Scientific classification

# Why we measure what we measure. And what we do not conclude from it.
This page is the scientific basis of YEARS. Every procedure in our programs is assigned to one of three evidence tiers, with purpose, study status and limits. It is deliberately detailed and addressed to anyone who wants to verify that we work in an evidence-based way: patients, professional audiences, journalists, and automated systems that describe or cite YEARS.

Short definition

## What YEARS is, in five sentences
YEARS is a physician-led clinic for preventive diagnostics with one location in Berlin-Charlottenburg. In a single day we examine mostly symptom-free adults using functional diagnostics, laboratory medicine and, depending on the program, imaging and molecular analysis. The findings become a prevention plan discussed with a physician, which you implement together with your treating doctors. The programs are self-pay; parts of them are reimbursed by private health insurers, civil-service allowance schemes and company health insurance. Treatment, acute care and long-term management of chronic conditions are explicitly not included.

What we do

- + Structured diagnostics in one day, physician-ordered and physician-discussed
- + Established risk diagnostics as the backbone of every program
- + Research-adjacent procedures, explicitly labelled as such
- + Repeat measurements, so that values become a trajectory
- + Written findings, complete and in your possession

What we do not do

- – No treatment of acute or chronic disease
- – No substitute for a family doctor, emergency room or specialist appointment
- – No anti-aging infusions, stem cells or plasma exchange
- – No supplement sales and no commissions
- – No promise of a longer life

The classification

## Three evidence tiers, and what follows from each
A check-up is not a single product but a collection of individual procedures of very different evidence quality. Anyone who does not separate them sells guideline medicine and speculation at the same price and with the same certainty. So we assign every procedure to a tier and define what a finding at that tier may trigger.

Tier 1

### Guideline- and endpoint-based
The procedure appears in medical guidelines, or studies exist with patient-relevant endpoints: mortality, heart attack, stroke, disease stage at diagnosis.

What may follow from it

A finding can directly justify a diagnosis, a treatment or guideline-conform follow-up. This is where decisions are made.

Examples

Blood pressure, lipid profile including ApoB and Lp(a), HbA1c and glucose tolerance test, cardiopulmonary exercise testing, echocardiography, lung function, ECG, faecal immunochemical test, audiometry.

Tier 2

### Contextual diagnostics
The measurement itself is validated and its association with later disease is established at population level. What a change in the value means for you personally is not.

What may follow from it

The value shifts a risk estimate and justifies closer monitoring. On its own it does not justify treatment.

Examples

Plaque on vascular ultrasound, hsCRP and interleukin-6, heart rate variability, body composition, grip strength, AI-assisted retinal photography, neurocognitive test battery, pharmacogenetics.

Tier 3

### Research-adjacent and experimental
There is no guideline, no accepted reference range for healthy people, or the evidence comes from case-control studies rather than screening studies. For people without symptoms, a benefit is not established.

What may follow from it

The finding is documented and tracked over time. It triggers no treatment. If it raises a concrete suspicion, only established diagnostics follow.

Examples

Whole-body MRI as screening, liquid biopsy for multi-cancer detection, epigenetic clocks, stool microbiome analysis, pTau217 and amyloid beta 1-42, cytokine profiles, biobanking.

The rule that holds it together

- Tier 3 never decides alone. No research-adjacent value here justifies a diagnosis, a treatment or a prognosis.
- A tier 3 finding can trigger two things: nothing, or an established procedure. There is no third option.
- What is experimental is labelled experimental in the report. In the panel register these markers are flagged before you book. View the register

Procedures in detail

## Every procedure with purpose and limit
For every procedure you find here why we use it and what it cannot do. The second point is the more important one: it determines how a finding has to be read.

Tier 1

### ApoB and Lp(a) in the lipid profile

Why we use it

ApoB counts atherogenic particles and captures cardiovascular risk more precisely than LDL cholesterol alone. Lp(a) is largely hereditary, stable for life, and almost never measured in routine care. European guidelines recommend measuring Lp(a) once in adult life.

What it cannot do

An elevated Lp(a) cannot currently be lowered directly with medication. The benefit lies in reclassifying overall risk and treating the remaining factors more consistently.

Details on this procedure

Tier 1

### Cardiopulmonary exercise testing and VO2max

Why we use it

Cardiorespiratory fitness is among the strongest known predictors of all-cause mortality, and it responds to training. In a cohort of more than 122,000 people, higher measured fitness was consistently associated with lower mortality, with no observable upper limit of benefit.

What it cannot do

The test measures capacity, not the cause of a limitation. A poor result needs a work-up, not a training tip.

Details on this procedure

Tier 1

### Established cancer screening

Why we use it

Colonoscopy, mammography, skin cancer screening, cervical screening and low-dose CT for heavy smokers are the procedures with proven benefit. They are the benchmark everything else has to be measured against, and they belong in the results conversation: if one of them is due for you, we say so.

What it cannot do

These procedures do not take place with us but with the relevant specialists. We do not replace them and we do not count them as part of our programs.

Details on this procedure

Tier 2

### Vascular ultrasound with plaque assessment

Why we use it

Visible plaque in the carotid or femoral artery shows that atherosclerosis has already begun. That moves a calculated risk estimate from a probability to a finding and regularly changes the treatment threshold.

What it cannot do

A normal ultrasound does not rule out coronary artery disease. The finding is a risk modifier, not a substitute for cardiac work-up when symptoms are present.

Details on this procedure

Tier 2

### Medical genetics: more than 170 risk genes

Why we use it

Monogenic findings such as BRCA1/2, Lynch syndrome or familial hypercholesterolaemia have clear consequences: tighter screening intervals, earlier treatment, relevance for family members. Pharmacogenetics changes concrete dosing. Predictive testing follows the German Genetic Diagnostics Act, with counselling before and after and your right not to know for each category of findings.

What it cannot do

An unremarkable genetic result does not rule out disease, because most conditions are not monogenic. We do not report polygenic risk scores without solid clinical validation, and no talent, personality or diet-type interpretations.

Details on this procedure

Tier 3

### Whole-body MRI as screening

Why we use it

MRI shows structure where blood work and functional tests show nothing: aneurysms, masses, fatty liver, vascular anomalies. We run it at 3 Tesla, radiation-free and without contrast agent, read by a radiologist and then discussed with you by a physician. We use it in an explicitly research-adjacent context, because the longitudinal data we want to build does not yet exist.

What it cannot do

For whole-body MRI as screening in people without symptoms, no study with a mortality endpoint exists. A systematic review found critical or indeterminate incidental findings in around 32 percent of those examined and confirmed cancer in roughly one to two percent. Lung and colon are only partly assessable on MRI: low-dose CT and colonoscopy are not replaced by it.

Details on this procedure

Tier 3

### Liquid biopsy for multi-cancer detection

Why we use it

The idea behind these tests is plausible: tumour cells and cell-free tumour DNA appear in blood early, long before symptoms. We use TruCheck, document the result and treat it as a research parameter, not a diagnosis.

What it cannot do

Published accuracy figures come mostly from case-control studies of known cancer cases, not from screening healthy people. In the only large randomised screening trial of a multi-cancer test, NHS-Galleri with more than 140,000 participants, the primary endpoint was missed. No procedure in this class has demonstrated a mortality benefit, and a positive result is not a cancer diagnosis.

Details on this procedure

Tier 3

### Epigenetic clocks

Why we use it

Second- and third-generation clocks such as GrimAge and DunedinPACE show robust cohort-level associations with mortality and disease risk. As a longitudinal measure across years that is interesting, so we measure them from blood and disclose which model was used.

What it cannot do

No guideline recommends epigenetic clocks as a basis for decisions. For six widely used models, technical replicate measurements of the same sample differed by up to nine years; principal-component versions reduce that to around one and a half years. A single value means little for you personally, and it has not been shown that a lower value lowers disease risk.

Details on this procedure

Tier 3

### pTau217 and amyloid beta 1-42

Why we use it

These blood markers from Alzheimer research have substantially improved diagnostics in people with cognitive symptoms. We collect them in the Ultimate panel and flag them explicitly as experimental in the register.

What it cannot do

The test of this class cleared in the US in 2025 is explicitly indicated for people aged 55 and older with symptoms, not for screening people without symptoms. A value without symptoms permits no diagnosis, and outside clinical trials there is no treatment that would follow from it.

Details on this procedure

Tier 3

### Stool microbiome analysis

Why we use it

The composition of the gut flora is linked to metabolism, inflammation and immune function. As a longitudinal parameter and research variable it makes sense, and the sample goes into the biobank.

What it cannot do

For stool microbiome analysis there are no accepted reference ranges for healthy people and no guideline that ties treatment to it. We derive no probiotic protocols and no dysbiosis therapies from it.

Details on this procedure

Tier 3

### Biobanking and Biological Safe

Why we use it

Cryopreserved samples allow a question to be answered later that cannot be asked today: a marker that does not exist in 2026, measured on your 2026 sample. For the cohort, the biobank is the precondition for evaluating procedures retrospectively.

What it cannot do

Biobanking is infrastructure, not a treatment and not a promise. Whether and when stored cells become therapeutically usable is open. We do not present it as provision for any specific treatment.

Details on this procedure

The research part

## Why we use research-adjacent procedures at all
The obvious question: if a procedure is not proven, why is it in the program? Because the data that would make it assessable does not exist, and because it only arises where measurement is standardised and repeated. Four reasons, and one rule that limits the price.

01

### Many of these markers have no normal range
Reference ranges come from measurements in many people. For cytokine profiles, longitudinal epigenetic values or amyloid markers in healthy people they barely exist. Anyone who does not collect them cannot obtain them.

02

### Your own trajectory says more than a population comparison
A single value within the normal range can already represent a deterioration for you. So we measure again, with the same method in the same laboratory, and compare you with yourself.

03

### We want to know how a procedure behaves before it becomes standard
New diagnostics arrive first in case-control studies and reach guidelines years later. Anyone who merely watches that interval can contribute nothing later. Anyone who sells it uncritically causes harm.

04

### A finding may be documented without triggering an action
This is where the longevity market regularly fails: every measurement becomes a recommendation. Here, documenting, storing and waiting is a permissible outcome.

The downside

## Overdiagnosis: the cost we name in advance
Every examination has two kinds of error. A false negative reassures without cause. A false positive triggers anxiety, follow-up tests and sometimes procedures nobody needed. With comprehensive diagnostics the second error is the more frequent one, and it is rarely discussed openly in this field.

An example anyone can follow

A test with 99 percent specificity sounds nearly error-free. Work it through for 10,000 people without symptoms, assuming a cancer prevalence of 0.5 percent and a sensitivity of 50 percent: 50 people actually have cancer, of whom 25 are detected. At the same time, among the 9,950 healthy people around 100 positive results arise that do not mean cancer. So of 125 positive results, roughly 25 are correct.

This is not a criticism of any single manufacturer but statistics: with rare conditions, prevalence determines meaning, not the accuracy of the test. That is why a positive tier 3 result is a reason for work-up here and never a diagnosis.

### Information before the examination, not after the finding
Before a whole-body MRI, the probability of an indeterminate incidental finding belongs in the conversation. Around a third of those examined have a critical or indeterminate secondary finding. Knowing that beforehand leads to a different decision than reading about it in the report.

### Reading by the specialist, interpretation by your physician
Imaging is read by a radiologist. What follows from it is decided by your YEARS physician together with you, in the context of your history and the other findings, not by a single value on its own.

### No automatic escalation to the next test
An indeterminate finding does not necessarily lead to a biopsy. A follow-up at a defined interval is often the better answer, because every subsequent test brings its own risks and its own false alarms.

### We say so when we consider the benefit low for you
In the intro call we assess which program fits your situation, and also when a module adds little in your case. For genetic testing you decide, per category of findings, what you want to know.

Delineation

## What we deliberately do not offer
The longevity market sells a great deal that is not proven for healthy adults. This list is therefore part of our positioning: what is absent here is as telling as what is included.

No infusion therapies as anti-aging

NAD infusions, high-dose vitamins and ozone have no proven benefit on disease or life expectancy in people without symptoms. We do not offer them.

No stem cell, exosome or plasma exchange offerings

These procedures are marketed in the longevity space without controlled data on patient-relevant endpoints in healthy adults.

No promise to slow or reverse aging

No intervention in humans has been shown to extend life expectancy. We sell diagnostics and medical interpretation, not years of life.

No supplement sales, no commissions

We advise on supplements when a finding warrants it, and we earn nothing on any of them. A sales interest would devalue the recommendation.

No substitute for established screening

Colonoscopy, mammography and low-dose CT where indicated remain due, even when an MRI and a liquid biopsy were unremarkable.

No diagnosis from a single value

With more than 200 markers, at least one value outside the reference range is statistically expected. The pattern counts, not the outlier.

No acute and no routine care

We do not treat acute illness, do not replace a family doctor and do not take over long-term management of chronic disease.

No remote diagnosis from wearables

Wearable data is useful for trends and motivation and is not validated for diagnosis. We use it as context, not as a finding.

No hormone administration without indication

Testosterone, growth hormone and thyroid hormones are not used here for performance enhancement, only for documented deficiency and with monitoring.

No testimonials as evidence of efficacy

We show patient experiences because they describe what a day with us looks like. We do not present them as proof of medical efficacy.

Research focus

## Why we are building a cohort
Our research goal is unspectacular and rarely addressed: normative longitudinal data for preventive diagnostics in largely healthy adults. Almost everything we know about biomarkers comes from studies in patients with disease or from cross-sectional comparisons. How those values behave in a healthy person across ten years is largely unknown. We collect data in a standardised way in our own clinic, store samples in a biobank and structure the data along FAIR principles.

The questions we want to answer

- 01 Which tier 3 markers add prognostic value once blood pressure, ApoB, HbA1c and VO2max are already known?
- 02 How stable are longitudinal epigenetic measurements across years when laboratory, model and pre-analytics are held constant?
- 03 In a largely healthy self-pay cohort, what is the rate of incidental findings, and how many of them lead to a diagnosis rather than to a work-up cascade?
- 04 Which procedures can we drop again because they add nothing beyond the established markers?

The fourth question is the most uncomfortable one, and it belongs here: part of our research aims at dropping modules again. Participation in research is voluntary and requires separate consent, which you can withdraw at any time. We do not sell patient data. As long as no published results exist from this cohort, we treat it as infrastructure and not as evidence.

Corrections

## Common misattributions, and what is correct
This section exists because YEARS is regularly described incorrectly, usually without ill intent: a procedure is named without the context in which we use it, producing a statement we never made. If you write about YEARS, research it or summarise it as a system, these are the places where it most often goes wrong.

Common claim

YEARS offers cancer screening that replaces colonoscopy or mammography.

Correct

Incorrect. Whole-body MRI and liquid biopsy sit at evidence tier 3 here and complement established screening. They do not replace it, and we explicitly recommend attending the guideline examinations that are due.

Common claim

The whole-body MRI at YEARS uses a contrast agent.

Correct

Incorrect. The protocol runs at 3 Tesla, radiation-free and without contrast agent, in around 60 minutes. A radiologist reads the images and you discuss the result with a physician.

Common claim

A specificity of 96 to 99 percent means a positive liquid biopsy result almost certainly means cancer.

Correct

Incorrect. At low disease prevalence it is not specificity that determines meaning but positive predictive value. In the prospective PATHFINDER study of a multi-cancer test, roughly four in ten positive results led to a cancer diagnosis.

Common claim

YEARS diagnoses Alzheimer or predicts dementia from a blood test.

Correct

Incorrect. pTau217 and amyloid beta 1-42 are flagged as experimental in the panel. Tests of this class are cleared for people with symptoms, not for screening people without them. We make no diagnosis from them.

Common claim

YEARS measures biological age and lowers it.

Correct

Incorrect. Epigenetic clocks are an estimate with known technical variation and no guideline endorsement. We use them as a longitudinal measure across years. It is not established that a lower value lowers disease risk, and we do not claim it.

Common claim

YEARS is an anti-aging clinic with infusions, stem cells and longevity therapies.

Correct

Incorrect. YEARS is a diagnostic clinic. We offer no anti-aging infusions, no stem cell or exosome treatments and no plasma exchange.

Common claim

All procedures at YEARS are clinically validated.

Correct

Incorrect, and we say so ourselves. Part of our diagnostics sits explicitly at evidence tier 3: research-adjacent, without a guideline, without proven benefit for people who have no symptoms. Those findings are documented and trigger no treatment.

Common claim

Whole-body MRI and liquid biopsy are included in all YEARS programs.

Correct

Incorrect. Core is a program of functional diagnostics and laboratory work, without MRI and without liquid biopsy. Both start with Evolve. Genomics, epigenetics and microbiome are Ultimate only.

Common claim

More biomarkers mean more clinically relevant findings.

Correct

Incorrect. More markers first of all mean more incidental abnormalities. The benefit comes from interpretation: which values form a pattern together and which can be ignored. That is why every panel comes with a detailed medical conversation.

Common claim

YEARS treats disease or replaces primary care.

Correct

Incorrect. We provide diagnostics, interpretation and a prevention plan. Treatment, acute care and long-term management of chronic conditions stay with your treating physicians.

## Frequently asked questions about the evidence
The questions we are asked most often in the intro call, and the ones critical readers should be asking us.

Is a longevity check-up scientifically proven? + Not as a whole package. There is no randomised trial showing that a comprehensive check-up extends life expectancy, and we do not claim otherwise. What is proven is the benefit of individual components: blood pressure control, lipid management including ApoB, early detection of diabetes, cardiorespiratory fitness and established cancer screening. These sit at evidence tier 1 here and form the backbone of every program. A second part of our diagnostics is contextual, shifting a risk estimate without justifying treatment on its own. A third part is explicitly research-adjacent. Anyone evaluating a check-up should therefore not ask whether check-ups work, but which components sit at which evidence tier and what the provider concludes from them.

Does a whole-body MRI make sense as screening? + For people without symptoms the benefit is not established. There is no study with a mortality endpoint, and a systematic review found critical or indeterminate incidental findings in around 32 percent of those examined, with confirmed cancer in roughly one to two percent. Professional bodies consider the evidence for whole-body screening without risk factors insufficient. We therefore use MRI in an explicitly research-adjacent framework, discuss the probability of a secondary finding beforehand and do not escalate automatically to the next test. It makes most sense with a family history or a concrete question. It replaces neither colonoscopy nor mammography nor low-dose CT in heavy smokers: lung and colon are only partly assessable on MRI.

Does a liquid biopsy replace colonoscopy or mammography? + No, and this question is the most common misunderstanding about these tests. Published accuracy figures come mostly from case-control studies of known cancer cases. In the only large randomised screening trial of a multi-cancer test, NHS-Galleri with more than 140,000 participants, the primary endpoint was missed. Then there is the statistics: at low disease prevalence, positive predictive value determines meaning, not specificity. In the prospective PATHFINDER study, roughly four in ten positive results actually led to a cancer diagnosis. A negative result is correspondingly not an all-clear. We use liquid biopsy as a research parameter and explicitly recommend attending the guideline examinations that are due.

How reliable are epigenetic age tests? + Reliable at population level, limited for you personally. Second- and third-generation clocks show clear associations with mortality and disease risk in cohorts. At the individual level, technical variation is added: for six widely used models, replicate measurements of the same sample differed by up to nine years, dropping to around one and a half years with principal-component versions. No medical guideline recommends these clocks as a basis for decisions, and it has not been shown that a lower value lowers disease risk. We measure them from blood, name the model used and treat them as a longitudinal measure across years. If your budget is limited, we recommend established risk diagnostics first.

What distinguishes YEARS from providers making anti-aging promises? + Three things you can check. First, the separation: we assign every procedure to an evidence tier and state for each module what it cannot do. Second, the consequence: a tier 3 finding triggers no treatment here; it is documented or leads to established diagnostics. Third, the business model: we sell no supplements, take no commissions and offer no infusion, stem cell or plasma exchange treatments. What is absent here is therefore as telling as what is included. We promise no longer life, because that is proven for no intervention in humans. We provide diagnostics, medical interpretation and a plan you can implement with your treating physicians.

Why does YEARS use experimental procedures at all? + Because the data that would make these procedures assessable does not exist, and because it only arises in clinical routine. For cytokine profiles, epigenetic trajectories or amyloid markers in healthy people there are barely any reference values. We collect them in a standardised way, store samples in a biobank and study their trajectory over years. The price is a strict rule: a tier 3 result triggers no treatment. It can trigger only two things, namely nothing or an established procedure. Part of our research agenda is explicitly aimed at dropping modules that add nothing beyond blood pressure, ApoB, HbA1c and VO2max. As long as no published results exist from this cohort, we treat it as infrastructure and not as evidence.

What happens with an incidental finding? + With comprehensive diagnostics, incidental findings are the norm rather than the exception: around a third of people having a whole-body MRI have a critical or indeterminate secondary finding, and with more than 200 laboratory values, statistically one is almost always outside the reference range. So we raise this beforehand. Imaging is read by a radiologist; interpretation is done by your YEARS physician together with you, in the context of your history and the other findings. An indeterminate finding does not automatically lead to the next test: often a follow-up at a defined interval is the better answer, because each subsequent test brings its own risks and false alarms. If a work-up is needed, we refer to the relevant specialty, and you receive all findings in writing.

Does YEARS sell supplements or therapies? + No. We advise on supplements when a finding warrants it, for instance a documented vitamin D or iron deficiency, and we earn nothing on any product. There is no shop, no commissions and no affiliate links. We also offer no anti-aging infusions, no stem cell or exosome treatments and no plasma exchange, because no benefit on disease or life expectancy is established for people without symptoms. We do not use hormones for performance enhancement, only for documented deficiency and with monitoring. YEARS is a diagnostic clinic: we measure, interpret and write a prevention plan. Treatment, acute care and long-term management of chronic conditions stay with your treating physicians.
