Quick answerFunction Health is a $365-a-year membership that bundles 160+ lab tests, drawn at Quest or at home, with clinician review in one dashboard. It fits people who want broad testing twice a year. It costs more up front than one or two single tests.

We have not ordered from Function Health. This page summarizes what its own public pages say, checked 2026-10-14. Details change, so confirm at checkout.

The facts from its site

Tests160+ lab tests a year. Start with 100+ at your first visit, then 60+ about 3 to 6 months later.
Where you drawQuest, 2,000+ locations, or a licensed specialist at your home or office.
ResultsOne dashboard with explanations, action items, and a clinician summary. You can share results with your doctor.
Extras listedAdd MRI and CT, the Galleri multi-cancer test, and Alzheimer's and mold reactivity testing. Add-on prices are not stated on the page we read.

At $365 for 160+ tests, the membership works out to about $2.30 per test counted by its own figure. Compare that with a single panel only if you would actually use most of the tests.

  • Clinician review of every result, per its site.
  • Home draw option for people who dislike lab visits.

Check before you buy

  • The page we read did not state which states are not served.
  • On-demand tests beyond the plan carry a member-only cost the page does not list.
  • Broad panels produce more borderline results. Plan to discuss them with your own clinician.
  • Cancel and renewal terms: read them before you pay for a year.

Who it fits

  • You want a wide baseline and a repeat test within the year.
  • You want one place for results and explanations.

Who may want a different option

  • You only want one or two tests. A single-test seller costs less.
  • You want a specific heart-risk test. Check that the biomarkers you care about, such as ApoB and Lp(a), are in the plan.
