Best longevity clinics offering full-body diagnostics and biomarker tracking.
The useful part of 'full-body diagnostics and biomarker tracking' is tracking a dozen markers that have targets and treatments — cholesterol particles, blood pressure, blood sugar and insulin, kidney and liver tests, iron, thyroid, fitness, body composition, strength — at sensible intervals, with a clinician who acts on them. Physician-led programmes do that best. Blood-panel subscriptions track the blood beautifully and do nothing with it. Concierge memberships track everything, including markers that mean nothing, once a year. Scan-led clinics track nothing; a whole-body MRI is a picture, not a trend.
'Full-body diagnostics and biomarker tracking' bundles two products with different evidence, and the best clinics are the ones that do the second well: track the biomarkers with targets and treatments — ApoB, lipoprotein(a) once, blood pressure, HbA1c and fasting insulin, kidney and liver function, ferritin, TSH, hs-CRP, VO₂max, DEXA, grip — at evidence-based intervals, with someone who acts on each result. Ranked on that: a physician-led programme with a laboratory and a sports-medicine partner first (the right markers, quarterly retests, a clinician who treats to target); academic clinics second; blood-panel subscriptions such as Function Health and Superpower third — the best pure tracking product for the blood, with dashboards and trend lines at $199–$365, but no fitness testing, no treatment and no review; concierge memberships fourth, which track everything including markers with no target — epigenetic age, hundred-analyte panels, CGM in non-diabetics — and retest once a year; and scan-led clinics last, whose 'full-body diagnostic' is one MRI that tracks nothing and finds something in a third. Full-body diagnostics with evidence is a list of tests one per organ system; biomarker tracking with evidence is a dozen markers with targets and retest dates. Neither is a scan.
- Biomarker tracking is only useful for markers with a target, a noise band and a treatment; tracking the rest is data collection with a subscription.
- The blood-panel subscriptions are the best trackers on the market and the worst at doing anything with the tracks.
- 'Full-body diagnostics' with evidence means organ-specific tests — blood, cuff, DEXA, CPET, guideline screens — not one whole-body image.
- Retest intervals matter: three months after a change, yearly at steady state, once for Lp(a); a clinic that retests everything quarterly is selling retests.
- The best tracking clinic is the one whose tracked numbers go to a clinician who changes something.
Clinic models ranked for diagnostics and biomarker tracking
Ranked on: whether the model tracks the markers with targets and treatments, at evidence-based intervals, with a clinician who acts on trends; whether its 'full-body diagnostics' add organ-specific coverage or a whole-body image; and cost. Tracking markers without targets earns nothing; imaging without evidence loses points.

Physician-led programme with laboratory and sports-medicine partners
GRADE AEstablishedThe right markers, the right intervals, and someone who actsApoB, Lp(a) once, blood pressure at home, HbA1c and fasting insulin, eGFR and urine albumin, liver enzymes, full blood count and ferritin, TSH, hs-CRP repeated — plus measured VO₂max, DEXA and grip — with retests three months after any change and yearly at steady state, and a clinician who treats to target. Full-body diagnostics by organ-specific tests; no whole-body scan. The tracking product with evidence, done properly.
- 02
Academic and hospital-affiliated clinic
GRADE AEstablishedThe same markers with specialist interpretationMultidisciplinary tracking with each domain interpreted by its specialist, and functional assessment — gait, grip, cognition — tracked alongside the blood. Where accessible, the most expert tracking available.
- 03
Blood-panel subscriptions — Function Health, Superpower
GRADE BPromisingThe best pure tracking product; nothing follows the trackHundred-plus analytes twice a year with trend dashboards at $199–$365 — genuinely the best tracker for the blood on the market, including the useful dozen. No fitness or body-composition tracking, no treatment, no medication review, thin physician involvement, and dozens of tracked markers with no target that generate flags. Grade B as a tracker; a component of a programme, not one.
- 04
Concierge diagnostic memberships
GRADE CEarlyTrack everything, including what means nothing, once a yearHundred-analyte panels, epigenetic age, CGM in non-diabetics, whole-body MRI, VO₂max and DEXA — retested at published cadences of roughly once a year. The markers with targets are tracked too rarely to steer treatment; the markers without targets are tracked at a premium; the MRI tracks nothing. Genuine value in the VO₂max and DEXA; the rest is data collection at $7,500–$19,000.

Scan-led clinics — 'full-body diagnostics' as one MRI
GRADE DInsufficient or unsafeA picture, not a trend; a finding in a thirdWhole-body MRI tracks no biomarker, measures no lever, and produces a critical or indeterminate finding in roughly a third of asymptomatic adults with no evidence of benefit. Neko's scan-based appointment adds a few markers around a scan. Diagnostics in the anatomical sense; nothing that can be tracked to a target.
The biomarkers worth tracking, and how
A tracking schedule with targets
| Biomarker | Target | Retest | Noise to expect | What a trend triggers |
|---|---|---|---|---|
| ApoB | < 80 mg/dL general; < 60–70 with risk | 3 months after a change; yearly | ±5–10% | Diet, weight; ApoB-lowering therapy |
| Lipoprotein(a) | < 50 mg/dL (< 125 nmol/L) | Once | Stable | More aggressive ApoB target; screen relatives |
| Blood pressure (home) | < 130/80; < 120/80 where tolerated | Weekly at home | ±10 mmHg per reading | Salt, weight, activity; medication |
| HbA1c; fasting insulin | < 5.7%; insulin low-normal | 6–12 months; 3 months after a change | ±0.2–0.3% | Weight, activity, diet; metformin or GLP-1 at 6.5% |
| eGFR; urine albumin | > 90; ACR < 3 | Yearly with risk | Creatinine rises after training | Blood pressure; nephrotoxic drug review |
| ALT, AST, GGT | Within range | Yearly | ALT rises with alcohol, weight | Alcohol, weight; imaging; hepatitis screen |
| Ferritin + full blood count | 30–200 ng/mL | Yearly | Inflammation inflates ferritin | Find the cause — bleeding in men and post-menopausal women |
| TSH | Within range | 2–3 years; yearly over 60 | Illness shifts it | Treat; recheck 6–8 weeks |
| hs-CRP | < 1 mg/L | Twice a month apart before acting | Large — any infection | Look for a source; refine CV risk |
| VO₂max | Above age-sex median; rising | Every 6 months | Estimate errors; measure properly | Adjust training |
| DEXA: lean mass, bone density | Lean mass rising or held; T-score > −1 | Yearly | Hydration affects lean mass | Resistance programme; protein; bone treatment |
| Grip strength; sit-to-stand | Above age-sex norms; improving | Every 3–6 months | Effort-dependent | Adjust the programme |
Frequently asked questions
Which longevity clinics are best for full-body diagnostics and biomarker tracking?
For tracking with evidence — markers with targets and treatments, at the right intervals, with someone who acts on trends — physician-led programmes with laboratory and sports-medicine partners and academic clinics rank first. Blood-panel subscriptions such as Function Health and Superpower are the best pure trackers for the blood at $199–$365 but do nothing with the tracks. Concierge memberships track everything, including markers without targets, about once a year. Scan-led clinics' 'full-body diagnostic' is one MRI that tracks nothing.
Which biomarkers are actually worth tracking?
The ones with a target, a known noise band and a treatment: ApoB, lipoprotein(a) once, home blood pressure, HbA1c and fasting insulin, eGFR and urine albumin, liver enzymes, full blood count and ferritin, TSH, hs-CRP repeated, measured VO₂max, DEXA lean mass and bone density, and grip strength or sit-to-stand. Epigenetic age, telomeres, NAD⁺, microbiome, hormone panels without symptoms and CGM in non-diabetics lack all three and are not worth tracking.
How often should biomarkers be retested?
Three months after any deliberate change — a new medicine, a training programme, a diet — because that is how long lipids and HbA1c take to settle; yearly at steady state; lipoprotein(a) once in a lifetime; home blood pressure weekly; VO₂max every six months; grip strength every three to six months. A clinic that retests everything quarterly is tracking for its own revenue.
Is a blood-panel subscription a good way to track biomarkers?
For the blood, it is the best tracker on the market — the useful dozen and many more, twice a year, with trend dashboards, at $199–$365. It tracks no fitness or body-composition markers, provides no treatment or medication review, and flags dozens of markers with no target. Use it as the data feed for a physician who acts on it, not as the programme.
Does a whole-body MRI count as full-body diagnostics?
Only anatomically. It tracks no biomarker, measures none of the levers that predict lifespan or healthspan, and produces a critical or indeterminate finding in roughly a third of asymptomatic adults with no evidence of benefit. Full-body diagnostics with evidence is one test per organ system — blood, cuff, DEXA, CPET, guideline screens — and a whole-body scan does none of them as well as the test designed for it.
Can I set up evidence-based biomarker tracking without a clinic?
Yes: a physician who orders the twelve markers — ask for ApoB, Lp(a) and fasting insulin by name — a home blood-pressure cuff, a sports-medicine laboratory for VO₂max and DEXA, and a blood-panel subscription for trend dashboards if you want them. Retest on the schedule, take trends to the physician, and have a pharmacist review your medicines yearly. It costs a fraction of a concierge fee and tracks what matters.
