Function Health costs $365 a year for 160+ lab tests across two draws.
It is a biomarker-testing membership, not a doctor service. The real alternatives split into two camps: other testing memberships, and skipping the membership model entirely.
Testing memberships
Superpower: $349/year, 150+ biomarkers across two blood draws at 2,000+ Quest locations, with an AI layer and care team to build a protocol from your results.
InsideTracker: biomarker subscription with tiered panels and a long track record in the quantified-self space.
The membership-free route
Doctor-ordered labs: a primary care clinician or telehealth doctor can order the specific tests your history actually calls for, usually covered by insurance, often for a fraction of a broad panel's cost.
Direct-to-consumer labs: Quest and Labcorp both sell individual tests online without a doctor visit in most states.
The catch with any panel: 160 numbers without interpretation are noise. Before buying a membership for the data, plan for who will explain it. Pymander's AI doctor can walk you through any lab result by text, free, 24/7, and tell you which results genuinely need a doctor's eyes.
