How to choose the best longevity center for testing?
Pick a longevity testing centre by asking, in order: does it run the tests I actually need (cholesterol particles, blood pressure, fitness and body-composition testing, heart calcium scoring, cancer screening) rather than the ones it has machines for; who interprets the results; who follows up abnormal ones with a plan and a retest; who manages and pays for what a scan finds by accident; is the lab and imaging accredited; and what does each test cost. Hospital-linked and physician-led centres with a real lab and sports-medicine unit usually win; centres whose front page is a scanner usually do not.
Choose a longevity centre for testing by ranking what matters about testing in order: first, whether the centre runs the tests you actually need — the evidence-based panel with ApoB and Lp(a), blood pressure, CPET VO₂max, DEXA, coronary calcium scoring at intermediate risk, guideline cancer screening — rather than the tests it owns a machine for; second, who interprets the results, because a test is worth exactly what the clinician reading it does with it; third, follow-through — a written plan and retest date for each abnormal result, with a medication review; fourth, cascade management — a written protocol and pricing for incidental findings, which decides whether imaging is safe to have there; fifth, accreditation and equipment quality — a CLIA-certified laboratory, an accredited imaging facility, a CPET performed to protocol; and sixth, price by line, so the evidence-free tests are visible. The best centre for testing is usually a hospital-affiliated or physician-led centre with a proper laboratory and a sports-medicine unit, and it is rarely the one whose front page is a scanner.
- Choose the tests first, then the centre that runs them; centres choose the tests they own equipment for.
- Interpretation is the product; the same ApoB result is worth nothing from a dashboard and everything from a physician who treats to target.
- Follow-through is what turns a test into care, and it is the criterion diagnostics-led centres fail most.
- Incidental findings are a certainty with imaging; a centre without a written cascade protocol has not thought about its product.
- Accreditation is checkable — CLIA for the lab, accreditation for imaging — and worth more than a brochure's word 'advanced'.
The criteria, ranked in the order to apply them
Ranked on: how much each criterion determines whether testing at the centre improves an outcome rather than producing a report, and how often centres fail it. The order is the order to ask.
| # | Option | Verdict | Grade |
|---|---|---|---|
| 1 | 1. Does it run the tests you need — not the tests it owns? | The evidence-based list, decided before the visit | GRADE AEstablished |
| 2 | 2. Who interprets the results? | A physician who treats to target, or a dashboard | GRADE AEstablished |
| 3 | 3. Follow-through on abnormal results | A plan and a retest date, including a medication review | GRADE AEstablished |
| 4 | 4. Cascade management for incidental findings | Decides whether imaging is safe to have there | GRADE BPromising |

1. Does it run the tests you need — not the tests it owns?
GRADE AEstablishedThe evidence-based list, decided before the visitApoB and Lp(a), blood pressure, HbA1c and fasting insulin, kidney and liver function, blood count and ferritin, TSH; CPET VO₂max and DEXA; coronary calcium score at intermediate risk; guideline cancer screening coordinated; low-dose CT for heavy smokers. Write the list first and ask the centre which it runs. A centre that redirects you to its whole-body MRI has answered.
- 02
2. Who interprets the results?
GRADE AEstablishedA physician who treats to target, or a dashboardAsk which clinician reviews your results, their specialty and board certification, and whether they will prescribe and adjust to target. Results reviewed asynchronously by an app or a generalist reading against reference ranges are data; results reviewed by a preventive cardiologist or internist treating ApoB to a risk-based target are care.
- 03
3. Follow-through on abnormal results
GRADE AEstablishedA plan and a retest date, including a medication reviewFor each abnormal result, who acts, what the plan is, when the retest is and whether it is included. A pharmacist's review of current medicines and supplements belongs here, because several move the very markers being tested. A centre that emails results and offers a retest to buy has no follow-through.
- 04
4. Cascade management for incidental findings
GRADE BPromisingDecides whether imaging is safe to have thereIf the centre images, ask for its written protocol for indeterminate findings, who manages them, and who pays for the follow-up imaging and biopsies — roughly a third of whole-body MRIs and a fair share of chest CTs produce one. No protocol, no imaging there.
- 05
5. Accreditation and equipment quality
GRADE BPromisingCheckable; more meaningful than 'advanced'A CLIA-certified (or national equivalent) laboratory; accredited imaging with radiologist reporting; CPET performed on a metabolic cart to a recognised protocol with a physician present, not a submaximal estimate; DEXA on a calibrated scanner with the same machine at follow-up. Ask; the good centres answer readily.
- 06
6. Price by line
GRADE BPromisingMakes the evidence-free tests visibleLine pricing shows that the evidence-based panel costs little and the whole-body MRI, epigenetic age and hundred-analyte add-ons cost most. Package pricing hides that. Ask for lines and decline the expensive ones without evidence.
The questions, and the answers that decide
What to ask a longevity testing centre
| Ask | A good answer | A disqualifying answer |
|---|---|---|
| Do you measure ApoB and lipoprotein(a)? | Yes, on every panel; Lp(a) once | 'We do a full lipid profile' (LDL only) |
| Is VO₂max measured by CPET with gas exchange? | Yes, metabolic cart, protocol, physician present | Estimated from a wearable or a submaximal test |
| Who reviews my results and what do they treat to? | A named internist or cardiologist; risk-based targets | An app; reference ranges; 'optimal' ranges the centre defines |
| What happens after an abnormal result? | A written plan, prescription if needed, retest at three months, included | A retest to purchase; a supplement recommendation |
| Does a pharmacist review my medicines? | Yes, at baseline | No |
| What is your protocol for an incidental finding on imaging? | Written; managed in-house or by named referral; follow-up priced | 'We'll refer you' |
| Is the lab CLIA-certified and the imaging accredited? | Yes, with names | 'Medical-grade' |
| Can I have line pricing and decline the MRI? | Yes | Package only |
Frequently asked questions
How do I choose the best longevity centre for testing?
Apply six criteria in order: does it run the tests you actually need (ApoB and Lp(a), blood pressure, CPET VO₂max, DEXA, calcium scoring at intermediate risk, guideline screening) rather than the ones it owns machines for; who interprets the results and to what target; whether each abnormal result gets a plan, a retest and a medication review; whether it has a written protocol and pricing for incidental findings; whether the lab and imaging are accredited; and whether it prices by line. Hospital-affiliated and physician-led centres usually pass; scanner-led centres usually do not.
Which tests should a longevity centre be able to run?
The evidence-based panel — ApoB, lipoprotein(a), HbA1c and fasting insulin, kidney and liver function, full blood count and ferritin, TSH, hs-CRP — plus blood pressure, a cardiopulmonary exercise test for VO₂max, DEXA, coronary calcium scoring at intermediate risk, coordinated guideline cancer screening and low-dose CT for heavy smokers. If the centre cannot measure ApoB or CPET VO₂max but can do a whole-body MRI, it has the wrong equipment.
How do I know if a centre's VO₂max test is a proper one?
Ask whether it is measured by cardiopulmonary exercise testing with gas exchange on a metabolic cart to a recognised protocol, with a physician present, rather than estimated from a wearable, a heart-rate formula or a submaximal test. A measured VO₂max is one of the strongest predictors of mortality and the best reason to use a centre; an estimate is not worth the trip.
What should happen after an abnormal test result at a longevity centre?
A named clinician should give you a written plan — prescription or lifestyle change — a retest date three months out included in the fee, and a pharmacist's review of the medicines and supplements that may be moving the marker. A centre that emails the result and offers a retest to buy, or recommends a supplement it sells, has no follow-through.
Should I have imaging at a longevity centre?
Only imaging with an indication — a calcium score at intermediate cardiovascular risk, low-dose chest CT with a heavy smoking history — and only at a centre with a written protocol and pricing for incidental findings. Whole-body MRI produces a critical or indeterminate finding in about a third of asymptomatic adults with no evidence of benefit; a centre without a cascade protocol has not thought about what it sells.
Can I get better testing without a longevity centre?
Often, yes: a physician who orders the evidence-based panel from an accredited laboratory, a sports-medicine unit for CPET and DEXA, the screening programme for cancer tests, and a pharmacist for the medication review. It passes the six criteria by construction and usually costs less. A centre is worth choosing when it coordinates all of that and interprets it well; otherwise you have built the better centre yourself.
