Cord blood bank is where you can preserve the cord blood to use in future. There are two types of cord blood bank that is private cord bank and public banks. The cord blood which is stored in the bank is used to treat diseases related to blood and immune disorders.
Public banks accept the donations and use the donated blood cord to the person who are in need of it. Public cord blood banks are supported largely by the medical centers. There are many strict regulations that should be followed by the public cord blood banks in order to allow the donated unit of blood to enter the registry of the bank. An expectant mother can donate the blood if she is interested. She can contact the cord blood bank before thirty four weeks of pregnancy. You can find various lists of public cord blood banks in the websites of the National Marrow Donor Program. Once the blood is donated to the blood bank, it will lose all its recognizing information after initial testing process. Even the families will not be able to recover their own blood once it is donated. So it is impossible to use the sample for themselves.
But the Private Banks store the cord blood and it is linked with the donor, so that the relations can recover the blood cord if needed in the near future. The parents can also have charge of the cord blood in the bank for a long time so as until their child turns to an adult. The private banks preserve the cord blood so that it might be used in one or the other day. It may be required either for the donor’s baby or by a relative who is a biologically related to the donor. Private cords bank charge bulky fee to preserve the cord blood of the donor through the family’s biological insurance.
Collection process of the cord blood
The Cord blood is collected after the cord is cut and removed from end of the cord collecting up to 75 +/- 23 ML of  blood. The blood is usually collected within ten minutes of the birth of the baby. They also collect a few extra stem cells from the placenta and it is stored in Placenta Cord Bank.
Before storing the blood for future use, the blood is tested for viruses which  includes tests like HIV, Hepatitis B and Hepatitis C and they also determine the HLA type of the tissue.
By using own cord blood cells, it would be more effective especially for childhood leukemia cancers. Children who have immunological disorders who are usually unable to utilize their own cord blood for future use as the stored blood will also contain the some genetic defect. According to the research most of the transplanted blood cord are stored in the private cord blood bank and is being used by the relatives of the donor and not by the donor.
