Florida 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. Florida was the second state to explicitly endorse the use of educational materials from Parent's Guide to Cord Blood Foundation. The Florida bill was enacted 17 June 2011 and became effective 1 July 2011.
- Recommendations from Parent's Guide to Cord Blood
- Educate expectant parents about all their options for cord blood (Education)
- Choose a family bank that meets all your national and local regulations, plus has been inspected by an accreditation agency (Lab Standards)
- Choose a family bank that uses a specialized courier to transport cord blood (Find a Family Bank), or in some countries the family can hire a specialized courier directly (Shipping & Handling).
- 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.
- Why is it important to ship cord blood with a special courier?
The Parent's Guide to Cord Blood Foundation recommends shipping with a courier that has a division specializing in "Life Sciences" transport. This helps to insure that your critical shipment is not misplaced, arrives promptly, and is maintained within the acceptable temperature range during transport from the hospital to the lab.
The first priority for parents to consider is the cord blood shipping time: Once the cord blood is harvested, the blood cells and stem cells gradually begin to die. Public cord blood banks set a limit of 48 hours on the time between birth and processing the blood for cryogenic storage. It would be a "best practice" if family banks also followed the 48 hour window.
The second priority for parents to consider is the cord blood shipping temperature: The standard procedure for transporting fresh cord blood is to keep it within an ambient temperature range of 15 °C (59 °F) to 25 °C (77 °F). Priority shipping services may guarantee the arrival time, but not the temperature conditions during transit. The cord blood might get too hot or too cold while sitting in the back of a truck, on a loading dock, or in the cargo hold of an airplane. A specialty courier with Life Sciences expertise will carry the cord blood in a controlled environment.
Parents can improve the survival of their child's cells during transit to the cord blood laboratory by selecting a family bank that provides a well insulated shipping container and that provides a specialty courier who maintains the shipment within the desired temperature range. In many countries it is standard practice for the shipping container to have a temperature logger.
In the United States, the post 9/11 security requirements of the Transportation Security Administration (TSA) require that specialty couriers can only offer cord blood shipping through those cord blood banks that are registered with the TSA as a "Known Shipper". Before 9/11, specialty couriers could market their services directly to consumers, and in some countries this is still possible. Parents should check if a Family Bank offers specialty courier services before they sign a contract.
