North Carolina 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 North Carolina bill was enacted 8 June 2009 and became effective 8 June 2009.
- What questions should parents ask a Family Bank about Laboratory Standards?
- Is the cord blood laboratory accredited by an agency that has specific standards for cord blood banks and conducts inspections? (ex: AABB, FACT, ISO)
- Some US states license cord blood banks (CA, MD, NJ, NY): Do they operate in those states? Note that the California Biologics License is based on AABB accreditation, but lags behind the latest AABB updates.
- Does the lab process cord blood around the clock, or only on selected shifts?
- What tests does the lab perform on maternal blood?
- What tests does the lab perform for infectious disease markers?
- What tests does the lab perform for contamination?
- Does the lab ever reject cord blood collections on the basis of the tests of maternal blood, infectious diseases, or contamination?
- Does the lab maintain a "quarantine tank" for the storage of blood that might be able to transmit an infection?
- What tests does the lab perform to measure the stem cell count of the processed cord blood and the stem cell viability?
- Does the lab/bank inform parents, prior to storage, if the collection is too small for a transplant, and give them the option not to save it?
- Does the lab/bank offer parents a refund if the cord blood collection has certain problems (contamination, low volume)? These refunds are typically only offered if the bank performed the collection as part of their service.
- What information will parents receive in the final report about their stored cord blood?
- How is cord blood collected?
It literally only takes minutes to save the stem cells in cord blood. Once the cord is clamped, the cord is wiped with antiseptic and a needle is inserted into one of the veins in the umbilical cord to withdraw a few ounces of blood.
There are two methods of collection in common use. One is to hang a blood bag lower than the mother and let gravity draw blood down the tube into the bag. This method is used in most countries of the world, because it has the fewest steps, and therefore the fewest opportunities for mistakes or contamination.
The second method is to actively draw the blood out, just like when a person has a blood draw for a medical test. The draw can be done with a standard syringe or with a bulb in the bag tubing that creates suction. Studies have shown that actively drawing the blood will collect a larger volume faster.
- What are the most important considerations in picking a family bank?
1. Nationality - You must follow the national regulations of the country where you will give birth.
2. Travel conditions - It is best to pick a bank that can receive and process the cord blood within 48 hours of birth. It is also best for the cord blood to be shipped in a transport container that will maintain it at close to "room temperature".
