If blood is not flowing out of your finger, try these steps:
1. Wash your hands with soap and massage your hands under running warm water for a good while.
2. Increase your heart rate by windmilling your arms. This increases your blood circulation and makes sample collection easier. You can further increase your heart rate by jogging in place.
3. Try collecting the sample from another finger.
