100 Biomarkers, No Doctor’s Visit
Function Health and the at-home testing boom — what full-panel blood work actually tells you.

For most of medical history, you got blood work when a doctor ordered it. Now you can order 100+ biomarkers yourself. Function Health — co-founded by Dr. Mark Hyman — runs 160 tests across two panels a year for $365, with AI-generated reports, and in April 2026 it acquired a mobile-phlebotomy company so the draw can happen at your kitchen table.
Why it matters
It moves you from “sick care” to baselines. Tracking 100 markers over time catches drift — a creeping cholesterol, a sliding vitamin D — years before symptoms. That’s the same predict-don’t-react logic driving the whole consumer-health shift.
The honest caveat: more data isn’t automatically more health. Out-of-range values are common and often harmless, and a wall of red flags can drive anxiety and unnecessary follow-ups. Full-panel testing is most useful with a clinician who can tell signal from noise — not instead of one.
How to do it well
A comprehensive at-home panel
A full-biomarker baseline you can repeat — the point is the trend line, not a single snapshot.
