Blood Biomarker Retesting Frequency
Great question! Here are general guidelines and some helpful services:
General Recommendations
- Annual baseline panel – minimum for most healthy adults (standard with your doctor)
- Every 3-6 months – if managing a chronic condition, optimizing health, or making significant lifestyle changes
- Every 6 months – good middle ground for proactive health tracking
Recommended Services
For At-Home Testing:
- Everlywell – convenient kits, good for periodic checks on specific markers
- Function Health – comprehensive panels (100+ biomarkers), designed for twice-yearly testing
- InsideTracker – great if you're tracking fitness/longevity markers, recommends retesting every 3-6 months
For Clinical Testing:
- Quest Diagnostics or LabCorp – reliable, widely accepted by insurance
- Marek Health – good for optimization-focused panels with physician oversight
Key Factors That Affect Frequency
- Age (older = more frequent)
- Family history
- Recent diet/medication changes
- Fitness goals
- Managing conditions like diabetes or thyroid issues
Bottom Line
Function Health's twice-yearly model is a solid standard for proactive health monitoring, while working with your primary care physician annually at minimum.
Always consult your doctor about what's right for your specific situation.
