How to Choose a Longevity Clinic: 12 Questions to Ask | YEARS

How to Choose a Longevity Clinic

You have heard of longevity medicine. You know that prevention requires more than a standard annual blood test at your general practitioner. Perhaps you already have two or three clinics on your shortlist, with prices ranging from €1,500 to €17,000. But how do you decide? How do you choose a longevity clinic that is medically sound before you book?

The market is growing rapidly. Alongside established preventive medicine centers, dozens of new practices are emerging, varying drastically in quality and diagnostic depth. The spectrum ranges from clinically led, high-performance diagnostics to lifestyle wellness programs lacking a true medical core. What is at stake is not just a significant financial investment, but your opportunity for genuine early detection.

This article provides you with 12 concrete questions to help you test the substance behind the marketing promises.

Questions 1–3: How to Evaluate Medical Substance

The foundation of any serious longevity clinic is its diagnostic depth. Marketing terms like "comprehensive" or "holistic" are meaningless without verifiable facts.

1. Which medical specialties are represented?

A single individual cannot cover the entire spectrum of modern preventive medicine. The human body is an interconnected system, and analyzing it requires interdisciplinary expertise.

Ask specifically about the team: Are board-certified specialists in internal medicine, cardiology, radiology, sports medicine, and neurology involved? Or is a single general practitioner with an additional certificate overseeing the entire program? A reputable longevity clinic transparently lists its medical team and their qualifications on its website. If this information is missing, consider it a first warning sign.

2. What diagnostic methods are used, and how deep do they go?

The difference between a standard check-up and true longevity diagnostics lies in the details. Do not just ask if something is measured, but what and how.

• Blood panel: How many biomarkers are analyzed? A standard check-up often includes only a limited number of routine laboratory values. Comprehensive programs like YEARS Core® analyze 87 or more biomarkers. Important additional markers can include ApoB and Lp(a) for cardiovascular risk, fasting insulin alongside glucose for assessing metabolic health and calculating HOMA-IR, and hs-CRP as an inflammatory marker.
• Pulmonary diagnostics: Is a simple spirometry performed, or a body plethysmography? The latter measures not only lung volume but also airway resistance, providing a significantly more precise picture of lung function.
• Cardiovascular diagnostics: Does it only include an ECG, or does it also feature an echocardiogram, a measurement of arterial stiffness, and an HRV (heart rate variability) test?
• Performance diagnostics: Is your maximum oxygen uptake (VO₂max) measured via ergospirometry? Cardiorespiratory fitness is a strong predictor of long-term mortality risk. In a large 2022 cohort, each 1-MET higher exercise capacity was associated with approximately 14% lower all-cause mortality risk (Kokkinos et al., JACC 2022).
• Imaging: Targeted ultrasound of organs and vessels is a good standard. A whole-body MRI can reveal structural abnormalities and offers a deeper anatomical analysis, but it should always be embedded in an overall diagnostic concept.

3. Is the program individualized or a standard package?

A good diagnostic program is standardized to allow for comparisons over time, but it must offer room for individualization. A 35-year-old competitive athlete has different risk factors than a 55-year-old executive with a family history of cancer.

Ask directly: "What information do you need from me before the appointment to adapt the program?" A detailed medical history questionnaire or a preliminary medical consultation are signs of quality. Programs that operate without prior knowledge of your personal history are usually standardized mass processing.

Questions 4–6: Medical Quality and Evidence-Based Practice

Expensive equipment does not automatically equal good medicine. The most critical service is the medical interpretation of your data.

4. What are the qualifications of the lead doctors?

Look past the marketing titles. "Longevity Expert" is not a protected term. Ask for concrete qualifications:

• Board certification: Have they completed specialized medical training (Facharzt), ideally in internal medicine, cardiology, or a related clinical field?
• Clinical experience: Where did the doctors work previously? University hospitals and research institutions are strong indicators of quality.
• Scientific background: Are there publications in recognized peer-reviewed journals, verifiable via PubMed?

A weekend certificate in "anti-aging medicine" cannot replace years of clinical practice.

5. How are findings explained and followed up?

A diagnostic day that ends with a stack of laboratory printouts is virtually useless. The true value is created through synthesis and contextualization.

• Medical report: Will you receive a structured written report that explains the findings in context, visualizes relevant data, and clearly outlines recommended next steps?
• Strategy consultation: Is there a personal consultation with a doctor to discuss the results, and if so, when? A conversation immediately at the end of the diagnostic day can be incomplete because laboratory and imaging results may still be pending. A dedicated consultation after all relevant results are available allows for a more comprehensive interpretation.
• Point of contact: Who is available to answer your questions after the consultation?

6. Does the clinic work evidence-based and communicate transparently?

Longevity medicine operates at the intersection of established prevention and new, experimental approaches. A clinic's integrity is shown by how it communicates this boundary.

• Sources: Are claims about the efficacy of tests or therapies backed by references to scientific studies?
• Guidelines: Do the protocols align with the guidelines of medical societies, such as the AHA, ESC, or national internal medicine boards?
• Transparency regarding limitations: Does the clinic openly communicate the limits of its tests? A good clinic explains that epigenetic clocks "provide an estimate" of biological age, rather than "measuring it exactly." They will point out that a liquid biopsy "complements" classic cancer screening, but does not "replace" it. Claims like "We find every cancer" are unprofessional and simply false.

Questions 7–9: Prevention, Costs, and Long-Term Care

A top-tier longevity clinic invests in your health literacy, not just in a one-off diagnostic event.

7. Is the focus on prevention or selling therapies?

Longevity medicine is primarily preventive. Its goal is to identify risks early enough so you can counteract them through lifestyle changes or targeted interventions before a disease develops.

Be skeptical if you are immediately sold expensive IV drips, supplement packages, or hormone therapies during your first visit. A serious clinic first conducts comprehensive diagnostics, discusses the results, and then proposes a prioritized action plan. This plan may also include recommendations for referrals to external specialists, rather than trying to treat everything in-house.

8. How transparent are the costs and services?

Prices for longevity programs vary widely. A basic check-up starts around €1,500, while programs including genomics and advanced imaging can cost up to €17,000. Transparency here is not a given.

• Total price: Is the communicated price the final price, or are there additional costs for the laboratory, doctor's consultation, or reports?
• Scope of services: Are all included services detailed in writing? Instead of "comprehensive lab," it should state: "87 biomarkers, incl. ApoB, Lp(a), HOMA-index, ...".
• Billing: In Germany, are physician services billed according to the official medical fee schedule (GOÄ)? This provides the standard billing framework for privately insured patients, although reimbursement ultimately depends on medical necessity and the individual insurance tariff.

9. Is there long-term support and follow-up?

A single diagnostic day provides a baseline. The real value emerges longitudinally, through repeated measurements over years.

• Annual updates: Does the clinic offer standardized re-checks to make progress measurable?
• Coaching: Is there support for implementing the recommendations, such as nutrition, training, or sleep coaching?
• Medical check-ins: Are there doctor consultations distributed throughout the year to adjust the course?

A premium offering like YEARS Evolve® or YEARS Ultimate® clearly distinguishes between the initial deep diagnostics and the ongoing support programs.

Questions 10–12: Incidental Findings, Technology, and Reputation

The final three questions target the core of medical responsibility and a clinic's technological maturity.

10. How are incidental findings handled?

This is perhaps the most important question of all. With comprehensive diagnostics like a whole-body MRI, incidental findings are common in asymptomatic individuals, and some may require additional investigation. Reported prevalence varies substantially depending on the imaging protocol and how clinically relevant findings are defined.

A good clinic is prepared for this.

• Protocols: Is there a clear protocol for handling incidental findings?
• Communication: How and when is such a finding communicated?
• Referrals: Is there an established network of specialists for rapid referrals?
• False-positive rates: Does the clinic speak openly about false-positive results—for example, with a liquid biopsy—and the associated stress of follow-up examinations? A clinic that addresses this proactively shows clinical strength.

11. What technologies are used for longevity measurements and how are they contextualized?

The longevity market is full of hype. Asking critical questions is mandatory.

• Biological age: How is it determined? Beware of providers who claim to "measure it exactly." Reputable clinics speak of an "estimate" or a "profile," based on a combination of markers. This can include epigenetic clocks as well as functional tests such as VO₂max, HRV, bone density, and neurocognitive tests. A meta-analysis showed that a five-year increase in epigenetic age was associated with an 8 to 15% higher mortality risk, while also emphasizing the ongoing need for research (Fransquet et al., Clin Epigenetics 2019).
• Biobanking/Cryopreservation: Does the clinic offer the option to store blood, urine, or stool samples for future analysis? This enables longitudinal comparisons with technologies that may not even be available today.

12. Are there independent reviews, references, or scientific collaborations?

Reputation is more than polished testimonials on a website.

• Scientific connection: Are there collaborations with universities or research institutions?
• Medical team: Are the doctors' qualifications verifiable through external sources like PubMed, hospital websites, or LinkedIn?

What Defines a Serious Longevity Clinic

A serious longevity clinic is not a wellness oasis. It is a data-driven, medically led preventive institution. The elegant ambiance and marketing are secondary. What truly matters is the clinical depth of the diagnostics, the qualifications of the doctors, and the structure of the follow-up care. Invest the time to ask these 12 questions.

Frequently Asked Questions (FAQ)

How much does a longevity clinic cost?

Costs vary significantly. Evidence-based initial diagnostic programs start at around €1,500 to €3,500. Programs that include whole-body MRI, liquid biopsy, or genomics typically range between €7,000 and €17,000. Annual follow-up and support programs cost an additional €2,500 to €6,000 per year.

What is the difference between a longevity clinic and a classic health check?

A classic health check, such as the statutory "Check-up 35" in Germany, focuses on established screening measures for major common diseases using a limited number of standard markers. A longevity clinic typically uses a significantly greater depth of biomarkers, advanced imaging, and functional tests to characterize established risk factors and detect selected abnormalities before they become symptomatic.

Which biomarkers should a serious longevity clinic measure at a minimum?

Beyond a standard blood count, a high-quality longevity panel should include the following values:

• Cardiovascular: ApoB, Lp(a), hs-CRP
• Metabolic: Fasting glucose and fasting insulin, allowing calculation of HOMA-IR where clinically useful
• Vitamins & Trace Elements: Vitamin D3, ferritin
• Fatty Acids: Omega-3 index

These markers can provide additional information beyond total cholesterol and blood glucose when interpreted in the appropriate clinical context.

Does private health insurance cover the costs of a longevity clinic?

Partially. Reputable clinics in Germany bill physician services according to the official medical fee schedule (GOÄ). Some medically indicated services may be reimbursed by private health insurance depending on the individual tariff and medical necessity. Purely preventive measures without a medical indication are less frequently reimbursed. It is advisable to clarify this in advance with the clinic and your insurance provider.
