TruAge COMPLETE vs TruAge PACE: Which Biological Age Test Should You Buy?

TruDiagnostic offers two main epigenetic age tests -- TruAge COMPLETE and TruAge PACE -- and choosing between them is one of the most common questions in the biological age testing space. This guide breaks down exactly what each test measures, what reports you receive, how much they cost, and which one you should buy based on your goals.

Epigenetic age testing analyses methylation patterns at CpG sites on your DNA to estimate how old your body truly is -- regardless of what your birth certificate says. A 45-year-old with a biological age of 38 is ageing slower than average. A 45-year-old with a biological age of 52 has some work to do.

But TruDiagnostic's two flagship products -- TruAge COMPLETE and TruAge PACE -- serve fundamentally different purposes. Buying the wrong one means either overspending or getting less data than you need. This guide ensures you make the right choice.

TruAge COMPLETE: The Full-Spectrum Biological Age Test

Price: GBP 380 at Lola Health | Results: 2-3 weeks

TruAge COMPLETE is the most comprehensive epigenetic age test available to consumers. It analyses over 900,000 CpG sites using the Illumina EPIC methylation array chip -- the same technology used in cutting-edge ageing research at institutions like Harvard, Yale, and Duke University.

With that volume of data, the COMPLETE test generates an extraordinary breadth of reports. This is not a single number. It is a full biological audit of your body.

What TruAge COMPLETE Reports Include

• Overall biological age -- Your headline number. How old is your body compared to your chronological age?
• DunedinPACE (pace of ageing) -- Developed at Duke University, this measures how fast you are ageing per year. A score of 1.0 means you are ageing at the expected rate. Below 1.0 is slower than average. Above 1.0 is faster. This is arguably the most actionable metric in the report because it reflects your current rate of ageing, not cumulative damage.
• SYMPHONYAge (11 organ-specific ages) -- This is where COMPLETE truly differentiates itself. SYMPHONYAge breaks your biological age into 11 organ systems: brain, heart, liver, lung, kidney, hormone, metabolic, musculoskeletal, blood, inflammation, and immune. You might discover your heart is ageing faster than the rest of your body while your liver is ageing slower -- invaluable for targeting interventions.
• OMICmAge -- Harvard's most predictive epigenetic ageing algorithm. It integrates multi-omic data to produce a biological age estimate that correlates strongly with morbidity and mortality outcomes.
• Telomere length -- The protective caps on chromosome ends. Shorter telomeres are associated with cellular ageing and increased disease risk.
• Immune cell deconvolution -- A breakdown of your immune cell populations including T-cells, B-cells, natural killer cells, and macrophages. This reveals whether immunosenescence (immune ageing) is occurring prematurely.
• Disease risk scores -- Epigenetic risk assessments for type 2 diabetes, cardiovascular disease, and certain cancers based on methylation patterns from large population studies.
• Smoking and alcohol epigenetic impact -- Your DNA methylation carries a chemical record of tobacco and alcohol exposure, even years after stopping. These reports quantify the residual impact on your ageing.
• Fitness and inflammation levels -- Epigenetic markers of physical fitness and systemic inflammation, showing how your lifestyle registers at the molecular level.

Who Should Buy TruAge COMPLETE?

COMPLETE is the right choice if this is your first biological age test. You need the full baseline. Without organ-specific ages, disease risk scores, and immune cell data, you have no way of knowing which systems to prioritise. The DunedinPACE score alone -- while valuable -- tells you how fast you are ageing but not where the problems are.

Think of COMPLETE as the full health MOT. You would not skip your first annual blood test and jump straight to monitoring a single biomarker. The same logic applies here.

TruAge PACE: The Focused Follow-Up Test

Price: $229 / approximately GBP 185 | Results: 2-3 weeks

TruAge PACE is a streamlined test designed for one purpose: measuring your pace of ageing over time. It analyses fewer CpG sites than COMPLETE and generates a narrower set of reports.

What TruAge PACE Reports Include

• DunedinPACE (pace of ageing) -- The same Duke University-developed metric included in COMPLETE. Your ageing speedometer: are you ageing faster or slower than 1.0 years per calendar year?
• Telomere length -- Chromosomal cap length as a secondary ageing marker.

What TruAge PACE Does NOT Include

• Overall biological age
• SYMPHONYAge organ-specific ages (brain, heart, liver, etc.)
• OMICmAge (Harvard's predictive algorithm)
• Immune cell deconvolution
• Disease risk scores
• Smoking and alcohol impact scores
• Fitness and inflammation markers

Who Should Buy TruAge PACE?

PACE is the right choice if you have already completed a COMPLETE test and want to track whether your interventions are working. Changed your diet? Started a new supplement protocol? Began strength training? PACE tells you whether your pace of ageing has improved without the cost of a full retest. At roughly half the price, it makes frequent monitoring financially viable.

TruAge COMPLETE vs PACE: Side-by-Side Comparison

Which TruAge Test Should You Buy? A Decision Guide

The right test depends entirely on where you are in your biological age testing journey. Here are the four most common scenarios:

Scenario 1: This Is Your First Biological Age Test

Buy: TruAge COMPLETE

If you have never tested your biological age, you need the full picture. COMPLETE gives you a detailed baseline: overall biological age, which organs are ageing faster or slower, pace of ageing, immune composition, disease risks, and the epigenetic impact of past exposures. You cannot optimise what you have not measured.

Scenario 2: You Have Already Done COMPLETE and Want to Track Progress

Buy: TruAge PACE

You have your baseline. Now you want to know whether changes to diet, exercise, supplements, or sleep are actually working. DunedinPACE is the most sensitive metric for detecting short-term shifts in your rate of ageing. At roughly half the cost of COMPLETE, PACE makes regular monitoring financially sustainable.

Scenario 3: You Are Budget Conscious

Buy: TruAge COMPLETE first, then switch to PACE for follow-ups

It might seem tempting to start with the cheaper PACE test, but this is a false economy. PACE tells you how fast you are ageing but not where the problems are. Without organ-specific ages and disease risk scores, you have no way to prioritise your interventions. Save up for COMPLETE as your first test, then use PACE for subsequent monitoring at the lower price point.

Scenario 4: You Are a Serious Longevity Enthusiast

Buy: COMPLETE every 12 months, PACE every 3-6 months between

This is the gold-standard testing cadence. An annual COMPLETE gives you a thorough yearly check-in on all organ systems, disease risks, and immune function. PACE tests every 3-6 months in between track whether new protocols or lifestyle shifts are moving the needle. A typical year: COMPLETE in January, PACE in April, PACE in July, PACE in October, then COMPLETE again the following January.

Also Worth Knowing: TruHealth ($499)

TruDiagnostic also offers TruHealth, which is a fundamentally different type of test. TruHealth is not an epigenetic test. It is a functional biomarker panel that measures over 105 blood-based markers covering metabolic health, hormones, inflammation, organ function, and nutrient status.

While TruAge tells you how old your body is at the epigenetic level, TruHealth tells you how well your body is functioning right now through traditional biomarker measurement. For those who want both perspectives, Lola Health offers a TruAge COMPLETE + TruHealth bundle at GBP 600 -- a meaningful saving compared to purchasing separately. This combination gives you the most complete picture available: epigenetic age data plus functional biomarker data in a single testing cycle.

Frequently Asked Questions

What is the difference between TruAge COMPLETE and PACE?

TruAge COMPLETE analyses over 900,000 CpG sites and provides 15+ reports: overall biological age, 11 organ-specific ages, DunedinPACE, OMICmAge, telomere length, immune cell analysis, disease risk scores, and lifestyle impact metrics. TruAge PACE provides only two reports: DunedinPACE and telomere length. COMPLETE costs GBP 380 at Lola Health; PACE costs approximately GBP 185. COMPLETE is for wide-ranging baseline testing; PACE is for affordable follow-up monitoring.

How often should I take the TruAge test?

For most people, an annual TruAge COMPLETE test is sufficient for a full biological age assessment. If you are actively making lifestyle changes and want to track their impact more frequently, adding a TruAge PACE test every 3-6 months between annual COMPLETE tests is the recommended approach. Epigenetic changes take time to manifest, so testing more frequently than every 3 months is unlikely to show meaningful differences.

Can I start with PACE instead of COMPLETE?

You can, but it is not recommended. PACE only tells you your pace of ageing and telomere length. Without the full baseline from COMPLETE -- including organ-specific ages, disease risk scores, and immune cell analysis -- you have no context for interpreting your PACE score and no way to identify which body systems need the most attention. Starting with COMPLETE and then using PACE for follow-ups is a far more effective strategy.

What is the cheapest way to track biological age?

The most cost-effective approach is to take TruAge COMPLETE once as your baseline (GBP 380 at Lola Health), then use TruAge PACE (approximately GBP 185) for all subsequent monitoring. This gives you a complete starting point followed by affordable ongoing tracking. Over the course of a year with one COMPLETE and two PACE tests, you would spend roughly GBP 750 for three data points -- significantly less than three COMPLETE tests at GBP 1,140.

Where can I buy TruAge in the UK?
