ND, United States
North Dakota does not have any state legislation around cord blood education, but their Dept. of Health has officially adopted the educational materials from Parent's Guide to Cord Blood Foundation.
- If I banked privately for one child, do I need to do it for additional children?
All the reasons that you banked for the first child are still valid for additional children.
1. If you want the baby to have the option of using his/her own cells, then you need to bank them.
2. If you are banking to cover siblings, then the ability to use cord blood from one child for another depends on whether they have matching HLA type. Two full siblings have a 25% chance of being a perfect match, a 50% chance of being a half match, and a 25% chance of not matching at all. For a cord blood transplant, donor and patient must match at 4 out of 6 (67%) HLA types. The more siblings with banked cord blood, the more chance that they cover each other for possible transplants or other therapies for which sibling stem cells are accepted.
Odds of sibling match are based on haplotype inheritence: that the child will receive 3 HLA types as a group from each parent.
- Once we have stored cord blood for our family, how long should we keep it?
- Indefinitely. From an economic perspective, it does not make sense to invest in the up-front processing fee and pay for years of annual storage, and then throw out the investment. That would be like buying life insurance and then cancelling it because you have not died yet. Especially given that the probability of some one in the immediate family needing a transplant increases with age. Even if the cord blood collection was small, and the child becomes too large to use it for a transplant, it could still be enough cells for a regenerative medicine therapy. The science of cryobiology tells us that cells which are cryogenically preserved remain viable for decades. It has been confirmed that cord blood stem cells were still viable after being frozen 23+ years.

- Who is able to donate cord blood?
In theory, any expectant mother who passes the medical screening is eligible to donate. In practice, the biggest hurdle faced by families who wish to donate is finding a bank to accept their donation. There are only about 200 hospitals in the US that collect cord blood donations from births, and most of them require you to register for donation weeks ahead of the birth. The handful of programs that accept mail-in donations are opening this opportunity to the rest of the American public.
