Wisconsin has state legislation around cord blood education that only mandates/encourages physicians to educate expectant parents about public donation of cord blood. The Wisconsin bill was enacted 15 Dec. 2005 and became effective 30 Dec. 2005.
- What questions should parents ask a Family Bank about Company Stability?
- Is the family cord blood bank a publicly-held or privately-held company?
- Is the company affiliated with a hospital or research institution?
- Is the company involved in bio-technology research and development?
- What other medical services does the company perform?
- How long has the company been banking cord blood?
- Who directs the day-to-day business of the company? Many cord blood banks have famous doctors on their Board of Directors; but they are not involved with the day-to-day operations.
- What is the lab inventory of cord blood collections, both public and private? This speaks to their staff's experience with storing cord blood.
- How many cord blood collections has the bank released from their own lab for therapy? This speaks to their staff's experience with releasing cord blood.
- What are the most important things to do when collecting cord blood?
1. Read the instructions on the kit! Too many healthcare providers think that they don't need to read and follow instructions.
2. Sterilize before every needle stick. When in doubt, sterilize again!
3. Volume, volume, volume. You want to "milk the cord" for as much blood as possible. If the blood vessel you are using stops working, try another or move upstream, but sterilize first.
- How much blood and stem cells does a typical umbilical cord hold?
The median size of cord blood collections in family banks is 60mL or 2 ounces. That small volume of liquid corresponds to 470 million Total Nucleated Cells (TNC) or 1.8 million cells that test positive for the stem cell marker CD34. Thus, most healthy full-term babies have over a million blood-forming stem cells in their umbilical cord blood. By comparison, most public cord blood banks will only keep collections that are much bigger than average, and throw out the donations that are below a threshold of a billion TNC, corresponding to a blood volume of about 90-100 mL or 3 ounces.
