New Mexico has state legislation around cord blood education that only mandates/encourages physicians to educate expectant parents about public donation of cord blood. The New Mexico bill was enacted 19 Mar. 2005 and became effective 1 Jan. 2006.
- How is the website of the Parent's Guide to Cord Blood unique?
- Only searchable map of US donation locations.
- Only worldwide directory of private/family cord blood banks that is actively maintained.
- Only website offering a Compare Banks tool that is not a marketing feature of one of the Banks.
- Only list of "diseases treated" that differentiates between standard vs. experimental therapy, and whether the treatment uses stem cells from the patient vs. a donor.
- Only cord blood web site that is accredited by Health on the Net (HON) standards for accuracy and ethics.
- How much cord blood is needed for a transplant?
The crucial thing is not the volume of the cord blood collection, but the number of stem cells it contains. Transplant doctors develop recommendations based on the Total Nucleated Cell count, or TNC, because it is the easiest measure to reproduce between different labs. For treating cancer, the transplant dose should be at least 25 million TNC per kilogram of patient body weight (1 kilogram equals 2.2 pounds). The average cord blood collection holds 8.6 million TNC per mL. Thus, the optimal transplant dose requires harvesting:
1.3 mL of cord blood for every pound of patient weight, -or-
2.9 mL of cord blood for every kg of patient weight
However, as more transplant centers are adopting the practice of giving adult patients "double cord blood transplants" with two cord blood units, it is less critical for both units to have adequate cell dose.

- 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.
