Donating Cord Blood
Immediately after the birth of your baby, the umbilical cord is clamped and cut. If you choose to collect your cord blood for donating or banking for personal use, another clamp is placed 8 to 10 inches away from the first, then the isolated section is cut and the cord blood is collected.
Most hospitals routinely collect cord blood at birth, with the consent of the parents, since it is relatively convenient and birth is the only time it is possible to do. St. Luke's participates in collecting cord blood donations for the St. Louis Cord Blood Bank.
