Parents will often ask what is our method of cord blood collection. We used a closed system because we believe it is the best way to prevent contamination. The blood is collected in a bag and transferred through a tube into another bag for processing. This prevents the cord blood from ever touching the air so it cannot be contaminated. Although some laboratories still use the syringe method of collection, the closed method is becoming the industry standard and will soon be required of all labs.
Your health care provider should try to collect as much blood as possible. This way, you have a better chance of getting a higher CD 34+ count. When the blood is finally moved into bags for storage, a number of separate vials are kept so that if the blood is ever considered of transplantation, it can be checked and tested without thawing the entire sample.
