Function Health: preventive health membership with 160+ lab tests

Function Health is a preventive health service based on an annual membership that provides access to 160+ lab tests, designed by doctors, to detect early indicators of thousands of diseases. The approach focuses on continuous tracking of biomarkers over time, with explained results and a personalized action plan.

Testing and tracking

The membership includes 160+ annual lab tests, with testing done at least twice a year: an initial round of 100+ tests at the annual visit and a second round of 60+ tests three to six months later. The goal is to monitor changes in biomarkers related to hormones, thyroid, heart, metabolism, nutrients, metals, autoimmunity, liver, and electrolytes. The tests cover areas such as hormones and thyroid (16 biomarkers), cancer and silent risks (34 biomarkers, including the Galleri® multi-cancer test), heart and metabolic (18 biomarkers), aging (34 biomarkers), and mental health and focus (20 biomarkers).

The company states that additional tests for any biomarker can be requested on demand, at a member-only cost. Results are delivered with explanations prepared by doctors and a full clinical summary, plus personalized action items.

Access to tests and blood draws

Testing can be done at 2,000+ partner labs in the United States or via an at-home blood draw with a licensed specialist, who can come to your home or office. The company also offers access to imaging tests (MRI and CT) and Alzheimer's and brain function tests, as well as mold reactivity testing, as detailed on its site.

Price and coverage

The membership costs $365 per year, equivalent to $1 per day, and is eligible for payment with HSA/FSA funds. No health insurance is required. The site notes that this price contrasts with what a similar approach outside the membership could cost, which it estimates at up to $15,000.

Manson (chief of Preventive Medicine at Brigham & Women's Hospital and professor at Harvard), Andrew Huberman (professor of Neurobiology at Stanford School of Medicine), Toby Cosgrove (former CEO of Cleveland Clinic), Daniel Sodickson (chief of Innovation at NYU Langone), Azra Raza (oncologist and professor at Columbia University), Eddie Chang (professor and chair of Neurosurgery at UCSF), Luis A.
