedinPACE) - followed by eleven body-system ages and methylation-based estimates for fitness, telomere length, immune cells, and smoking and alcohol exposure. Unlike wellness panels that measure fluctuating daily metrics, this test reflects how your body is ageing at a molecular level.
How is biological age different from chronological age?
Chronological age is how many years you have lived. Biological age estimates how old your body appears at a cellular level, based on DNA methylation patterns. Two people born the same year can have very different biological-age readings depending on lifestyle, genetics and environmental factors.
How accurate is the test?
TruAge uses validated epigenetic-clock algorithms based on peer-reviewed research. The test is most informative for adults aged 20-70. Results represent a snapshot influenced by recent lifestyle factors and are best used as a wellness tracking and motivational tool alongside regular wellness testing.
What sample is needed?
The test uses a finger-prick collection kit you do at home. There is no clinic appointment, no phlebotomist booking, and no fasting required. The collection itself takes about 5 minutes. Results typically take 3-4 weeks from the day TruDiagnostic's CLIA-certified US lab receives your sample.
Can lifestyle influence my biological-age readout?
Research suggests that exercise, quality sleep, stress management, a Mediterranean-style diet, not smoking, and moderate alcohol consumption are associated with shifts in biological-age readings over time.
How often should I retest?
Every 6-12 months. Epigenetic changes occur gradually, so retesting more frequently than every 6 months is unlikely to show meaningful change. This interval allows time for lifestyle factors to register.
