Louisiana 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 Louisiana bill was enacted 12 June 2008 and became effective 15 Aug. 2008.
- 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: 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.
- 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.
