A complete picture of your biology — curated without compromise. So you can see your health clearly, understand what it means, and act on it with confidence.
Longevity medicine is not about living forever. It is about compressing the years of disease and decline into the smallest possible window — and expanding the years of health, clarity, and vitality to fill the rest. River gives you the biological intelligence to do exactly that.
Determined by your genetics, your environment, and the decisions made — or not made — decades before symptoms appear. Genomics, epigenetics, cardiometabolic markers, and cancer risk profiling read your biological future before it arrives.
Determined by the quality of your biology day to day — your metabolism, your microbiome, your hormone balance, your cognitive reserve, your sleep architecture. Data without interpretation, integration, and guidance is noise. River turns it into a protocol.
Together they form a complete molecular intelligence picture. Alone, each is partial. River curates access to all six — sourced from the world-class specialist for each domain.
The instruction manual you were born with.
A real-time snapshot of your body's chemistry.
The proteins your cells are actually producing right now.
How your life is switching your genes on and off.
The 38 trillion organisms shaping your health from within.
The deep signals that routine blood tests never reach.
The biological stack tells you what your molecules are doing. The diagnostic suite tells you what your body is doing — its structure, its capacity, its function. Together they form a complete baseline that no single test can provide.
Imaging & Structural
Body Composition
DEXA Scan
The gold standard for body composition — fat mass, lean mass, bone density, and visceral fat measured with sub-millimetre precision. The quarterly baseline every River member starts with.
Quarterly baseline
Organ Screening
Low Dose CT Scan
A full-body or targeted CT scan at a fraction of the standard radiation dose — detecting early lung, abdominal, and soft tissue changes before they become clinical problems. Screening, not diagnosis.
Early detection
Liver Health
FibroScan
A non-invasive ultrasound scan that measures liver stiffness and fat content — the earliest reliable indicator of fatty liver disease, which affects an estimated 1 in 3 urban Indians and is almost never caught early.
Non-invasiveCardiovascular
Cardiovascular Risk
CAC Scoring
Coronary Artery Calcium scoring via CT — identifies atherosclerosis and heart disease risk a decade before a cardiac event. The test cardiologists wish every patient over 40 would take.
Early cardiac detection
Cardiovascular Fitness
VO₂ Max
The single strongest predictor of longevity in all of medicine. Your maximal oxygen uptake determines how long and how well you live — more powerfully than cholesterol, blood pressure, or BMI.
Strongest longevity predictorMetabolic & Cellular
Routine Pathology
Comprehensive Blood Panel
The clinical blood tests your doctor orders — CBC, lipid panel, thyroid, liver, kidney, hormonal — done through labs we've vetted for scientific rigour, not price. 120+ markers, not the standard 12.
120+ markers
Toxin Burden
Heavy Metals & Toxin Burden
Blood and urine-based analysis for lead, mercury, arsenic, cadmium, and other toxic metals that accumulate silently over years. A significant and underdiagnosed contributor to fatigue, cognitive decline, and cardiovascular risk — especially in urban India.
Silent risk factor
Body Composition
InBody BCM Analysis
A precise, non-invasive measurement of body composition — segmental muscle mass, fat mass, visceral fat level, and cellular health markers. Goes beyond weight and BMI to show exactly what your body is made of and how it is changing over time.
Segmental analysisNeurological & Sensory
Sleep Architecture
Sleep Architecture Test
Home sleep testing — sleep stages, oxygen saturation, apnoea detection, and circadian rhythm analysis. Sleep quality is one of the most powerful longevity levers in existence, and the most consistently ignored by standard medicine.
Home collection
Hearing & Cognitive Risk
Audiometric Test
Hearing loss is one of the most underdiagnosed longevity risks — strongly linked to cognitive decline, social isolation, and accelerated brain ageing. Catching it early changes the entire trajectory.
Cognitive link
Eye & Vascular Health
Ophthalmology & Retinal Imaging
The retina is the only place in the human body where blood vessels and nerve tissue can be examined without surgery — making it a direct window to cardiovascular health, early diabetes, and neurological decline.
Window to brain healthWearables and connected devices track what your body does every hour of every day. River helps you choose, integrate, and — crucially — interpret what they're telling you in the context of your full biological picture.
Continuous Activity
Activity & Heart Monitoring
Heart rate, heart rate variability, blood oxygen, movement, and ECG — tracked continuously across every waking and sleeping hour. The longitudinal data layer that no single clinical visit can provide.
Sleep Architecture
Sleep & Recovery Tracking
Sleep stages, sleep efficiency, overnight temperature trends, and recovery readiness — measured nightly. Sleep quality is one of the most powerful longevity levers in existence, and one of the most ignored.
Metabolic Response
Continuous Glucose Monitoring
Real-time glucose response to every meal, stress event, and night of sleep — worn as a small sensor on the arm. The single most revealing window into your metabolic health, measured continuously rather than once a year.
Body Composition
Smart Body Composition Tracking
Fat mass, lean muscle mass, bone density, and hydration — tracked weekly at home. Paired with your quarterly DEXA scan baseline, this gives a continuous view of how your body composition is shifting between clinical visits.
"Like a river, your health is shaped by everything that flows into it."
Each layer alone is a partial truth. Your wearable sees behaviour. Your diagnostics see structure. Your biological stack sees the molecular why beneath both. Only when all three are interpreted together does a complete longevity picture emerge — and only then can meaningful action follow.
Layer 01
Biological Stack
The molecular why. Genomics, metabolomics, epigenetics, microbiome, proteomics, biomarkers — the intelligence beneath every symptom and every test result.
Layer 02
Diagnostic Suite
The structural what. DEXA, VO2 Max, CAC scoring, blood panels, sleep testing — what your body's structures and systems are doing right now.
Layer 03
Connected Health
The continuous how. Devices that track your body every hour of every day — giving the longitudinal data that snapshots cannot provide.
"Your wearable sees the surface.
The biological stack sees beneath it."
If your clinic already operates a DEXA scanner, an echo lab, a sleep study programme, or a comprehensive blood panel service — River's biological stack is the missing layer that makes every one of those instruments tell a more complete story.
Seven specific reasons. Not values statements. Not marketing language.
01 · Curation
River selects one partner per specialty — the one that meets our scientific standard. Not the cheapest. Not the most convenient. The best.
02 · Post-test counselling
We sit with you and explain what your report means for your life. You are never left alone with data you cannot interpret.
03 · Trend reporting
River provides trend summaries showing results across multiple tests — so you and your doctor see how your biology is changing, not just where it stands today.
04 · Partner enablement
River trains the clinics it works with — on tests, on genomics, on communicating results. We don't just supply tests. We build capability.
05 · Human touch
River believes health decisions need human guidance. Relationships, physical presence, and personal conversation are core — not optional extras.
06 · Selective partnership
The same rigour River applies to testing partners, it applies to who it works with. This is the only way to guarantee quality on both sides.
07 · AI-readiness
River is building with the understanding that AI will reshape diagnostics and longevity — and is positioning to be on the right side of that shift.
River was founded on two decades of genomics expertise and years of hands-on health coaching — combined with a deliberate scientific advisory network spanning India and the USA.
