Blood Biomarker Retesting Frequency
Here are some general guidelines and services to consider:
Recommended Frequency
- Annual baseline testing – good for most healthy adults
- Every 3-6 months – if managing a chronic condition or optimizing specific health goals
- After major lifestyle changes – new diet, medication, or exercise program (retest in 6-8 weeks)
Recommended Services
At-home testing:
- Everlywell – convenient panels mailed to you, good for periodic check-ins
- Function Health – comprehensive 100+ biomarker panels, designed for frequent tracking
- Inside Tracker – popular for performance optimization, includes personalized recommendations
Lab-based testing:
- LabCorp or Quest Diagnostics – widely accepted, often covered by insurance
- Life Extension – affordable panels without a doctor's visit
Subscription/ongoing monitoring:
- Levels (metabolic health) – pairs with continuous glucose monitors
- Marek Health – good for people wanting physician-guided optimization
Key Advice
- Talk to your doctor before setting a schedule, especially if you have health conditions
- Insurance typically covers annual labs
- More frequent testing makes most sense when actively changing something (diet, supplements, medications)
