A single blood draw measuring ~3,000 proteins reveals how your organs are aging biologically — flagging early signals of long-term disease risk years before symptoms appear. Every report is reviewed by a licensed clinician.
Thousands of proteins circulate in your plasma right now — secreted by your organs, each carrying a molecular signal about the biological state of the organ it came from. For most of human history, we had no way to read those signals at scale. Kale was founded to bring this technology to people.
No special equipment, no clinic visit. Standard lab infrastructure, extraordinary resolution.
A single test tells you where you are. Repeated tests over time tell you where you're going. Organ aging is a slow process — trajectories emerge across months and years, not weeks. Each retest adds a data point that makes the picture sharper.
Most health tests give you a snapshot with no way to track change over time. Kale is designed to be longitudinal — the value compounds with each retest. Your organ aging scores, your protein signals, and your wearable data together build a biological record that gets more meaningful the longer you use it.
Organ-level proteomic aging is one of the most replicated findings in recent biology. Protein signatures in your blood reflect the biological age of individual organs — and these signals predict major disease outcomes years before symptoms appear.
Your organ aging report covers the systems that matter most for long-term health. Each score shows how your organ's biological age compares to your chronological age.
Beyond the organ aging score, Kale reports population-normalized protein signals — composites of proteins with established biological roles, showing where your levels sit relative to people your age and sex. These are research-grade signals, not clinical diagnostics.
Each signal tells you where a group of biologically relevant proteins sits relative to people your age and sex in our reference population of 54,000+ individuals.
The signal names reflect established biological processes — the proteins in each composite have published associations with those processes in peer-reviewed literature.
These are research-grade population signals. They are not clinical diagnostic tests and should not be interpreted as diagnoses.
The organ aging scores and protein signals are the foundation. What's being built on top of them goes deeper still.
Most clinics are organized around disease. Kale is organized around you — your specific organ profile, your trajectory over time, and the interventions that actually move your numbers.
We're building toward a 2026 launch. Join the waitlist and we'll be in touch when early access is available.
