Best Lab Test Memberships for Longevity Tracking
Top Recommendation: Function Health
- ~$499/year for 100+ biomarkers tested twice annually
- Co-founded by longevity-focused physicians
- Covers hormones, metabolic markers, inflammation, organ function, and more
- Clean dashboard with trend tracking over time
- Strong value for the comprehensiveness offered
Other Strong Options:
Inside Tracker
- Focuses on biological age and actionable lifestyle recommendations
- Pairs well with wearable data
- Good for people who want personalized optimization plans
Marek Health
- Better for those wanting physician oversight and hormone optimization
- More clinical/medical approach
Ulta Lab Tests (à la carte, not membership)
- Best if you want to customize exactly what you test without a subscription
What to Look For:
- Key longevity markers: ApoB, hsCRP, HbA1c, IGF-1, homocysteine, testosterone, Lp(a), thyroid panel
- Trend tracking over time (critical for longevity monitoring)
- Physician review options
My top pick is Function Health for most people because of the breadth of testing and the longevity-specific focus at a reasonable annual cost. Worth comparing with Inside Tracker if behavior coaching matters more to you.
