How a blood sample is processed?

Blood Sample Handling and Processing: Complete gel barrier formation (gel barrier tubes) is time, temperature and G-force dependent. In general, for a horizontal, swing-bucket centrifuge, the recommended spin time is 10 minutes. NOTE: Gel flow may be impeded if chilled before or after centrifugation. Tubes should remain closed at all times during the centrifugation process.
