What to Ask a Longevity Clinic Before You Pay

Longevity medicine has arrived in Athens in the same form it arrived everywhere else: a comprehensive panel of biomarkers, an imaging package, a wearable, a report, and a subscription. Some of it is genuine preventive medicine practised by people with the training to interpret it. Some of it is a blood draw and a PDF.

We are not going to name clinics in this piece. Health is the one category on this site where a name published without verified credentials would be actively dangerous rather than merely embarrassing, and verification takes longer than an article. What we can do is give you the questions that reliably separate the two, because they are the same questions everywhere and almost nobody asks them.

One: who interprets the results, and what are they trained in?

A panel of two hundred biomarkers is worthless without a physician who will act on it. The critical question is not how many things they measure but who reads it, what their specialty is, and whether they are a licensed physician at all in the jurisdiction you are standing in.

If the answer involves an algorithm, a health coach, or a doctor who reviews reports remotely and is never in the building, you are buying data, not medicine.

Two: what happens if they find something?

This is the question that exposes most of the field. A screening operation with no clinical pathway behind it will find an abnormality, because screening at this intensity always does, and hand you a referral list.

A serious practice has established relationships with named specialists and hospitals and will tell you exactly who you would be sent to and how quickly. Ask for the names before you pay, not after.

Three: what is their false-positive rate, and do they discuss it?

Whole-body imaging and broad biomarker panels on asymptomatic people generate incidental findings at a high rate. Most are nothing. Chasing them costs money, time and a considerable amount of anxiety, and occasionally leads to invasive follow-up that carries its own risk.

A clinician who raises this unprompted is being straight with you. One who treats every finding as a vindication of the screening is selling the next tier.

A clinic that has never talked a patient out of a test is not a clinic. It is a shop.

Four: where does the data go?

You are handing over genomic data, imaging and a complete metabolic picture. Ask where it is stored, under whose control, whether it is shared with any commercial partner, and what happens to it if the business is sold. Under GDPR you are entitled to clear answers, and the quality of the answer tells you how the business thinks about you.

Five: what does the second year look like?

The first-year package is the marketed product. The question is what ongoing care actually consists of, what it costs, and whether the value is in the annual repeat or in the relationship with a physician who knows your history. If nobody can describe year two concretely, there is no year two.

Six: does your insurance settle directly?

This applies well beyond longevity clinics and is the administrative failure that catches most new arrivals. International policies vary enormously in whether they pay Greek private providers directly or reimburse you months later. Confirm direct settlement with the specific institutions you would actually use, by name, before you need them.

The unglamorous thing that matters more

Athens has private hospitals operating to Western European standards, with consultants who trained and often practised in the UK, Germany or the United States. The gap between the Greek public system's reputation abroad and the private sector's actual capability is the most persistent misconception among people who move here.

The first medical relationship worth establishing is not a longevity clinic. It is one good internist or concierge physician who holds the whole picture and routes you when something happens. Assembling specialists yourself, in a language you may not read, is how people end up with three opinions and no decision.

Do that first. Then, if you want the panel, get the panel.
