- Processing: How is cord blood processed before storage?
The three main components of cord blood, like any blood collection, can be separated by weight: the heaviest layer is the red blood cells (RBC), the lightest is the plasma (a clear white liquid), and in the middle is a pinkish layer called the "buffy coat" which contains the white blood cells (WBC), including stem cells. When banks process the cord blood, the final separated component that goes into storage is the buffy coat, even though only about 1% of the cells are actually stem cells. There is no procedure to separate out the stem cells alone.
The vast majority of blood processing methods rely on the different density of the three main blood components. They can be separated by sedimentation, or by centrifuge, or by a combination of the two techniques. The procedure can be performed manually by trained technicians or by automated machine.
- 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.
- 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.
