Function Health alternatives: cost, what it tests, and paying per test instead

Only if it is in the mid-year subset. Function's second draw repeats a fixed list of markers — lipids, hemoglobin A1c, hs-CRP and insulin among them — on Function's schedule, roughly six months after the annual draw. The markers people most often want to recheck after a change are tested once a year: ApoB, vitamin D, ferritin, TSH, testosterone, estradiol, homocysteine, cortisol, DHEA-S and magnesium. A recheck of any of those in 8–12 weeks is a paid add-on or the next $365 annual draw.

Per test, that recheck is the clearest case for not joining: an ApoB, vitamin D and ferritin follow-up at TestWell is about $104 including the $6 fee, drawn at the same Quest site, results in 1–3 days, whenever you want it. The membership prices the first look well; the follow-up is where it costs you.

Function Health costs $365 a year, charged annually and marketed as $1 a day. That buys 160+ lab tests across two blood draws — an annual draw of roughly 115 markers and a mid-year draw that repeats about 60 of them — plus clinician review of every result and a written protocol. Add-ons (MRI and CT scans, Galleri, extended panels) cost extra. In New York and New Jersey a state fee is charged at the facility on the day of the draw.

There is no monthly plan and no single-test option: $365 is the floor. The membership is HSA/FSA eligible. Verified on functionhealth.com/pricing on 2026-10-22.

The annual draw covers heart (ApoB, Lp(a), NMR LDL particle number and size, hs-CRP, a standard lipid panel), thyroid (TSH, free T4, free T3, TPO and thyroglobulin antibodies), autoimmunity (ANA with pattern and titer, rheumatoid factor), a CBC with differential, hormones (testosterone, estradiol, FSH, LH, prolactin, SHBG, DHEA-S, AMH for women, PSA total and free for men), metabolic markers (glucose, HbA1c, insulin, leptin, uric acid), a comprehensive metabolic panel, liver and kidney function, lead and mercury, nutrients (ferritin, iron and TIBC, magnesium, zinc, vitamin D, homocysteine, MMA, omega-3 and omega-6 fatty acids), amylase and lipase, blood type and a complete urinalysis.

About 100 of those are measured directly; 14–15 are calculated from other results (LDL, eGFR, ratios, biological age). The mid-year draw repeats the core ~60: CBC, CMP, lipids, HbA1c, insulin, hs-CRP and the urinalysis.

If you will use the whole panel twice a year, yes on price: $365 for two draws of 100+ markers works out to roughly $3 per marker, cheaper than buying the same breadth à la carte anywhere, and the clinician write-up is included. Members who read the results carefully and act on the protocol get real value.

If you want a handful of specific answers — a lipid panel and ApoB, thyroid, vitamin D, testosterone, an A1c — the membership is paying for 100 markers to get the five you care about. Those five cost about $120 à la carte at the same Quest or Labcorp draw site, with results in 1–3 days and no renewal next year. Reviewers also note the clinician plan can take three to four weeks to arrive after results post, while the results themselves start within 48 hours.

Yes. Function Health is an established, venture-backed company whose draws are performed by Quest Diagnostics at 2,000+ locations in 48 states, with licensed clinicians reviewing results. The common complaints in public reviews are about the wait for the written plan and the annual-commitment model, not the lab work itself.

Superpower ($199 a year, one draw of 100+ biomarkers, AI protocol, 41 states + DC, $399 in NY/NJ) is the closest membership alternative — see our Function Health vs Superpower comparison. InsideTracker sells a smaller membership-plus-panel product aimed at athletes.

If you do not want a membership at all, à la carte marketplaces order the same tests at the same labs one at a time: TestWell (from $14.99 a test, the General Wellness Panel's four physical-exam tests for $49.99, Quest or Labcorp, NY/NJ via BioReference), Quest's own QuestHealth and Labcorp OnDemand (single-lab, higher list prices), and others we compare on this site. The right pick depends on how many markers you actually want and how often.

Yes — the membership is HSA/FSA eligible, and Function's site promotes paying with HSA/FSA funds. TestWell orders are also HSA/FSA eligible, with an itemized receipt that lists CPT codes for each test, which is what most administrators ask for.

Function occasionally runs limited promotions (a "Function Day" offer appeared on its pricing page in October 2026) and referral credits for existing members; it does not publish standing discount codes, and most "promo code" pages online are affiliate links to the regular $365 price. The reliable way to pay less is to not buy the membership: order the specific tests you want à la carte and skip the ones you don't.
