HLA matching is used to ensure that there is a match between a donor and recipient to prevent the chance of rejection of the donated cells. If you choose to bank your child’s cord blood, you will eliminate the possibility that the donated stem cells are not HLA matched to your child. Stem cells from your child will always be a perfect match to you child. By banking your child’s cord blood, your child’s own stem cells will be ready for use at all times during the lifetime of your child.
