The best lab test membership for longevity tracking depends on your specific priorities, but Function Health is widely considered the top overall choice for most people seeking a balance of breadth, longitudinal tracking, and physician oversight [5][7].
However, other services excel in specific niches:
| Service | Best For | Key Details |
|---|---|---|
| Function Health | Overall best value & breadth | $499/year; 160+ biomarkers tested twice annually; includes physician review, trend dashboard, and on-demand testing [5][11] |
| Bloody Good Test | Maximum biomarker depth in one draw | Covers 100 biomarkers including all evidence-based longevity markers (fasting insulin, HbA1c, ApoB, hs-CRP, full lipid panel, thyroid) in a single draw [1] |
| My Vital Metrics | UK/Europe users & DEXA integration | “Outlive Your Years” bundle; £75/month for 7 months; includes 3 DEXA scans + full health screen based on Dr. Peter Attia’s protocol [3] |
| InsideTracker | Personalized interventions & coaching | Focused on longevity/recovery biomarkers (ApoB, hs-CRP, IGF-1, sex hormones); offers diet/supplement/exercise plans and easy re-testing [2][4][6][8] |
| Wild Health / Era Health | Physician-guided personalization | Hands-on medical oversight with unparalleled customization for budget-conscious users seeking deep personalization [6] |
Key longevity biomarkers any top membership should include: ApoB, Lp(a) (once), hs-CRP, HbA1c, fasting insulin, full lipid panel, and thyroid function [1][9].
If you want the most comprehensive single-draw test, choose Bloody Good Test [1]. If you prioritize ongoing tracking with physician oversight and value, Function Health is the top pick [5][7]. For UK/EU residents needing DEXA scans, My Vital Metrics is ideal [3].
