Ohio 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 Ohio Dept. of Health has officially adopted the educational materials from Parent's Guide to Cord Blood Foundation. The Ohio bill was enacted 31 Mar. 2010 and became effective 1 July 2010.
- 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.

- 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.
- What questions should parents ask a Family Bank about Company Stability?
- Is the family cord blood bank a publicly-held or privately-held company?
- Is the company affiliated with a hospital or research institution?
- Is the company involved in bio-technology research and development?
- What other medical services does the company perform?
- How long has the company been banking cord blood?
- Who directs the day-to-day business of the company? Many cord blood banks have famous doctors on their Board of Directors; but they are not involved with the day-to-day operations.
- What is the lab inventory of cord blood collections, both public and private? This speaks to their staff's experience with storing cord blood.
- How many cord blood collections has the bank released from their own lab for therapy? This speaks to their staff's experience with releasing cord blood.
