The longevity score.

Give every longevity patient a risk score they can track over time.

LifeIndex synthesizes bloodwork and wearable data into a single validated score white-labeled for your practice, delivered alongside your existing panel results.

Book a Partnership Call

Your patients leave with results. They do not leave with clarity.

Concierge and longevity medicine practices run the panels. Function Health, InsideTracker, and LabCorp deliver the data. But when a patient asks "am I actually improving?" there is no standardized answer. LifeIndex is the synthesis layer that answers that question: one score, longitudinal, benchmarked against age-matched peers.

What practices get

White-labeled reports

LifeIndex reports are embedded in your patient portal under your brand.

Score plus domain view

Each panel patient gets an overall score plus domain-level breakdown.

Trajectory tracking

Scores update as patients retest so progress is clinically visible over time.

No workflow disruption

We ingest your current panel outputs, so clinical operations stay unchanged.

Founding clinic program - 5 practices, free through 2026

We are working with five concierge and performance medicine practices to validate the scoring model against real patient populations. Founding clinics receive full access through end of 2026, direct input into model development, and named recognition when we publish the methodology whitepaper.

Built on a standardized framework

The current model is organized into cardiovascular, metabolic, recovery, and activity domains, each weighted for longitudinal signal quality.

The system is designed for comparing patient trajectory over time, not replacing clinical judgment with a point-in-time label.

Clinical FAQ

What does integration look like for the practice?

We work from your existing panel outputs and wearable summaries. Setup is scoped during onboarding and does not require replacing your current lab workflow.

What data formats do you accept from panel providers?

We support structured lab exports and normalized panel summaries. For sources with less structure, we provide a standardized intake mapping template.

Is LifeIndex a medical device or diagnostic tool?

No. LifeIndex is an informational scoring and longitudinal tracking layer. It does not diagnose, treat, or replace clinician judgment.

How is patient data handled and stored?

Data is handled in a least-necessary model with access controls and auditability. We retain structured biomarker values needed for trajectory comparisons.

What does white-labeling look like?

Reports, score summaries, and patient-facing language can be presented with your clinic identity while preserving transparent methodology framing.
