A tiny hero for an older sibling.

If your family has a child with a life-threatening disease that may be treated with a cord blood transplant, you can choose to save your baby's umbilical cord blood for a biological sibling. The saved cord blood will be stored in a public cord blood bank.

Here are a few things to keep in mind when considering sibling cord blood donation:

  • The cord blood bank determines your final eligibility for sibling-directed donation programs
  • Some cord blood banks may charge your insurance company for this service. Others may offer this service at little or no cost
  • A fee will be charged to your insurance company when the cord blood that you stored is used for your other child's transplant
  • Siblings should have the same biological parents

If your family is eligible, the cord blood bank will provide a cord blood collection kit to take to the delivery hospital. The kit will come with instructions about sending the collected cord blood to the cord blood bank for processing and storage.

Below is a list of cord blood banks that will collect and store umbilical cord blood for eligible families within the United States. Doctors and families can contact these cord blood banks for more information. Cord blood banks should be contacted as early as possible in your pregnancy.
