I ran a marathon recently. How long should I wait before collecting?

After extreme endurance exercise (marathon, triathlon, ultra-marathon, very intense HIIT workout), we recommend waiting 48 hours before collecting your OncuraKit sample. Extreme exercise causes release of miRNAs from skeletal muscle and other stressed tissues into circulation, and transiently elevates inflammatory miRNAs including miR-21. Within 24–48 hours of intense exercise, these miRNA levels return to your personal baseline. For routine daily exercise (30–60 minutes of moderate cardio, weight training, yoga), there is no need to wait — collect at any time in your normal exercise schedule.
