Geviti vs Function Health: Which Platform is Right for You?

Personalized health optimization is booming, and two major players—Function Health and Geviti—offer different takes on lab testing, follow-up care, and overall longevity support. If you’ve heard about both but aren’t sure which is the better fit, this guide highlights the unique features of each program, including the biomarker breakdown, pricing, and the type of support you can expect.

Why Health Optimization Matters

Before diving into the details, let’s set the stage: health optimization is about more than just blood tests and lab results. Functional health is a key component of modern health optimization, focusing on personalized healthcare approaches, longevity strategies, and comprehensive health management.

It’s about a holistic approach to preventative healthcare, where you regularly measure biomarkers, receive personalized insights, and take immediate action to improve health outcomes. Functional medicine emphasizes prevention, early detection, and addressing root causes, offering a tailored and integrative approach that goes beyond conventional medicine.

With that in mind, understanding each platform’s strengths—and where one might outshine the other—can guide you toward the best program for your individual goals. The landscape of preventative health and longevity medicine continues to evolve rapidly, with AI and technology enabling more data-driven, personalized health insights.

Function Health: A Health Snapshot

Overview

Function Health aims to help you “live 100 healthy years” by offering once-a-year comprehensive testing for over 100 biomarkers, plus a follow-up test of about 60 biomarkers several months later. Function Health was co-founded by Mark Hyman, a leader in functional medicine.

The initial Function Health panel includes 100 biomarkers, with a follow-up panel of about 60 biomarkers 3 to 6 months later. The $365 annual membership fee covers access to over 100 lab tests each year, but the function health cost does not include the price of blood work, which varies by state and location. Function Health accepts HSA/FSA cards.

Core Benefits

1. Wide Biomarker Range
   Function Health’s first panel covers more than 100 biomarkers, providing a whole body assessment that includes kidney function, detailed LDL fractionation, thyroid hormones (T3, T4, TSH, and antibodies), and advanced urinalysis. You’ll see a broad snapshot of metabolic, cardiac, kidney, and autoimmune markers in one go.
   
2. Straightforward Data Dashboard
   Test results appear in an easy-to-read interface that helps you interpret your blood work and spot trends across multiple body systems over time.
   
3. Cost-Effective Entry Point
   An annual fee of $365 for two lab sessions (one full, one follow-up) offers a clear, upfront cost structure that’s easy to manage.

Main Limitations

1. Limited Follow-Up and Treatment
   Function Health delivers lab data and basic guidance. If you need interpretation, coaching, or treatment, you’ll have to bring your results to a separate provider.
   
2. No At-Home Testing
   You must visit a Quest Diagnostics location for each draw, which can be inconvenient if scheduling or travel is a challenge.
   
3. Only Partial Coverage of Some Markers
   You get some advanced testing, like cholesterol particle size, but miss other important biomarkers like vitamin B12 and progesterone. Additionally, many essential biomarkers only get tested once per year - notably hormones, thyroid, and nutrients.
   
4. More Comprehensive Than Annual Physicals
   Traditional annual physicals usually cover only basic health markers and focus on normal parameters. In contrast, Function Health offers more comprehensive biomarker testing, providing a broader view of your health.
   
5. Long Wait Times
   It takes about 3-4 weeks to get bloodwork results back.
   
6. Wearable Integration
   Currently, there’s no direct link with devices like Apple Health, Oura, or Whoop, so your daily metrics remain separate from your Function Health results.

Geviti: A Comprehensive Health Optimization Solution

Overview

Geviti offers a more involved approach, combining twice-yearly biomarker testing with ongoing medical support, coaching, and lifestyle guidance. Geviti provides a 'Longeviti Blueprint' for actionable insights and ongoing health coaching, helping you translate results into meaningful changes.

Rather than just handing you data, Geviti makes it easy to act on it, whether that means adjusting your diet, starting custom supplements, or exploring Rx therapies. Geviti emphasizes at-home blood draws through concierge phlebotomy, offering a convenient alternative to traditional lab visits. Their comprehensive testing covers multiple systems of the body for a holistic assessment. Geviti also offers wholesale pricing on peptides and discounts on supplements, making it more cost-effective compared to standard markups.

Core Benefits of Geviti

1. Broad Yet Targeted Biomarker Coverage
   Every six months, Geviti measures 100+ different markers, including everything from thyroid hormones (T3, T4, TSH) and metabolic markers (HbA1c, insulin) to essential vitamins (B12, Vitamin D) and advanced lipids (LDL, HDL, ApoB). With Geviti, you get the exact same test every 6 months, instead of a smaller second test. Test results are also available much sooner, typically in about 1 week.
   
2. In-House Interventions & Personalized Plans
   Unlike Function Health, Geviti offers direct medical guidance. You can meet with specialists 1-on-1 and get treatment right away. If your tests show a hormonal imbalance, Geviti can prescribe relevant therapies (such as peptides or hormone treatments) and adjust your regimen in real time.
   
3. At-Home Test Kits & Wearable Integration
   Many members choose at-home blood draws for added convenience, and Geviti’s platform can integrate data from devices like Apple Health and Oura, giving you a more continuous view of your well-being.
   
4. Coaching & Check-Ins
   With Geviti, you don’t just get numbers; you also have ongoing access to health coaches and clinicians who help you interpret, adapt, and optimize your care plan between testing rounds.

Pricing and Value

Geviti’s membership ranges from $53 to $149 per month, which includes all lab work, results consultations, and access to personalized interventions at wholesale prices. Function Health, by comparison, has a fixed annual cost of $365. Both Geviti and Function Health are HSA/FSA eligible, though coverage depends on individual plans. While you may spend more money upfront with Geviti, investing that money in comprehensive health services can provide long-term benefits and greater value through ongoing coaching, medical follow-ups, and in-house treatment options—many members find these added services worth the investment.

Biomarker Breakdown: A Closer Look

Geviti and Function Health are two companies at the forefront of advanced medical testing services, providing patients with access to comprehensive lab tests and diagnostics that go beyond traditional healthcare offerings. Both platforms offer extensive biomarker panels designed for health optimization and longevity, making it easier for individuals to gain deep health insights and personalized protocols. Biomarker testing through these services can help monitor early indicators of diseases such as diabetes, cancer, and cardiovascular issues.

Here’s a quick overview of how Function Health’s lab tests compare to Geviti’s. While both panels measure many of the same items—like cholesterol, blood sugar, and sex hormones—each service has its unique extras.

Function Health Highlights

• LDL Fractionation: Breaks down LDL into small, medium, and large sub-particles.
• Comprehensive Urinalysis: Repeated two times a year.
• Omega-3/6 Ratios: Reflects fatty acid balance.
• Smaller second test: Midyear test does not include hormones, thyroid, or key nutrients.

Geviti Highlights

• Twice-Yearly Consistency: All 100+ markers tested each round, ensuring a more thorough recheck every six months.
• B12 & Progesterone: Direct measurement of vitamin B12 (rather than using a proxy like methylmalonic acid) plus progesterone testing for both men and women.
• At-Home Convenience: Option for lab draws at home, which Function Health does not offer.
• Follow-Through: Built-in support to address abnormal results immediately, including hormone therapy or peptide prescriptions.

Which Health Optimization Program Is Right For You?

1. If You Want Just Testing Without Follow Up
   Function Health’s panels are simple and straightforward. If all you want is numbers, Function may be the right choice. Just remember that it doesn’t come with in-house treatment or appointments with a specialist.
   
2. If You Want Actionable Data and Regular Check-Ins
   Geviti’s approach aims to give you an in-depth look at 100+ biomarkers twice a year, then put a plan into motion right away. Whether it’s adjusting hormones, adding personalized supplements, or introducing peptides, you’ll have a dedicated team to guide you through every step. Telehealth services like Geviti provide access to a wide range of lab tests that are often difficult to obtain through traditional healthcare channels, empowering you to take control of your health with detailed biomarker insights.
   
3. If Convenience Matters
   Geviti’s at-home testing can be a game-changer for those with an on-the-go lifestyle. From at-home testing to virtual appointments, Geviti comes to you. If you’d prefer a more traditional lab visit experience, Function Health may be best as members are required to visit a Quest Labs location (however, Geviti members also have the option to simply request a requisition and perform the blood draw from a Quest or LabCorp).
   
4. If you want custom supplements
   Geviti looks at your biomarkers and creates a custom supplement plan to address things like nutrient deficiencies, hormonal imbalances, gut issues, and more. Plus, Geviti partners with Xymogen, one of the most well-researched supplement companies, to provide the best quality supplements to their members. Members can purchase their supplement plan right from the Geviti app.
   
5. If Cost is Your Top Priority
   Function Health’s $365 annual membership stands out for budget-focused consumers who mainly want data. However, by bundling testing, consultation, and treatment all in one membership, Geviti might be more cost-effective in the long run, especially if you’d otherwise pay separate doctors and specialists for guidance.
   

Conclusion

Both Function Health and Geviti are major contenders in today’s health optimization market. Function Health provides a broad suite of biomarkers but leaves most treatment and follow-up in your hands. Geviti, on the other hand, offers a robust system that tests all biomarkers twice a year and provides direct interventions, comprehensive coaching, and the ease of at-home labs and specialty testing.

When it comes to health and longevity, relying on just one test is not sufficient—ongoing, comprehensive testing is essential for accurate assessment and long-term results. A robust, ongoing health optimization program may be the key to preventing chronic illness and boosting energy. Individuals are increasingly embracing data-driven programs that help them feel their best at every stage of life.

If you’re looking for an all-in-one solution that not only delivers lab results but also turns those results into a real plan for longevity, Geviti is likely the better fit.
