Longevity Labs
Comprehensive, clinician-guided lab testing built to find the patterns standard panels miss. Over 80 biomarkers across 13 body systems — so you stop guessing and start knowing.
If you're not testing, you're not learning.

The Full Picture
Built on a decade of clinical work with 50,000 patients. Each panel captures what matters and skips what doesn't, connecting the dots across every major system in your body.
Why It's Smarter
Every biomarker was hand-picked by functional medicine physicians with one filter: does this actually change what we do for the patient?
Captures how you feel today and where your body is headed if nothing changes. Both windows matter for real treatment decisions.
Flags the early signals that most standard labs won't catch until they're harder to fix. Prevention over reaction, every time.
Focuses on the biomarkers most tied to energy, performance, and how long your body stays functional at a high level.
Your results get compared against real-world clinical data, so the context behind each number actually means something.
Your Personal Readout
We take 80+ data points and turn them into three clear numbers. No binder of lab results you'll never finish reading.
One clinician-informed number showing how well your body systems are working together right now.
Why it matters: An at-a-glance view makes it easier to track your overall health trend over time without drowning in data.
A measure of how your body is actually functioning today compared to what's typical across different life stages.
Why it matters: Puts your results in context and shows where focused attention would make the biggest difference.
An indicator of how quickly your body is changing over time, independent of your calendar age.
Why it matters: Helps you understand your trajectory and spot trends before they escalate into something harder to reverse.
Deep Dive
Every number in your results is a chapter. Here is what each panel is actually looking for — and why it matters for how you feel, perform, and age.
Your immune system is designed to protect you. But sometimes it misfires and starts attacking your own tissue — often silently, for years, before symptoms show up. This panel catches the earliest signals of autoimmune activity so your care team can act before damage accumulates.
Electrolytes carry electrical charges through your blood and cells. They control how your nerves fire, how your muscles contract, how your heart beats, and how your kidneys manage fluid. An imbalance here touches everything — energy, cognition, and cardiovascular rhythm.
Your blood is a constantly moving ecosystem of red cells, white cells, and platelets. The CBC is the most information-dense single test in medicine — it reveals how well you're carrying oxygen, how ready your immune system is, whether you're anemic, and whether your bone marrow is working as it should.
Hormones regulate energy, mood, sex drive, muscle mass, fat distribution, sleep, and cognitive clarity. A single imbalance ripples through multiple systems — which is why treating symptoms without testing hormones is like guessing in the dark.
Metabolic dysfunction is behind the majority of chronic disease — diabetes, cardiovascular disease, fatty liver, hormonal imbalances, and cognitive decline all have metabolic roots. Most of it develops silently over years. This panel catches the drift early, when it's still completely reversible.
Acute inflammation is how your body heals. Chronic low-grade inflammation is how your body breaks down — quietly accelerating heart disease, cancer, neurodegeneration, and hormonal decline. These markers detect that background fire before it does lasting damage.
Your kidneys filter about 200 liters of blood every day, removing waste, regulating electrolytes, controlling blood pressure, and activating vitamin D. Kidney decline is usually silent until significant function is already lost — this panel catches the early signs when intervention still makes a major difference.
Heavy metals and environmental toxins accumulate in the body over time from food, water, air, and occupational exposure. They disrupt hormones, impair cognition, damage the kidneys, and accelerate inflammation — often without obvious symptoms for years.
Your thyroid sets the speed of almost every metabolic process — energy production, temperature regulation, heart rate, gut motility, cognitive speed, and weight management. Standard care often only tests TSH, which misses the full picture. This panel gives you the complete view.
Half of all heart attacks happen in people with "normal" cholesterol. The standard lipid panel misses the most important risk factors. This panel goes deeper — looking at particle quality, inflammatory burden, and vascular health markers that actually predict events decades in advance.
Your adrenal glands produce the hormones that manage your stress response, blood pressure, energy, and inflammation. Chronic stress burns through adrenal reserves, disrupts the cortisol rhythm, and shifts the body into a catabolic state — breaking down muscle, storing fat, suppressing immunity, and impairing sleep.
Micronutrient deficiencies are more common than most people realize — and they don't always show up as obvious symptoms. Instead they show up as persistent fatigue, low mood, poor recovery, brain fog, and hormonal imbalances that supplements never seem to fix because the wrong ones are being taken.
The liver performs over 500 functions — metabolizing hormones, producing proteins, filtering toxins, regulating cholesterol, managing blood sugar between meals, and activating vitamins. Liver stress is extraordinarily common in modern life and rarely causes symptoms until significant damage has already occurred.
