Function Health
Compared with Superpower, WHOOP Advanced Labs and InsideTracker: see the comparison →
Function Health offers the broadest DTC blood biomarker panel on the market — 160+ tests covering everything from standard lipids to multi-cancer screening, heavy metals, Alzheimer's markers, and more. Unlike a standard annual physical that runs 10–20 markers, Function gives you a complete picture twice a year through 2,000+ Quest locations. Results come with clinician-reviewed explanations and a personalized protocol — no doctor's visit required.

Access to add-onsAlzheimer's (p-Tau217), mold reactivity, MRI & CT scans
160+ biomarkers across 6 functional categories is best-in-class for a DTC membership product. Galleri multi-cancer screening is available, but as a paid add-on, not part of the membership. The only reason this isn't a 10: the panel doesn't include microbiome, continuous glucose, or integrative metabolomics — categories that require separate platforms.

Quest labs are gold standard. The medical advisory board is credentialed — not figurehead appointments. Clinician review of every result is a meaningful safety layer. A point deducted because a number of the "aging" and predictive markers remain early-stage in terms of clinical utility, and the company's marketing sometimes outpaces the evidence base for those specific tests.

Access to MRI/CTYes — at member pricing through Ezra partnership
Function's actionability layer is the strongest in the DTC space. You get a personalized protocol after each test, results with clinical context, and a clinician who flags anything worth following up on. The trend-tracking dashboard and ability to upload historical results make it possible to see your biology across years, not just a single snapshot. Slight deduction: no live care team access, so follow-up questions go to an AI assistant rather than a clinician directly.

Annual price$365/year
Cost per biomarker~$2.28/marker for 160 markers tested 2×/year
Galleri standalone pricePaid add-on, not included in membership
Equivalent concierge medicine$5,000–15,000/year for similar biomarker depth
HSA/FSAYes — eligible
Add-onsMRI, CT scans, and specialty tests cost extra
At $365/year for two draws, Function costs about $12 per reference marker, among the lowest in this group. The cost per biomarker is among the lowest in the industry. The reason this isn't an 8+: the membership model creates a recurring cost, add-ons layer on quickly, and access in NY/NJ is restricted. Not everyone needs 160 biomarkers twice a year — for some users, a cheaper targeted panel is more appropriate.

Lab network2,000+ Quest locations nationwide
At-home draw optionYes — via Getlabs mobile phlebotomy (additional cost)
Results turnaroundTypically 24–72 hours after blood draw
App/dashboardiOS and Android — highly rated
Setup frictionEasy — schedule, draw, results in app
The breadth of Quest locations makes access simple for most of the US. The app is polished, the results are beautifully organized by category, and the onboarding is smooth. 75M+ results delivered signals operational maturity. The only meaningful friction: New York and New Jersey residents have restricted access to certain tests due to state regulations.
What makes Function different
Most annual physicals test 10–20 markers and tell you whether you're in range. Function tests 160+ and tells you where you're trending — with a protocol for what to do about it. Galleri multi-cancer early detection is available as a paid add-on: it screens for 50+ cancer types from a single blood draw. For the price, no other DTC platform comes close to this breadth.
Pros & cons
What works
+ 160+ biomarkers — best-in-class depth for DTC
+ Galleri multi-cancer screen available as a paid add-on
+ Every result clinician-reviewed and flagged if abnormal
+ 2,000+ Quest lab locations — easy scheduling
+ Personalized protocol after each test cycle
+ HSA/FSA eligible
+ Heavy metals, mold reactivity, ApoB, Lp(a) included
Watch out for
− NY and NJ residents have restricted test access
− MRI, CT, and specialty tests are add-ons (extra cost)
− No live care team — AI assistant for follow-up questions
− Membership model means recurring annual cost
− Some predictive markers still have limited clinical utility
Bottom line
MYM verdict
If you want the most comprehensive at-this-price blood biomarker platform available DTC, Function is the answer. The breadth is unmatched, the clinical infrastructure is real. It's not perfect — NY/NJ restrictions are frustrating, and the add-on model can escalate costs — but as a baseline for anyone serious about understanding their biology year over year, nothing else competes at this price point.
