Wisconsin has state legislation around cord blood education that only mandates/encourages physicians to educate expectant parents about public donation of cord blood. The Wisconsin bill was enacted 15 Dec. 2005 and became effective 30 Dec. 2005.
- Are related donors better for transplants?
The overall answer is yes, but this is a complex topic.
The two important measures of patient outcome are: long-term survival, and the impact on quality of life from graft-versus-host disease (GvHD). Sibling donors tend to trigger less GvHD. Also, sibling donors are available faster than searching for an unrelated donor, and patients have better survival when they go to transplant faster after diagnosis.
The exact comparison of outcome between sibling or unrelated donor varies with the patient diagnosis. The NMDP website has a page on this, with numerous references. For many cancers the outcomes are comparable, although sibling donors have a slight edge. The largest study was by Weisdorf et al. 2002, for over 2900 patients with CML leukemia. When correcting for all other factors, the survival with sibling donor vs unrelated donor was 68% vs. 61%. Sibling donors show a significant improvement for pediatric cord blood transplants of hereditary disorders. The European Blood and Marrow Transplantation Group (EBMT) reported 3 year survival rates of 95% from a sibling donor vs. 61% from an unrelated donor.

- Why is it important to choose a Family Bank that is accredited?
The Parent's Guide to Cord Blood Foundation recommends that parents select a Family Bank whose laboratory has been inspected and accredited by an accreditation agency specific to cord blood banking, as this provides a degree of quality assurance.
In some countries, national regulations hold Family Banks to the same standards as Public Banks, so an independent accreditation is not necessary (Examples: Germany, Israel). But in most countries the federal requirements for Family Banks are not as strict as Public Banks, and then a voluntary accreditation is desirable. For example, in the United States the FDA registers and inspects Family banks, but does not require them to have a BLA License like Public Banks.
Caveat: The process of registering with an accreditation agency and getting inspected can take a year, so it is understandable if a brand new lab does not have an accreditation yet.
- What questions should parents ask a Family Bank about collecting cord blood?
- What instructional tools are provided for the physician and delivery staff?
- Will the cord blood company actively contact the labor and delivery staff for you -- or are parents responsible for keeping them informed and coordinated?
- What collection method do they use: gravity drip or blood draw?
- Is the collection blood bag sterile, both inside and out, so that it can be used in the operating room for a C-section?
- Do they provide the option of collecting additional stem cells from the placenta or tissue of the umbilical cord?
