Function Health is a consumer longevity and preventive-health membership that runs 100+ lab biomarkers twice a year through Quest Diagnostics, adds clinician review, a biological age calculation, and an AI health companion via a web and mobile dashboard. As of this catalog Function Health does not publish a public or partner developer API; member data is accessed through the member dashboard, PDF export, in-product Connected Apps (wearable sync), and an opt-in ChatGPT app that shares a high-level summary of results.
