--- title: TestWell vs Function Health type: comparison url: "https://www.test-well.com/compare/function-health" competitor: Function Health competitor_url: "https://www.functionhealth.com" competitor_pricing_model: subscription testwell_per_order_fee_usd: 6 verified: 2026-09-05 --- # TestWell vs Function Health > Pick Function Health if you'll definitely test twice a year and want a fixed annual price ($365/yr). Pick TestWell if you want to pay only for the tests you actually need — typically 50-90% less for occasional testing. 160+ lab tests, twice a year, for a flat annual membership. Function Health is a membership: $365 a year (billed annually, marketed as $1/day) buys 160+ lab tests drawn twice a year at 2,000+ Quest locations, clinician review of every result, and a personalized action plan. It is built around whole-body, longevity-oriented testing rather than à-la-carte ordering — there is no way to buy a single test.

A licensed physician authorizes every TestWell order, but that review is not a visit — there is no call to walk through results unless you bring them to your own provider. - You can't get to a draw site. TestWell is venous-draw only at Quest, Labcorp and BioReference locations; we don't ship at-home finger-prick kits. - You live in Rhode Island — we can't serve it yet. New York and New Jersey orders route to BioReference locations only, which means fewer draw sites than Quest or Labcorp offer elsewhere. - You need insurance billed. TestWell is cash-pay; HSA/FSA cards work and every order gets an itemized receipt, but we don't file claims. - You need a specialty assay outside our catalog (~150 tests and 60+ panels). The big marketplaces list 1,000–2,000 SKUs; we deliberately don't. ## Frequently asked questions ### Are TestWell and Function Health using the same labs? When the lab partner is the same (Quest or Labcorp), the actual analysis is identical — same machines, same reference ranges, same CLIA-certified facility. The differences are price, ordering experience, and what's included. ### Can I switch from Function Health to TestWell mid-year? Yes. Lab tests aren't subscriptions you have to cancel — each order stands alone. If you've already paid for a year of Function Health, use what you've paid for, and order any additional tests through TestWell. ### Will my doctor accept TestWell results? Yes. Your results are CLIA-certified lab results from Quest or Labcorp — the same labs your doctor uses. You can download a PDF and bring it to any provider. ### Can I order a single test from Function Health? No — Function Health is membership-only. The $365 annual fee is the floor; there's no à-la-carte option. If you only need one or two tests a year, TestWell typically costs 50-90% less. ### Does Function Health include a doctor consult? Every result is reviewed by Function's clinicians with written insights and an action plan. TestWell's licensed physician authorizes the order, but there is no consult or written interpretation included by default. ## Sources - - Verified 2026-09-05; re-verified quarterly. - [All comparisons](https://www.test-well.com/compare) - [Browse tests](https://www.test-well.com/tests) --- Canonical page: https://www.test-well.com/compare/function-health Machine-readable catalog: https://www.test-well.com/api/catalog.json · MCP server: https://www.test-well.com/mcp · Overview for agents: https://www.test-well.com/llms.txt Prices are cash-pay, in USD, and include physician authorization; every order adds one flat $6 lab processing fee.
