Function Health Membership
Function Health offers the most comprehensive biomarker testing available to consumers, covering 100+ markers including ApoB, Lp(a), and advanced hormones for a flat annual fee. While it requires a visit to a Quest lab (not a home finger-prick), the 'home device' aspect is the digital platform and kit management that makes high-level diagnostics accessible.
Ingredients & Purity
Uses standard clinical phlebotomy via Quest Diagnostics, which eliminates the 'insufficient sample' errors common with home finger-prick tests.
Scientific Evidence
All testing is performed by Quest Diagnostics, the world leader in diagnostic testing, ensuring gold-standard clinical accuracy.
Brand Transparency
Clear about what is tested, though the specific algorithms used for their 'insights' are proprietary.
Value Assessment
The $499 fee covers two sets of 100+ biomarkers per year. Individually, these tests would cost over $2,500 in a standard clinical setting.
Why Not Alternatives?
Traditional doctors rarely order this level of preventative testing (like full heart health or nutrient panels) without existing symptoms. Compared to InsideTracker or Life Extension, Function provides 3-4x the number of biomarkers for a lower total cost.
