Oklahoma 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 Oklahoma bill was enacted 15 May 2008 and became effective 1 July 2008.
- What is the role of the Parent's Guide to Cord Blood Advisory Panel?
- Our panel of scientific and medical experts reviews and approves our educational brochures. Each member may assist with development of new web content in his or her area of expertise. The panel is also on-call to answer difficult questions from readers.
- Will my delivery hospital allow me to use any family bank?
In the US, the answer to this question is almost always YES. However... a handful of hospitals have signed exclusive contracts requiring their patients to use certain family banks, so it is best to check in advance.
Those hospitals who have made exclusive partnerships will argue that it improves their level of care, because their staff train with and stock the collection kits for the banks they have approved. The hospital probably has a financial incentive too. However, for parents it means a lack of consumer choice.
- Processing: Must cord blood be processed before storage?
The earliest cord blood transplants were performed with whole cord blood. Thus, it is not absolutely necessary to process cord blood in order to save patient lives. There has never been a prospective randomized trial to compare transplant patient outcomes with cord blood that had been stored whole versus processed.
Most cord blood banks, both public and private, now process cord blood to remove both the plasma and the red cells, and cryo-preserve the remaining buffy coat holding stem cells. Some banks also save the removed red cells and plasma in companion storage. Some banks save a sample of maternal blood.
The removal of plasma is also called volume reduction. The volume reduction enables more collection units to fit in a freezer and requires less cryogenic nitrogen per unit.
Also, the majority of banks remove red blood cells prior to freezing, primarily because these cells often burst during freezing and release iron from hemoglobin that can be toxic. The alternate to removing the red cells before freezing is to wash any broken cells out of the collection upon thaw. Removing the red cells also removes the donor's blood type (the ABO and Rh types). When cord blood goes from a donor to a patient for a transplant, the donor and patient can be compatible on all the HLA types used for transplant matching and still have incompatible red blood types.
