Cord blood contains hematopoietic stem cells used in transplants for blood cancers, marrow failure, and some inherited disorders. It can only be collected at birth. Parents should decide before delivery whether to donate to a public bank (free) or pay for private storage. Consider medical history, bank accreditation, costs, and the tradeoff with delayed cord clamping when choosing.

Why cord blood matters

Cord blood is the blood that remains in the placenta and umbilical cord after birth. It is rich in hematopoietic (blood-forming) stem cells used to treat blood cancers, bone marrow failures, certain inherited metabolic and immune disorders, and other conditions. Unlike whole bone marrow, cord blood is easier to match across donors and recipients, and cryopreserved units have been used successfully after long-term storage.

One opportunity - plan ahead

Cord blood can only be collected at birth, so expectant parents must decide and arrange collection before delivery. The collection itself is painless and quick: after the cord is clamped and cut, blood is drawn from the umbilical vein into a sterile bag. Some hospitals handle private collections and public donations directly; others require coordination with an external bank.

Public donation vs private storage

You can either donate cord blood to a public bank (no cost to you) or pay for private storage for potential family use. Public donation makes units available to patients worldwide and supports transplant programs. Private banking reserves the unit for your family but involves fees.
  • Public banks: free to donate; units are listed in registries for unrelated matches.
  • Private banks: require an enrollment process, an initial collection/processing fee, and ongoing storage fees.
Costs and fee structures vary by provider and location; compare contracts and ask about refund and release policies before signing.

Clinical uses and limits

Cord blood transplants have established roles in treating hematologic cancers, marrow failure syndromes, certain metabolic diseases, and severe immune deficiencies. Autologous use (using one's own stored cord blood) is limited for genetic disorders because the stored cells carry the same inherited mutation. Family history of a diagnosed blood or immune disorder increases the potential value of private banking.

Practical considerations

  • Timing: Arrange collection in the third trimester so hospital staff and the bank are prepared.
  • Accreditation: Choose a bank accredited by recognized bodies (for example, AABB or FACT in the U.S.).
  • Delayed cord clamping: Waiting 30-60 seconds or more benefits newborn blood volume but can reduce collected cord blood volume; discuss priorities with your provider.
  • Long-term viability: Properly cryopreserved units have been used successfully after many years in storage.

How to decide

Talk with your obstetrician, a genetic counselor if you have family medical history concerns, and the cord blood bank. Weigh the likelihood of need (family history, existing affected siblings), the benefits of public donation to the transplant community, and the costs and contract terms of private storage.

Cord blood is a potentially life-saving resource collected once, at birth. Early planning and informed choices will help you match the option to your family's medical and financial situation.

  1. Confirm recent global or national transplant counts described as 'used in transplants' and update precise figures if needed.
  2. Verify typical private bank fee ranges and current average pricing for initial processing and annual storage in 2025.
  3. Confirm guidance and research findings on effects of delayed cord clamping on collected cord blood volume and clinical recommendations.

FAQs about Cord Blood

Can cord blood be collected after delayed cord clamping?
Delayed cord clamping increases newborn blood volume but can reduce the amount of cord blood available for collection. Discuss timing and priorities with your provider and the bank before delivery.
Is private cord blood banking worth the cost?
Private banking may be worthwhile if you have a family history of blood or immune disorders or an affected sibling. For most families, public donation offers broader benefit at no cost. Compare fees, accreditation, and contract terms before deciding.
What medical conditions can cord blood treat?
Cord blood is used in transplants to treat blood cancers (like leukemia), marrow failure, certain metabolic disorders, and severe immune deficiencies. Research continues into new uses, but autologous use is limited for inherited genetic diseases.
How long can cord blood be stored?
Cryopreserved cord blood units have been used successfully after many years in storage. Proper processing and accredited storage are key to long-term viability.
How do I find a reputable cord blood bank?
Look for banks accredited by recognized organizations (such as AABB or FACT in the U.S.), transparent processing and storage protocols, clear contract and fee information, and hospital partnerships for collection.
