Where to get measured

You can’t manage what you don’t measure. These are the longevity clinics we visited on the quest — where we were screened, scanned and measured. Click a point on the map to step inside — and read what to ask for, below.

This is only the beginning.

Four clinics, because these are the four we actually walked into — measured, scanned, and able to tell you what it was like. Not a ranking, and not the only good ones.

Much more is coming: more clinics in more countries, what each one really tests for, what it costs, and how we experienced it ourselves. This is here to start the conversation, not to end it.

Founding Circle members hear first when it grows.

What a longevity clinic should actually do

This is the question I am asked more than any other: where should I go, and why that one? Here is what to look for. If a clinic does not do these four things, it is a spa with a blood test.

One

It measures deeply, not broadly

A full blood panel — lipids including ApoB and Lp(a), fasting insulin and HbA1c, hs-CRP, homocysteine, full thyroid, vitamin D, ferritin, liver and kidney.
Body composition: lean mass, and visceral fat specifically.
Fitness that is measured, not guessed — VO₂ max and grip strength.
Imaging that finds things early: whole-body MRI, coronary calcium or CT angiography.
Genomics once, and a biological-age clock if they will explain what it means.

Two

It looks for what kills people

Cardiovascular disease, cancer, neurodegeneration and metabolic disease account for almost every year lost. A clinic that screens hard for those four and can say what it found — and what it did not look for — is doing the job. One that leads with an intravenous drip is selling something else.

Three

A doctor reads it with you

A portal full of numbers is not a result. You want a named physician who sits with you, says what matters, what is noise, and what happens next — and who will tell you when the answer is that nothing needs doing.

Four

Somebody is there afterwards

The visit is the easy part. Ask what happens in month three: who follows the plan up, when you re-test, who you call when something changes, and whether they will talk to your own doctor. Care after the test is the difference between a diagnosis and a change.

“the first, the easy, the low hanging fruit of longevity is just don’t die of age-related chronic diseases.” Wei Wu He · CEO, Human Longevity · San Diego · 16 May 2024

“all of those tests are age neutral, and can be started as soon as possible. Not to overdo it, right?” Evelyne Bischof · Longevity physician · Shanghai · 11 December 2023

Before you book anything

What to actually ask for

A longevity clinic will sell you whatever you point at. Knowing what to ask for is most of the value — and it is the same short list whether you go to one of the four above or to a good doctor near you.

Don’t die from something stupid — something preventable, or your own unhealthy choices. Do regular check-ups, use an experienced team at a longevity clinic, and act on what they tell you.

The Longevity Map · level 04, the bridge of prevention

Bloods

About a hundred markers — in panels, not the short list a routine check-up runs
ApoB and Lp(a) — the two most people are never offered
HbA1c and hs‑CRP — sugar over months, and quiet inflammation
Hormones, thyroid, liver, kidney
Iron studies and heavy metals

Your genome, once

Full sequencing — it never changes, so you pay for it once
How you respond to medicines
Risk scores — read with a doctor, because no gene is destiny

Imaging

Full-body MRI — with diffusion imaging — that is what catches the early changes
Coronary calcium CT — and the lungs
DEXA — bone and body composition
Heart, organs, retina, skin

Function and brain

VO₂ max — the single best predictor there is
Strength and balance
A sleep test — for apnoea, which is missed constantly
Hearing and sight
Memory, processing speed, reaction time

Clocks, immune, microbiome

An ageing clock or two — a dashboard, not a verdict
Microbiome
Immune profile

You, not a panel

The tests that are yours — different for women and for men, and different by age
Family history
Sleep, stress, environment, mindset — none of it shows up in a scan

This is the short version — the questions worth asking at the desk, in our own words. The whole 360° health map, every category and what each one is actually for, is a chapter of the book. It is not medical advice, and no number here means anything until a doctor who knows you reads it: the point of a good clinic is the team who interprets the results and then tells you what to change.

Why any of this matters

The shift from sick care to health care

Almost everything we call medicine today is built to rescue you once something has already gone wrong. It is extraordinary at that. But it waits. And most of what shortens a life starts years before there is anything to rescue.

This is the whole reason the clinics on this page exist, and the reason we went to them ourselves. Not because measurement is interesting, but because the fastest way to lose this game is to miss something that was findable.

A heart attack that never happens beats one that is treated. A cancer found at stage one is a different disease from the same cancer found at stage four. And "normal" is not the same as optimal — a result inside the reference range for a population is not the same as a result that is right for you.

Prevention is the lowest-hanging fruit in longevity.
