General Retesting Guidelines
| Situation | Frequency |
|---|---|
| Healthy baseline maintenance | Once a year |
| Actively changing diet/exercise | Every 3-4 months |
| Managing a health condition | Every 1-3 months (doctor-guided) |
| After starting new supplements | 6-8 weeks later |
Key Tip
Track trends over time rather than single snapshots — this is where services like InsideTracker and Function Health add real value with longitudinal tracking.
Always consult your doctor for personalized advice, especially if managing chronic conditions. Overtesting without context can lead to unnecessary anxiety.
