1. How much cord blood should be collected?
As much as possible! This is because the higher the volume, potentially more stem cells can be harvested and in turn, enhance the success rate of transplant. The average volume collected ranges from 30ml to 150ml. There is a minimum volume of 30ml before our laboratory will proceed with processing the cord blood unit collected.
2. How is cord blood collected?
When parents choose to store their baby’s cord blood with CRYOLIFE, a collection kit will be given to the family. This kit contains items necessary for cord blood collection, and is taken by the family to the hospital at the time of delivery. The collection process is similar to drawing blood for a blood test. After the baby has been delivered and the umbilical cord has been clamped, your doctor will collect the cord blood trapped in the umbilical vein and placenta using the sterilized blood collection kit we provided. Collection can take place when the placenta is still in the uterus or after it has been delivered. If the cord blood is collected after the placenta is delivered, it should be carried out within no more than 10 minutes before the cord blood starts to clot.
4. What procedures shall be observed once the cord blood is drawn?
Once the family receives the kit with the collected cord blood, they shall call our hotline, 2110-2121, to notify us for pickup. The cord blood must remain in room temperature after the collection.
5. How long can the cells be stored?
Theoretically, cord blood can be stored for a long period of time once it is cryogenically frozen. Research found that the viability and performance of umbilical stem cells was not compromised after the cord blood have been stored for fifteen years.
6. What should we do if we forgot to bring along the cord blood collection box (Baby Box) to hospital?
Don’t worry! We have stored some emergency box in hospitals. If you forgot to bring the collection box, you can ask for assistance from nurse or midwives. Inform them you have registered for the service from CRYOLIFE and they will arrange another collection box for you.
Once the cord blood is drawn, please call our customer service hotline and inform us you have changed to use a emergency box. Our staff will arrange all the follow-up procedures and no additional fee will be charged.
7. Why the service plan set up-to 18-year? Can we store the cord blood sample more than 18 years?
Theoretically, cord blood can be stored for a long period of time once it is cryogenically frozen. 18-year plan is based on the requirement of Hong Kong Ordinances. As the infant donor has the full right of the ownership to the stored cord blood stem cells, he or she needs to sign a new service agreement with CRYOLIFE at the age of majority. So, service agreement signed with the parents is then set as 18-year.
