Cord Blood
How Is Umbilical Cord Blood Collected? Immediately after delivery of the baby, the umbilical cord is clamped and the baby is separated from the cord. At this point, the needle attached to the collection bag is inserted into one of the three veins in the umbilical cord. By gravity taking its course, the umbilical cord blood then flows into the collection bag. The bag comes equipped with an anti-coagulant to keep the blood from clotting before it reaches a laboratory. The process is non-invasive, painless, and unlike traditional bone marrow collection which usually requires a general anaesthesia and recovery, generally takes between three and five minutes to complete. The Blood Cord Bank supplies patients with a cord blood collection kit prior to delivery date to bring along with them to the hospital for the physician or midwife to collect the cord blood after delivery. What Happens Once the Blood Is Drawn? Once the attending physician or midwife has completed the umbilical blood collection, the sample is either picked up by a local courier or by a Overnite Express Shipper to be sent to a Blood Cord Laboratory. If your blood is coming from a destination outside the Blood Cord Bank's local area, you can use a Worldwide Shipper that ships via priority overnight to ensure that your blood arrives within 72hrs of delivery. Once the blood arrives at a Blood Cord laboratory, it is assigned to a technician who will see the processing and cryopreserving through to fruition. Most Blood Cord Banks have entrusted a Worldwide Shipper with their business, and shipping of your baby's precious cord blood. Most will use the #1 shipper in the world of diagnostic specimens. How Are the Cells Stored? Each cord blood that arrives at a Blood Cord laboratory is given a unique identifying number. Once the stem cells are separated from the blood they are placed in 5 ml cryo-vials in preparation for freezing and storage. Each vial is clearly marked with: Cord Blood Number, Date of Birth, Baby's Name, Date of Processing, and Contents, before it is sent to the first stage of the cryopreserving process. The vials are placed into two different temperature cryo-tanks before being submerged into a liquid nitrogen tank. This process is to ensure the safety of the cells. The progression to lower and lower temperatures keeps the cells from going into shock from the extreme negative temperature of -321° Fahrenheit. All of tanks are usually located in a highly monitored and secured facility. What Solvent Is Used to Prevent the Cells from Freezing? Blood Cord Banks use a cryo-protectant, DMSO (Dimethyl Sulfoxide) to act as a shield around the stem cells. This solution is spun out of the stem cells in the removal and usage by for a transplant. Where Is the Storage Facility Actually Located? All processing and storage is done at a state-of-the-art facility, centrally located near medically facilities. A good Blood Cord Bank should not and do not send your baby's cord blood out to any third party for processing or storage. This not only allows your Blood Cord Bank to monitor your stem cells in their laboratory and highly secured storage facility, but also permits them to mediate their spending; making Blood Cord Storage more affordable.
