Function Health Review: Cost, Biomarkers & Alternatives

Function Health costs about $365 per year, reduced from its earlier $499 price. The membership covers 160+ lab tests across the year — roughly 100+ markers at your annual visit and a 60+ marker follow-up about six months later — plus clinician review and a personalized action plan. Function also runs a periodic two-year offer (around $499 for two years, or ~$250/year). Testing in New York and New Jersey costs more due to state lab regulations. These are advertised estimates that change; confirm current pricing directly with Function before you join.

It depends on whether you value breadth and interpretation over lowest cost per marker. A single cash-pay wellness panel runs roughly $90-$130, so Function's $365/year is more upfront — but it bundles 160+ markers a year, two draws, clinician flagging, and a tracking dashboard. If you only want a basic annual panel, self-ordering through a direct-access lab is cheaper. If you want a wide, repeated, interpreted picture, a membership can win on cost-per-result. Compare the math against your goals before deciding.

Function Health does not run its own lab. Blood draws are processed through Quest Diagnostics, which is CLIA-certified and CAP-accredited — the same federal quality standards and gold-standard accreditation that govern conventional clinical labs. The accuracy of the underlying results is therefore comparable to standard Quest testing. The value Function adds is selecting the panel, ordering it without a doctor visit, having clinicians review results, and presenting them in a trackable dashboard. This is information, not medical advice.

Function Health states that its membership is HSA and FSA eligible, meaning you may be able to pay with pre-tax dollars. Eligibility depends on your specific plan and administrator, so confirm with both Function and your HSA/FSA provider before assuming the membership qualifies. Paying pre-tax can lower the effective cost, but the exact savings depend on your tax situation. Verify before you buy.

The closest membership alternatives are SuperPower (about $199/year, ~$399 in NY/NJ, one comprehensive 100+ marker annual panel through Quest) and InsideTracker (membership about $149/year, with blood-test plans like Ultimate priced separately). If you only want occasional labs, self-ordering through Quest Health, Labcorp OnDemand, or Ulta Lab Tests is cheaper per panel. The right pick depends on how many markers you want, how often you test, and whether you value clinician review. Prices change — confirm with each provider.

No. Function Health is a direct-to-consumer service: you join, get a requisition, and visit a Quest Diagnostics location for your draw without needing your own physician to order the tests. Function's clinicians review the results and flag issues, but the platform is designed for self-directed, preventive testing rather than diagnosis or treatment. Anything flagged should be discussed with a licensed clinician. This is general information, not medical advice.
