The only other reason to consider banking your cord blood is if you are of African, Hispanic, or Aisan descent - the reason for this is that these groups represent the smallest percentage of people who are on the National Bone Marrow Registry - it can be quite difficult to find a match for these ethnic groups. Of course, the odds that your child would ever need a bone marrow transplant or cord blood transfusion are extremely remote. If your family does not have much of a cancer risk, particularly for childhood cancers like leukemia, it is probably not worth the expense. Good luck!
