Cord Blood Banking
What it is and whether it is right for your family
What Cord Blood Is Used For
Umbilical cord blood contains stem cells that can treat certain cancers, blood disorders, and immune conditions. After the baby is born and the cord is clamped, blood that remains in the cord and placenta can be collected and stored. This blood is rich in hematopoietic stem cells, which are used in transplants as an alternative to bone marrow.
Public versus Private Banking
With public banking, the cord blood is donated to a public bank and becomes available for anyone who needs a match. There is no cost to you. With private banking, the blood is stored exclusively for your family's use at a private facility. Private banking costs an initial fee of roughly $1,500 to $2,500 plus an annual storage fee of $100 to $200. Private banking is rarely covered by insurance.
Who Actually Needs Privately Banked Blood
The chance that a family will ever need their privately banked cord blood is very low, estimated at less than 1 in 2,500. The blood is primarily used for the child who donated it, and many conditions that are treatable with stem cells can also use stem cells from other donors. Private banking is most often recommended when a family already has a child with a condition that can be treated with stem cells, or when there is a known genetic condition that could benefit from a future transplant.
What to Decide
If you are interested in public donation, discuss it with your care provider by week 34 of pregnancy. Not all hospitals participate, and the collection process requires advance arrangements. If you are considering private banking, research companies carefully and understand the fee structure. Some parents choose private banking for peace of mind even when the statistical need is low. Others prefer to donate publicly so the blood can help someone else. Neither choice is wrong. The important thing is to decide before labor begins.
Delayed Cord Clamping
Delayed cord clamping, waiting at least 30 to 60 seconds before cutting the cord, is now standard practice because it benefits the baby by increasing blood volume and iron stores. Delayed clamping can be done alongside cord blood collection using methods that do not interfere with the baby's blood supply. If cord blood banking is important to you, confirm with your provider that both delayed clamping and collection can happen together.
