Arizona has state legislation around cord blood education that follows the Institute of Medicine guidelines and mandates/encourages physicians to educate expectant parents about ALL forms of cord blood banking. The Arizona bill was enacted 26 Jan. 2006 and became 1 Jan. 2007.
- 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.
- What is delayed cord clamping?
Some people feel that the blood in the umbilical cord should be allowed to flow into the baby and that the cord should not be clamped while it is still pulsing. Medical studies have shown that, particularly in parts of the world with poor infant health care, delayed cord clamping can help protect the baby from anemia (low blood counts) during the first 6 months of life. However, a prolonged delay will allow the blood in the cord to clot, and the opportunity to collect the blood for stem cells will be lost. Therefore, if clamping is delayed, it should not be more than two minutes.
