For decades, preventive health in the United States has been something most Americans could only dream about. Comprehensive lab testing, advanced imaging, and personalized health plans were the privileges of the wealthy — or those lucky enough to have premium insurance coverage. That is changing fast. A bold new approach to wellness is putting hospital-grade diagnostics into the hands of everyday people for just a dollar a day, and the function health membership model driving that shift is gaining serious momentum across the country.
Take control of your health starting today — a full year of 160+ lab tests, AI-powered insights, and a personalized health plan is now available for just $365. There has never been a better time to know what is actually happening inside your body.
The Problem With American Preventive Care
Most Americans walk away from their annual physical feeling like they got the bare minimum. A standard check-up typically covers around two dozen biomarkers — enough to flag an obvious crisis, but not nearly enough to catch the slow, silent conditions that build for years before symptoms ever appear. Heart disease develops over decades. Certain cancers grow quietly through early stages when treatment is most effective. By the time most people find out something is wrong, the window for easy intervention has already closed.
The traditional healthcare system was never designed for prevention. It was built around treatment — and insurance companies have reinforced that model by only covering tests once a doctor suspects a specific problem. The result is a population that is largely flying blind when it comes to its own biology.
What Function Health Actually Offers
Function Health operates on a straightforward annual membership model that flips the traditional approach on its head. Instead of waiting for symptoms, members get access to over 160 lab tests each year — more than five times what a standard physical provides. These tests cover the heart, hormones, thyroid, liver, kidneys, pancreas, metabolic health, nutrient levels, heavy metals, inflammation markers, and even early cancer signals.
The membership is now priced at $365 per year, down from its original $499 price point. That works out to exactly one dollar a day — and it includes everything: the lab testing, clinician review of results, a personalized action plan, a food guide, and a supplement list tailored to what the data actually reveals about each individual member.
All blood samples are processed at Quest Diagnostics labs by licensed technicians, using the same medical-grade standards trusted by hospitals and physicians nationwide. There are no at-home test kits, no compromised sample integrity, and no guesswork.
More Tests, More Answers — Earlier
The real power of this platform lies in what those 160-plus tests actually catch. When a large portion of members show suboptimal fasting insulin levels, or elevated cardiovascular risk markers, and most of them had no idea — that is not a coincidence. That is a system failing people who had no way to know what they did not know.
Each membership year is structured with two rounds of testing. The first round — the annual set — covers more than 100 of the most comprehensive markers available. Three to six months later, members complete a follow-up set of 60-plus tests to measure how their body has changed over time. This longitudinal view is what makes the data so valuable. A single snapshot tells you where you stand today. Repeated testing over time reveals the trajectory — and trajectory is everything in preventive medicine.
For members who want to go even deeper, add-on tests are available. These include multi-cancer early detection testing capable of identifying signals for more than 50 types of cancer — including ovarian, pancreatic, breast, colon, testicular, cervical, and melanoma — from just two vials of blood.
AI That Actually Knows Your Body
Function Health has moved well beyond a testing service. The platform now integrates artificial intelligence directly into the member experience in a way that feels genuinely personal rather than generic.
Private AI Chat allows members to ask health questions and receive answers that are informed by their own lab results, health history, and data from any connected health devices. This is not a chatbot pulling from a generic database — it is a system that understands your specific biomarkers and responds with context-aware explanations.
Protocols take that intelligence one step further by translating lab data into actionable, personalized plans covering nutrition, fitness, supplements, sleep, and stress management. These plans are not static. They adapt as new data comes in, becoming more precise with every test cycle and every piece of information a member shares.
Members can also upload past lab results, physician visit notes, and scan records into a secure health vault. That historical data feeds into both the AI Chat and the Protocols, giving the system a richer picture of each member’s health over time. In early 2026, the platform expanded its AI integration further by launching a tool that allows members to connect their health data securely with ChatGPT — giving them an even more personalized experience when using everyday AI tools for health-related questions.
Imaging That Was Once Reserved for the Wealthy
Lab testing is only part of the picture. Function Health expanded significantly into advanced imaging after acquiring a full-body MRI company in May 2025. Full-body MRI scans — which were previously priced well above $1,000 at most facilities — are now available to members at $499, using FDA-cleared AI technology that cuts scan time from roughly an hour down to just 22 minutes.
These scans are designed to detect early signs of cancer, unruptured brain aneurysms, endometriosis, stroke risk, and a range of other serious conditions that standard physicals would never catch.
For members focused specifically on cardiovascular health, a Heart and Lungs CT add-on is available at $349. This single low-dose, three-minute scan screens for lung cancer signals and produces a coronary artery calcium score — a key indicator of heart disease risk — all reviewed remotely by a medical professional.
No Insurance Required — No Surprise Bills
One of the most refreshing aspects of this membership model is its total transparency. There are no deductibles. There are no co-pays. There are no surprise bills arriving weeks after a test. The annual membership fee covers what it covers, and every add-on is priced clearly and upfront before a member commits to anything.
The membership is also FSA and HSA eligible, which means members paying through a pre-tax health account can reduce the effective cost by 20 to 30 percent depending on their tax bracket. Employers can also fully or partially fund memberships as part of a corporate wellness benefit — a feature that is gaining traction as companies look for meaningful ways to invest in employee health without navigating insurance complexity.
A Growing Platform Built for the Long Haul
Function Health is not a startup experiment anymore. The company has raised significant institutional backing at a multi-billion-dollar valuation, has crossed hundreds of thousands of members, and has processed tens of millions of lab tests since launching in 2023. Its leadership team includes some of the most respected names in medicine — including a former Cleveland Clinic physician serving as Chief Medical Officer and the inventor of parallel MRI technology serving as Chief Medical Scientist.
The platform has also forged partnerships with professional sports organizations and major wellness brands, bringing its testing capabilities to elite athletes and workplace wellness programs alike. These partnerships are not just marketing moves — they generate real-world data at scale that continues to improve the platform’s ability to spot health trends and refine its recommendations.
Why This Moment Matters
Healthcare in the United States is expensive, complicated, and often reactive. Most people do not engage with the system until something goes wrong — and by then, the cost of treatment is exponentially higher than what preventive intervention would have been. A function health membership does not replace a primary care doctor. What it does is make members dramatically better patients. They walk into appointments knowing their numbers, understanding their trends, and asking informed questions instead of nodding along to a rushed 15-minute visit.
At $365 a year, this level of insight is no longer out of reach for the average American. The tests included in a single membership would cost over $15,000 if ordered individually at standard market rates. That math alone tells a story about how broken the current system is — and how powerful it can be when someone builds a smarter alternative.
