Quick Rule of Thumb
| Situation | Frequency |
|---|---|
| Healthy maintenance | Annually |
| Active optimization | Every 3-6 months |
| Managing illness | As directed by doctor |
Always consult your doctor about which biomarkers matter most for your specific health goals — frequency should match what you're actually tracking and changing.
