Any company not accredited within those states are not legally permitted to collect cord blood from those states, even if the company is based out of state.

Potential clients can check the current accreditation status of laboratories from the AABB list of accredited cord blood laboratories or the FACT search engine of accredited cord blood banks on their home page.

Blood banking

It is usually done within ten minutes of giving birth. Additional stem cells may be collected from the placenta. After the health care provider draws the cord blood from the placental end of the umbilical cord, the placenta is couriered to the stem cell laboratory, where it is processed for additional stem cells.

An adequate cord blood collection requires at least 75mL in order to ensure that there will be enough cells to be used for a transplantation. Before the cord blood is stored for later use, it undergoes viral testing, including tests for HIV and Hepatitis B and C, and tissue typing to determine Human Leukocyte Antigen type.

After the collection, the cord blood unit is shipped to the lab and processed, and then cryopreserved. There are many ways to process a cord blood unit, and there are differing opinions on what the best way is.

Some processing methods separate out the red blood cells and remove them, while others keep the red blood cells. However the unit is processed, a cryopreservant is added to the cord blood to allow the cells to survive the cryogenic process.

The slow freezing process is important to keep the cells alive during the freezing process. There is no consensus yet on optimal procedures for these cord blood cells, although many cryopreservation strategies suggest using dimethyl sulfoxide DMSOslow or controlled rate cooling, and rapid thawing.

Cord blood stem cells though usually from donors are currently used in the treatment of several life-threatening conditions, mainly blood and immune system related genetic diseases, cancers, and blood disorders.

The first clinically documented use of cord blood stem cells was in the successful treatment of a six-year-old boy afflicted by Fanconi anemia in Since then, cord blood has become increasingly recognized as a source of stem cells that can be used in stem cell therapy.

Cord blood stem cells can also be used for siblings and other members of your family who have a matching tissue type. Since patients who need cord blood frequently need more cells than a single collection would have provided, public banks frequently combined multiple samples together when preparing the treatment for a single patient.

Unlike bone marrow transplantation, cord blood transplantation doesn't require an exact genetic match, which makes it easier to provide patients samples form unrelated donors. Some of this is due to contamination that occasionally occurs during collection or complications arising from shipping, though this is mostly due to the fact that most cord blood collections fail to collect enough usable cells.

Because public banks do not charge storage fees, medical centers do not always have the funds required to establish and maintain them. Support for public cord-blood banking is widespread in the medical community. Forty-one cases involved blood used to treat a family member, often a sibling; in 36 of those cases the need for a transplant was known before the cord blood was collected.

Only nine cases involved giving cord blood back to the donor, a practice known as autologous transplantation and the chief selling point for private cord-blood banking. Private banks[ edit ] Private banking is typically costly to parents and not covered by insurance.

The ability to use the cord blood may also depend on the long-term commercial viability of the enterprise. Since the FDA considers cord blood stored at public banks to be "drugs", but doesn't consider cord blood stored at private banks for use by the donor to be drugs, private banks are held to a lower regulatory standard.

Minority ethnic groups have difficulty finding a perfectly matched transplant donor.

Studies have found that allogeneic transplants have a better outcome when the donor and patient are related. The policy of the Society of Obstetricians and Gynaecologists of Canada SOGC supports public cord blood banking similar to the collection and banking of other blood products, i.

The policy of the American Academy of Pediatrics states that "private storage of cord blood as 'biological insurance' is unwise" unless there is a family member with a current or potential need to undergo a stem cell transplantation.

Private storage of one's own cord blood is unlawful in Italy and France, and it is also discouraged in some other European countries.

Ownership of cord blood[ edit ] As ofcontracts of the largest cord blood banks do not explicitly state that the cord blood belongs to the donors and child with all the rights and privileges one would reasonably expect from ownership. The ambiguity leaves open future uses not approved by the donors and child.

The majority of private cord blood banking facilities, the mother owns all rights to the cord blood that was banked, until the minor in which the cord blood was taken turns eighteen. At that time the minor has all rights to his or her own banked cord blood.

Concerns have been raised that the current interest in cord blood could cause a perception that cord blood is "unused" by the birth process, thus decreasing the amount of blood which is infused into the child as part of the birth process.

With the demand for cord blood increasing, there is a possibility that the cord could be clamped prematurely to preserve even more "extra" cord blood.

Both private and public cord blood banks have developed in response to the potential for cord blood in treating diseases of the blood and immune blood [blud] the fluid that circulates through the heart, arteries, capillaries, and veins and is the chief means of transport within the body.

It transports oxygen from the lungs to the body tissues, and carbon dioxide from the tissues to the lungs.

It transports nutritive substances and metabolites to the tissues and removes waste products to the Medical Definition of Blood bank Blood bank:: A place where blood is collected from donors, typed, separated into components, stored, and prepared for transfusion to recipients.

A blood bank may be a separate free-standing facility or part of a larger laboratory in a hospital.
