What Is Biological Age?
Your chronological age is simply the number of years since you were born. Your biological age, on the other hand, measures how old your body actually is at a cellular level. Two people born in the same year can have dramatically different biological ages — one might have the cells of someone ten years younger, while the other could be ageing far faster than the calendar suggests.
Biological age is determined by DNA methylation patterns — chemical markers that sit on top of your DNA and change as you age. These epigenetic modifications act as a molecular clock, reflecting the cumulative impact of your genetics, lifestyle, diet, sleep, stress, exercise, and environment on your body's ageing process. A biological age test reads these markers to calculate how old your body truly is.
The critical difference is this: unlike your birth date, biological age is modifiable. Research consistently shows that targeted lifestyle changes — improved nutrition, regular exercise, quality sleep, and stress management — can measurably reduce your biological age over time. An epigenetic age test gives you the baseline measurement you need to know where you stand, and a DNA methylation test is the gold standard method for obtaining that measurement.
This is why a biological age test has become essential for anyone serious about longevity. Without it, you are guessing. With it, you have a precise, science-backed number that tells you whether your health interventions are actually working.
The TruAge Test — Available at Lola Health
Lola Health is the UK's most affordable supplier of the TruAge COMPLETE test by TruDiagnostic — widely regarded as the most comprehensive biological age test in the world. While other consumer epigenetic tests analyse a fraction of your epigenome, TruAge COMPLETE examines over 900,000 CpG sites (DNA methylation markers), delivering an unmatched depth of insight into how your body is ageing.
When you order a biological age test from Lola Health, here is what your report will include:
- Biological age vs chronological age — your headline number. Are you ageing faster or slower than expected?
- DunedinPACE — your pace of ageing. This measures whether you are currently ageing faster or slower than one year per calendar year. It is the most actionable metric in the report.
- 11 organ-specific ages (SYMPHONYAge) — individual age estimates for your brain, heart, liver, lungs, kidneys, immune system, inflammatory system, metabolic system, hormone system, blood system, and musculoskeletal system.
- Disease risk scores — epigenetic risk indicators for major age-related conditions, based on validated methylation patterns.
- Telomere length estimation — telomere shortening is associated with cellular ageing and disease risk.
- Immune system composition — a breakdown of your immune cell types, revealing how well your immune system is functioning.
- Actionable insights — personalised guidance on lifestyle changes that could slow or reverse your biological ageing, based on your specific results.

Who Is This Biological Age Test For?
The TruAge biological age test is relevant to anyone who wants to understand how their body is ageing at a molecular level. In the UK, the test is particularly popular with the following groups:
The Science Behind Biological Age Testing
Biological age testing is grounded in the field of epigenetics — the study of how your behaviours and environment cause changes that affect the way your genes work. The specific mechanism measured by an epigenetic age test is DNA methylation: the addition or removal of methyl groups to cytosine bases in your DNA, particularly at CpG dinucleotide sites.
As you age, your DNA methylation patterns change in predictable ways. Scientists have developed mathematical models called epigenetic clocks that use these patterns to estimate biological age with remarkable accuracy. The most well-known clocks include:
Horvath Clock — the original epigenetic clock, published by Steve Horvath in 2013, measuring intrinsic ageing across multiple tissues.
GrimAge — a second-generation clock that predicts mortality and healthspan more accurately than first-generation clocks. Strongly associated with cardiovascular disease, cancer risk, and all-cause mortality.
DunedinPACE — developed by researchers at Duke University, this measures the pace of ageing rather than cumulative age. It answers: right now, how fast are you ageing per calendar year? This makes it the most responsive clock for tracking short-term lifestyle changes.
OMICmAge — TruDiagnostic's proprietary clock that integrates multi-omic data for the most accurate biological age prediction currently available.
The TruAge COMPLETE test includes all of these clocks and more, analysing over 900,000 CpG sites using the Illumina EPIC array. This is significantly more comprehensive than competing tests: most consumer biological age tests analyse fewer than 100,000 CpG sites, while clinical research typically uses the 850,000-site EPIC array that TruAge employs.
TruDiagnostic's Research Credentials
TruDiagnostic is not merely a consumer testing company. Their research has been validated in over 30 clinical trials, and their data has contributed to peer-reviewed publications in leading scientific journals. The TruAge platform is used by:

Frequently Asked Questions
What is a biological age test?
A biological age test measures how old your body is at a cellular and molecular level, as opposed to your chronological age (years since birth). It works by analysing DNA methylation patterns — chemical modifications on your DNA that change as you age. The result tells you whether your body is ageing faster or slower than expected. The TruAge biological age test available at Lola Health analyses over 900,000 DNA methylation markers, making it the most comprehensive consumer epigenetic age test available in the UK.
How accurate is the TruAge biological age test?
The TruAge test by TruDiagnostic is considered the gold standard in consumer biological age testing. It uses the Illumina EPIC array to analyse 900,000+ CpG sites and incorporates multiple validated epigenetic clocks including Horvath, GrimAge, DunedinPACE, and OMICmAge. The test has been validated across over 30 clinical trials and is used by leading longevity researchers worldwide. The margin of error for biological age estimation is typically within 1–2 years, and the DunedinPACE metric (pace of ageing) has been shown to be highly reproducible across repeat tests.
Can I buy a biological age test in the UK?

The kit is shipped directly to your home, you collect a simple finger-prick blood sample, and post it back using the prepaid return envelope. There is no need to visit a clinic or arrange international shipping. Lola Health is the most affordable supplier of the TruAge test in the UK at £380.
How much does a biological age test cost in the UK?
Prices for the TruAge COMPLETE biological age test in the UK range from £380 to £690 depending on the supplier. Lola Health offers the lowest UK price at £380 with free delivery. Epic Genetics charges £464, while Paar London charges £690. Ordering directly from TruDiagnostic in the US costs $499 plus international shipping and potential customs charges. All suppliers provide the identical test and report.
What is the best biological age test?
The TruAge COMPLETE by TruDiagnostic is widely considered the best biological age test available to consumers. It analyses over 900,000 CpG sites — more than any other consumer test — and includes multiple epigenetic clocks (Horvath, GrimAge, DunedinPACE, OMICmAge), 11 organ-specific ages via SYMPHONYAge, telomere length estimation, immune cell composition, and disease risk scores. It is the test used by Bryan Johnson, the Rejuvenation Olympics, and most longevity clinics worldwide.
How is biological age different from chronological age?
Chronological age is simply the number of years since you were born. Biological age measures how old your body actually is at a molecular level, based on DNA methylation patterns. Two people who are both 45 years old chronologically could have biological ages of 38 and 52 respectively, depending on their genetics, lifestyle, diet, exercise habits, sleep quality, and environmental exposures. Unlike chronological age, biological age can be improved through targeted interventions.
Can you reduce your biological age?
Yes. Research has demonstrated that biological age is modifiable. Interventions shown to reduce biological age include regular aerobic and resistance exercise, improved sleep quality and duration, a nutrient-dense diet (particularly Mediterranean and plant-rich diets), stress reduction practices, maintaining a healthy weight, and avoiding smoking and excessive alcohol. Some studies have shown biological age reductions of 3–5 years through comprehensive lifestyle programmes. The DunedinPACE metric in the TruAge test is particularly useful for tracking whether your interventions are slowing your pace of ageing.
What is DunedinPACE?
DunedinPACE (Pace of Aging Calculated from the Epigenome) is a DNA methylation measure developed by researchers at Duke University and the University of Otago. Unlike traditional epigenetic clocks that estimate cumulative biological age, DunedinPACE measures how fast you are currently ageing. A score of 1.0 means you are ageing at the expected rate of one biological year per calendar year. A score below 1.0 means you are ageing slower than average, while a score above 1.0 means you are ageing faster. It is considered the most responsive epigenetic metric for tracking the short-term impact of lifestyle changes, and it is the primary metric used by the Rejuvenation Olympics leaderboard.
How often should I test my biological age?
For most people, testing every 6–12 months provides a meaningful interval to detect changes in biological age and pace of ageing. If you are making significant lifestyle changes and want to track their impact, testing at baseline and then again after 6 months is recommended. Some biohackers and longevity enthusiasts test quarterly, though the DunedinPACE metric is typically more responsive to shorter-term changes than cumulative biological age estimates. Lola Health makes it easy to re-test, with the same £380 price and free UK delivery for each kit.
