Breadth before suspicion
We do not wait for a symptom to point us somewhere. Every system is measured every time — so the quiet, early signal is never missed because no one thought to look.
Most medicine waits for symptoms. We measure the body decades earlier — over 1,284 biomarkers across every major system, read against the research and modelled into a single, honest picture of how you are aging.

Precision health is not more tests for their own sake. It is the discipline of measuring the right things, deeply, again and again — and reading them honestly against the science.
We do not wait for a symptom to point us somewhere. Every system is measured every time — so the quiet, early signal is never missed because no one thought to look.
Whole-body MRI, cardiac imaging, and advanced blood and genomic panels see structure and function the standard annual physical cannot — at the resolution research now demands.
A single reading is a dot. We re-test on schedule and model the trajectory, so the plan answers to your body — not to the population average it was first compared against.

Composite health score
Every marker is mapped to one of three zones. The chart is the story those zones tell as your plan takes effect — and where we focus next.
Markers sit in the range associated with the longest healthspan. We protect and maintain.
Trending, but not yet clinical. Caught here, most of it is reversible with the right plan.
A clear signal that deserves attention now — long before it would surface as a diagnosis.
Six systems, measured in depth. Below is a sample of the live readouts a member sees — each value placed on its zone, read against the reference range, never left as raw lab jargon.
Sample readouts
ApoB
Optimal < 80 · borderline 80–100
Lp(a)
Optimal < 75 nmol/L
Coronary artery calcium
Zero score · no detectable plaque
VO₂max
Top decile for age
Markers measured in this system
The leading cause of preventable death — caught decades early.
Sample readouts
HbA1c
Optimal < 5.4% · pre-diabetic 5.7%+
Fasting insulin
Optimal 2–8 µIU/mL
Visceral fat (MRI)
Watch 1.0–2.0 L · trending down
Liver fat fraction
Watch 5–10% · target < 5%
Markers measured in this system
How your body handles fuel — the engine of aging.
Sample readouts
hs-CRP
Optimal < 1.0 mg/L
IL-6
Watch 1.5–3.0 pg/mL
Homocysteine
Optimal < 9 µmol/L
Gut microbiome diversity
92nd percentile · high diversity
Markers measured in this system
The quiet driver behind most chronic disease.
Sample readouts
Vitamin D (25-OH)
Optimal 40–60 ng/mL
Omega-3 index
Optimal > 8% · cardioprotective
Thyroid (TSH)
Optimal 0.5–2.5 mIU/L
Ferritin
Watch 30–50 · target 50–150
Markers measured in this system
The signals that govern energy, mood, and recovery.
Sample readouts
DEXA bone density (T-score)
Normal · above −1.0 SD
Lean mass index
Above age-matched median
Grip strength
Strong predictor of longevity
Brain volume (vs age)
Above expected for age
Markers measured in this system
Bones, muscle, brain, and the body that carries you.
Sample readouts
Epigenetic age (DNAm)
Biological age below chronological
Telomere length
74th percentile for age
Glycan age
Inflammatory-aging marker
Polygenic risk (composite)
Below-average inherited risk
Markers measured in this system
Your true age — and where to spend your effort.
A single, calm, non-invasive visit captures over twelve hundred data points. Hover a site to see what we measure there.
MRI volumetrics, reaction time, processing speed
How it is captured
No radiation, no contrast. Brain, organs, spine, and soft tissue at research resolution.
Coronary calcium and structure — the earliest view of the leading preventable risk.
Over ninety markers in one sitting: lipids, metabolic, hormonal, inflammatory, nutrient.
VO₂max, grip, gait, balance, retinal and skin analysis — the body in motion, not just at rest.

Our zones are not the lab default. They are tuned to the ranges the longevity literature associates with the longest healthspan — and reviewed as the evidence moves.
Every assay, image protocol, and aging model we use is published and reproducible. If a marker is not backed by the science, it does not earn a place in your report.
Members who consent contribute, de-identified, to one of the largest prospective preventive-health datasets — which in turn sharpens every future reading.
