Short answer
Function Health is $365 for the first year: 160+ lab tests over two draws at Quest labs, with a clinician summary. It is worth it if you want breadth and tracking. The four numbers with the strongest evidence, ApoB, Lp(a), HbA1c and hs-CRP, cost about $180 on their own. The renewal price isn’t published, and there are no refunds.
What you get
Function Health charges $365 a year, billed annually, and calls that the first-year price. For it you get 160 or more lab tests split across two blood draws at Quest Diagnostics locations, a written summary from a clinician, and an action plan in the app. It cut the price from $499 in November 2025.
The panel includes the markers we care most about: ApoB, Lp(a), hs-CRP, HbA1c and fasting insulin. Quest’s labs hold CLIA and CAP accreditation, the two main US lab quality marks.
What we couldn’t confirm
Function’s own footer describes $365 as the first-year membership price and says promotions apply to the first year, but no renewal price is published. New York and New Jersey members pay more, and the amount isn’t shown. Add-on tests and the at-home draw aren’t priced publicly, and the terms say no refunds for prior payments.
Function also bought a supplement-recommendation company and an imaging company, so expect upsells inside the app. That is why it sits as unclear, not a pass, on our tests page.
The cheaper way to the same numbers
If what you want is the handful of markers with the strongest evidence, you can order them yourself. At Labcorp OnDemand, ApoB is $51.75, Lp(a) is $36.75, HbA1c is $39 and hs-CRP is $51.75, about $180 in total with no membership. Quest sells similar tests per test plus a $6 physician fee.
Function makes more sense if you want the full breadth, want two rounds a year, and will actually act on what comes back.
