Public vs Private Cord Blood Banking: What Doctors Recommend

Curated by Michel Oliver, Restore Wellness Group · Independent Health Researcher & Patient Advocate · Last reviewed October 2026 · How we research

About this guide: We are independent patient researchers, not medical doctors. We review peer-reviewed literature (PubMed), government trial registries and regulators’ guidance, plus documented patient reports, to help you navigate clinic options and spot predatory marketing. How we research.

IN SHORT

Public cord blood banks store donated units free of charge for any patient who matches, while private banks store your baby’s cord blood for your family for a fee. The American Academy of Pediatrics and ACOG both recommend public donation and do not support routine private banking.

What is public vs private cord blood banking?

Both kinds of bank collect and freeze the blood-forming stem cells left in the umbilical cord after birth. A public bank lists units on national registries for transplant patients, much like blood donation. A private bank keeps the unit reserved for your child or relatives. Directed family banking, when a relative already needs a transplant, is a recognised exception.

How it works

For public donation, you consent at a participating hospital, the unit is collected after birth, and it is tested; units too small or failing tests may be used for research or discarded. For private banking, you contract with a company, which sends a kit, collects via hospital staff, and stores the unit for an annual fee. Public units must meet strict cell-count and quality standards before listing. Private units are stored whatever their size.

Legal status

In the US, public banks that supply unrelated patients need an FDA licence (or must operate under an investigational application), while private banks register with the FDA and follow tissue rules but need no approval for family storage. The AAP’s 2017 policy statement recommends public banking and supports private banking only when a family member has a condition treatable by stem cell transplant.

ACOG’s 2019 Committee Opinion 771 states routine private banking is not supported by evidence and public banking is recommended. Several European countries regulate private banking tightly, and public banks there are often run by health systems.

What the evidence shows

Cord blood transplants are an accepted treatment for over 80 disorders, mainly blood cancers and inherited blood and immune conditions. The AAP notes public cord blood is used about 30 times more often than privately stored units. ACOG estimates the lifetime chance of needing one’s own cord blood at about 1 in 400 to 1 in 2,500. A child’s own cord blood usually cannot treat their own genetic disease or leukaemia. Public donation also helps patients from under-represented ethnic groups, who have a harder time finding matched donors.

Commonly marketed for

Private: ‘biological insurance’ for the child
Private: potential use for siblings or parents
Private: future regenerative medicine
Public: transplants for unrelated patients with leukaemia and lymphoma
Public: sickle cell disease and inherited immune disorders
Both: research when units are not suitable for transplant

Cost

Typical price range: $0 – $5,745. Public donation is free. Private banking costs about $710 to $2,350 upfront plus $100 to $199 a year, or up to about $5,745 prepaid for lifetime storage (GoodRx; AAP HealthyChildren.org).

Risks

Private: high cost for a very low chance of use
Private: a child’s own cells usually cannot treat their genetic disease
Public: you have no claim to the unit later, although a public unit may still be found if needed
Collection may be limited by delayed cord clamping or birth complications
Not all hospitals take part in public donation

Questions to ask first

Does my delivery hospital take part in public cord blood donation, and how do I sign up?
Does anyone in our family have a condition treatable by stem cell transplant, making directed banking reasonable?
Is the private bank accredited, and what are the total long-term fees?
Will collection change our plan for delayed cord clamping?

Public vs Private Cord Blood Banking: FAQs

What do pediatricians recommend?

The American Academy of Pediatrics recommends public donation. It supports private banking mainly when a family member has a condition treatable with a stem cell transplant.

What do obstetricians recommend?

ACOG’s 2019 opinion says public banking is recommended and routine private banking is not supported by the evidence.

If I donate publicly, can I get it back?

You give up rights to the unit, and it may be used by another patient. If your family later needs a transplant, registries can search all public units for a match.

Can a child use their own cord blood?

Rarely. For genetic diseases and many leukaemias, the child’s own cord blood carries the same problem, so donor cells are usually needed.

What happens to public units that are too small?

They may be used for research or quality testing, or discarded. Only units with enough cells are listed for transplant.
