Blood Cord Banking Pros And Cons

Cord blood banking has become an increasingly popular option for parents looking to secure a potentially life-saving resource for their children and family members. Cord blood, which is the blood collected from a newborn’s umbilical cord immediately after birth, is rich in hematopoietic stem cells. These cells can develop into various types of blood cells and have been used in the treatment of numerous medical conditions, including certain cancers, blood disorders, and immune deficiencies. However, despite its potential benefits, cord blood banking also involves significant costs and considerations. This article will explore the pros and cons of cord blood banking in detail to help you make an informed decision.

Introduction to Cord Blood Banking

Cord blood banking involves the collection and storage of a newborn’s umbilical cord blood for potential future medical use. This process can be done through either private or public cord blood banks. Private cord blood banks store the blood exclusively for use by the donor child or family members, while public banks store donated cord blood for use by anyone who needs it.

The potential medical applications of cord blood stem cells are vast and continue to expand as research progresses. These stem cells have the ability to regenerate and repair damaged tissues, making them valuable in treating a variety of diseases. However, the decision to bank cord blood should be made after considering both the potential benefits and the associated costs and limitations.

Pros of Cord Blood Banking

Potential Life-Saving Treatments

One of the most compelling reasons to bank cord blood is its potential to save lives. Cord blood stem cells can be used to treat more than 80 different diseases, including leukemia, lymphoma, anemia, and various genetic and metabolic disorders. In many cases, a cord blood transplant can be a more effective treatment option than bone marrow transplants.

Ease of Collection

The process of collecting cord blood is simple, safe, and painless for both the mother and the baby. It is performed immediately after birth, whether it is a vaginal delivery or a cesarean section, and does not interfere with the birthing process. This makes it an accessible option for most families.

Matching and Compatibility

Cord blood stem cells are more adaptable and less likely to cause rejection than bone marrow stem cells. They do not need to be an exact match, which increases the likelihood of successful transplants. This is particularly important for families with a history of genetic disorders or when there is a need for a stem cell transplant.

Potential Future Uses

The field of regenerative medicine is rapidly advancing, and new treatments and therapies using stem cells are being developed. Banking cord blood now may provide access to these future medical advancements. This includes potential treatments for conditions like diabetes, cerebral palsy, and spinal cord injuries.

Increased Availability for Minorities

Minority populations often face difficulties in finding compatible bone marrow donors due to a smaller donor pool. Banking cord blood can provide a source of stem cells that are more likely to be compatible with the donor child or family members, increasing treatment options for minorities.

Autologous Transplants

Cord blood stored in private banks can be used for autologous transplants, where the stem cells are used by the donor child. This eliminates the risk of graft-versus-host disease, a common complication in allogeneic transplants (using donor cells).

Ethical and Non-Controversial

Unlike some stem cell sources, cord blood collection is free of ethical controversies. It involves collecting blood from the umbilical cord, which is usually discarded after birth. Therefore, there are no ethical concerns related to the destruction of embryos or other contentious practices.

Speed of Availability

Cord blood is cryogenically frozen and can be readily available for use when needed. In contrast, finding a suitable bone marrow donor can be a lengthy process, involving donor searches and compatibility testing, which can delay treatment.

Potential for Family Use

Cord blood stored in private banks can be used by family members, including siblings, who may need a stem cell transplant. This can be particularly valuable for families with a history of genetic disorders or diseases that are treatable with stem cells.

Advances in Research

Ongoing research continues to explore new uses for cord blood stem cells, potentially expanding the range of treatable conditions. By banking cord blood, you may be contributing to the advancement of medical science and future treatments.

Cons of Cord Blood Banking

High Costs

One of the primary drawbacks of private cord blood banking is the cost. Initial collection and processing fees can range from $1,000 to $2,500, with annual storage fees averaging between $100 and $300. These costs can add up significantly over time, making it a financial burden for some families.

Limited Immediate Use

While cord blood has potential for future medical use, the likelihood of needing it for treatment in the near term is relatively low. Current estimates suggest that the chances of a child using their own stored cord blood range from 1 in 400 to 1 in 200,000, depending on the source of the statistics.

Public Banking Alternatives

Donating cord blood to a public bank is free and can benefit a wider population. Public banks do not charge collection or storage fees, and the donated cord blood is made available to anyone in need. This altruistic option can save lives without the financial burden associated with private banking.

Limited Cell Quantity

The amount of stem cells in a single cord blood collection is limited, which may not be sufficient for treating an adult patient. In some cases, multiple cord blood units may be required for a successful transplant, which can complicate treatment plans.

Storage and Viability Concerns

While cord blood can be stored for many years, there are concerns about the long-term viability of the stem cells. Research is ongoing to determine the optimal storage duration, but there is currently no consensus on how long cord blood remains effective.

Regulatory and Quality Variations

The quality and regulatory standards of cord blood banks can vary widely. Not all banks are accredited by organizations like the American Association of Blood Banks (AABB) or the FDA. Choosing a reputable and accredited bank is crucial to ensure the quality and safety of the stored cord blood.

Ethical Considerations for Private Banking

While cord blood collection itself is ethically non-controversial, the practice of private banking raises questions about equitable access to medical resources. The high cost of private banking may limit access to those who can afford it, potentially exacerbating health disparities.

Uncertain Future Applications

While the potential future applications of cord blood stem cells are promising, many treatments are still in experimental stages. Investing in cord blood banking based on speculative future uses may not be justifiable for all families.

Alternative Stem Cell Sources

Bone marrow and peripheral blood stem cells are viable alternatives to cord blood stem cells and have been used successfully in many treatments. These alternatives are often more readily available and may not require the same financial investment as cord blood banking.

Lack of Guarantees

There are no guarantees that the stored cord blood will be usable when needed. Factors such as contamination during collection, storage failure, or the development of the same genetic condition in the cord blood can render the stored cells unusable.

Potential for Conflict of Interest

Some medical professionals and institutions may have financial ties to private cord blood banks, potentially influencing their recommendations. It’s essential to seek unbiased information and consider multiple sources before making a decision.

Misleading Marketing Practices

Some private cord blood banks may use aggressive marketing tactics to promote their services, sometimes overstating the likelihood or benefits of using stored cord blood. Parents should be cautious and seek out accurate, evidence-based information.

Emotional Decision-Making

The decision to bank cord blood can be emotionally charged, especially for expectant parents wanting to do everything possible to protect their child’s future health. It’s important to balance emotional impulses with rational consideration of the facts and financial implications.

Storage Facility Risks

Natural disasters, power failures, or other unforeseen events could potentially compromise the storage facility and the viability of the stored cord blood. While banks typically have safeguards in place, the risk cannot be entirely eliminated.

Potential Redundancy with Sibling Donations

If you have already stored cord blood for one child, the likelihood of needing additional cord blood for a sibling may be reduced. The genetic similarity between siblings means that previously stored cord blood may already cover potential future needs.


Cord blood banking offers both significant benefits and notable drawbacks. The potential to save lives and the promise of future medical treatments make it an appealing option for many families. However, the high costs, limited immediate use, and ethical considerations require careful deliberation. Public cord blood banking provides a cost-free alternative that can benefit a broader population, while private banking offers the security of having a readily available, genetically compatible resource.

Ultimately, the decision to bank cord blood should be based on a thorough evaluation of your family’s medical history, financial situation, and personal values. Consulting with healthcare professionals and seeking information from reputable sources can help you make an informed choice that aligns with your long-term health and financial goals. By understanding the full implications of cord blood banking, you can take a proactive step toward safeguarding your family’s future health.
