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.
The smarter sequence:
baseline first, follow-up second.
100+ initial tests
Function FAQ: Annual Test
60+ mid-year follow-up
Preset retest, not 60 new unique markers
Follow-up bought upfront
Before first results are known
$365/year membership

120, 140, or 160 upfront
One baseline draw
Follow up after results
Order based on your actual results
Full Essential retest: $99
Run it again only if needed
Targeted Quest markers from $14.99
Buy only what you need
More signal upfront. More control afterward.
Function’s 160+ annual count combines two testing moments: 100+ tests upfront, then 60+ tests halfway through the year. Vitals Vault keeps the decision cleaner: get a broad baseline first, then use your actual results to decide what comes next. Full Essential retest: $99. Targeted Quest follow-ups: from $14.99. Less annual-count math.
Upfront baseline biomarkers
Quick verdict
Choose Function Health if you want to buy an annual testing structure upfront: 100+ tests first, then a prepackaged 60+ mid-year follow-up.
Choose Vitals Vault if you want the broad baseline first, then follow-up testing based on what your results actually show.

FAQ
Real questions, real answers
Vitals Vault offers more biomarkers (160+ vs 100+), a 90-page report vs a 1-page summary, biological age tracking, and costs $99 with no subscription. Function Health costs $499/yr with auto-renewal. Both use accredited labs, but Vitals Vault delivers significantly more value per dollar.
Function Health auto-renews annually at $499. Vitals Vault is a one-time purchase with no subscription and no auto-renewal.
Vitals Vault starts at $99 (Essential), $199 (Advanced), or $399 (Max) as one-time purchases. Function Health costs $499/yr with auto-renewal. Even the Max plan costs less than one year of Function Health.
Function Health provides a 1-page summary with basic reference ranges. Vitals Vault’s 90-page Functional Health Report includes system-by-system analysis, optimal (not just normal) ranges, trend tracking, and personalized action plans.
Yes, Vitals Vault is fully HSA/FSA eligible. Function Health does not currently accept HSA/FSA payments.
Function Health includes two blood draws per year in their $499 membership, but the second "follow-up" draw only repeats basic panels like CBC, CMP, and urinalysis. It does not re-test the advanced markers — hormones, inflammation, micronutrients — that customers actually care about. You pay upfront for both draws, but the second one delivers limited value. Vitals Vault tests all your biomarkers in a single comprehensive draw for $99–$399 with no subscription.
