Vitals Vault starts with 120 biomarkers. 2026 comparison # Function Health vs Vitals VaultDon't buy your follow-up before you know what needs follow-up. Function Health says 160+ tests annually, but that is not 160 unique biomarkers. It is 100+ tests first, then a 60+ mid-year follow-up that repeats prior markers. Vitals Vault gives the deeper baseline first: 120 for $99, 140 for $199, or 160 for $399. Then follow up from your actual results: repeat Essential for $99, or order only the Quest markers you need from $14.99.

It is whether you should buy a prepackaged follow-up before your first results show what deserves follow-up. ### More upfront data Start with 120 biomarkers for $99, or choose 140/160 upfront before making any follow-up decision. ### No subscription $99-$399 one-time pricing. Three full Essential draws are $297; four are $396. ### More flexibility Retest the full Essential panel for $99, or add targeted Quest follow-ups from $14.99 when only a few markers matter. ### More support Use the live site support widget, email the Vitals Vault concierge team, and ask Neo about your results. ### More ownership Export your data, upload past labs, and keep your health history portable instead of locked to one program. [Compare all panel options](https://www.vitalsvault.com/checkout) Same Quest network · No subscription · HSA/FSA eligible When Function Health may make sense Function Health may fit people who specifically want a recurring annual testing membership with a standardized initial panel and a built-in 60+ test follow-up later in the year. But choose Vitals Vault when Vitals Vault is stronger if you want the bigger upfront baseline, result-driven follow-up testing, live support, full data control, and no recurring commitment. ### Baseline first. Follow-up second. Start with 120 biomarkers for $99. Then use your actual results to decide whether you need a full retest, a few targeted Quest markers, or no follow-up lab order yet.

The clearest reason is control. Function Health is a $365/year membership built around a 100+ Annual Test and a prepackaged 60+ Mid-Year follow-up. Vitals Vault starts with a one-time Quest-based baseline: $99 for Essential with 120 reported biomarkers and clinical ratios, $199 for Advanced with 140, or $399 for Max with 160. Then your actual results guide the next step: retest the full Essential panel for $99, or order targeted follow-up biomarkers starting at $14.99. Function Health is advertised at $365/year. Vitals Vault is one-time: $99 for Essential with 120 reported biomarkers and clinical ratios, $199 for Advanced with 140, or $399 for Max with 160. If you want follow-up testing, another full Essential panel is $99, so three Essential draws are $297 and four are $396. Targeted follow-up biomarkers can start at $14.99. HSA/FSA eligibility can depend on your plan. Every plan includes a 90-page Functional Health Report that evaluates each biomarker against two sets of ranges: the standard lab range (are you sick?) and a functional optimal range (are you actually healthy?). Here’s the difference that matters: Function Health told you your TSH of 4.0 was “normal.” A functional medicine practitioner knows anything above 3.0 correlates with early thyroid underperformance — and you’ve been blaming the fatigue on sleep. Your fasting glucose of 94 passed their screen. Our TyG Index flags the insulin resistance behind it a decade before your A1c moves. Your ferritin of 25 was “within range.” But paired with your hs-CRP and dropping iron saturation, it’s a pattern of chronic inflammation no standard report would connect. The report scores 13 body systems, computes 34–50 clinical ratios that don’t exist on your Function Health dashboard, and gives you an Action Plan with specific supplement recommendations, dosages, safety notes relative to your medications, and PubMed-cited evidence — not “eat more vegetables.” Yes — and this is one of the biggest differences. Function Health gives every member the same ~100-biomarker panel regardless of whether you’re a 28-year-old woman with PCOS symptoms or a 55-year-old man on statins with a family history of heart disease. Vitals Vault’s Custom Panel Builder is an AI clinical consultation that conducts a multi-turn interview about your symptoms, medications, family history, and lifestyle — the kind of workup you’d get at a $10,000 concierge medicine practice. It builds differential hypotheses about what’s driving your symptoms (thyroid dysfunction? insulin resistance? chronic inflammation?), then assembles a panel that tests those specific hypotheses. You see exactly why each test was selected, which clinical findings it investigates, and the confidence level for each hypothesis. The system runs deterministic medication-depletion rules (statins → CoQ10, metformin → B12, PPIs → magnesium), family-history risk panels, and then layers an LLM consultation on top. No other blood testing service — not Function Health, not InsideTracker, not Superpower — offers anything like this. They give everyone the same tests. We build yours. Function Health is an annual testing membership: 100+ lab tests first, then 60+ tests halfway through the year to see what changed. That is an annual count across two testing moments. The 60+ follow-up is not the same as 60 new unique biomarkers, and it is not a custom panel selected because your first results showed a specific issue. If you counted repeat testing the same way, two Vitals Vault Essential panels would be 240 test events for $198. But the clearer comparison is simpler: 120 upfront for $99, then choose whether you need a full retest or only a few targeted markers. Yes. Vitals Vault is built around a broad Quest-based add-on catalog, so you can go beyond the core panel with targeted testing for specific symptoms, goals, or follow-up questions. Targeted follow-up biomarkers can start at $14.99, with availability and pricing varying by test. Your report is powered by a clinical intelligence engine built on a 3-million-node knowledge graph (HPO, SNOMED, UMLS, and functional medicine ontologies). It doesn’t just flag individual markers — it detects compound risk patterns the way a functional medicine doctor thinks. For example: elevated LDL + elevated hs-CRP + family history of heart disease triggers a “Cardiac Triple Threat” pattern that exponentially increases your risk beyond what any single number shows. High glucose + high triglycerides + low HDL triggers a “Metabolic Syndrome Pattern.” The engine evaluates your results against your 15-section health profile (medications, family history, symptoms, diet, sleep, stress, supplements, and more), uses UMLS/RxNorm to understand drug interactions with your current medications, and detects worsening trends across past labs. All protocols were developed with Dr. Rob Lufkin (Clinical Professor, USC Keck School of Medicine, 200+ peer-reviewed papers). PocketMD, your AI health assistant, reads every report with you and can hand you to a clinician. This isn’t a chatbot — it’s a physician-designed clinical engine that thinks in constellations, not isolated numbers. Still on the fence?
