Saving your baby’s umbilical cord means collecting the blood and tissue from the cord immediately after birth and storing it in a specialized bank for potential medical use. The process is painless for both you and your baby, but it requires planning well before your due date. You’ll need to choose between public donation (free, but you give up ownership) and private storage (costs roughly $1,500 to $2,800 upfront, plus annual fees).
What You’re Actually Saving
The umbilical cord contains two distinct sources of stem cells, and they serve different purposes. Cord blood is rich in stem cells that form the blood and immune system. These are the only cord-derived cells currently approved by the FDA for medical treatment, used in transplants for certain blood cancers, inherited metabolic disorders, and immune system conditions. Cord blood transplants have been performed in humans for over 25 years.
Cord tissue, the physical structure of the cord itself, contains a different type of stem cell that can develop into bone, cartilage, skin, nerve tissue, and circulatory tissue. These cells are still being studied in clinical trials for conditions like heart disease, ALS, multiple sclerosis, Alzheimer’s, and sports injuries. No FDA-approved treatments use cord tissue yet, but many families choose to bank it alongside cord blood as a hedge on future medicine.
Public Donation vs. Private Storage
Public cord blood banks accept donations at no cost to your family. The donated cord blood becomes available to any patient who needs a transplant, similar to donating blood. You give up ownership, meaning your family can’t reclaim it later. Not every hospital participates in public cord blood collection, so you’ll need to confirm your delivery hospital is a collection site.
Private (family) cord blood banks store the sample exclusively for your family’s use. These banks are available nationwide, but they come with significant costs. At one major private bank, processing and courier fees range from about $1,486 for cord blood alone to $2,792 for a premium cord blood and cord tissue package. Annual storage fees run $199 for cord blood or $398 for cord blood and tissue combined, billed every year on your child’s birthday. Over 18 years, the total cost can exceed $5,000 to $10,000 depending on the plan.
The practical tradeoff: public donation is free and helps others but removes your access. Private banking preserves your family’s options but represents a long-term financial commitment for something you may never use.
How Collection Works
Collection happens in the minutes after delivery, and it doesn’t interfere with your birth experience. After your baby is born and the umbilical cord is clamped and cut, a second clamp is placed about 8 to 10 inches from the first. A healthcare provider then draws blood from the clamped section of cord into a collection bag or specimen tube. The entire process typically takes under 10 minutes and is completely painless for both mother and baby.
If you’re also banking cord tissue, a segment of the cord itself is cut and placed in a separate container. Both samples are then shipped in the provided collection kit to the bank’s processing facility, where they’re tested, processed, and frozen in liquid nitrogen for long-term storage.
Delayed Cord Clamping Compatibility
Many parents want both delayed cord clamping and cord blood banking, and they’re not fully incompatible, but there is a tradeoff. The American College of Obstetricians and Gynecologists recommends delaying cord clamping for at least 30 to 60 seconds after birth. During this window, about 80 milliliters of blood transfers from the placenta to your baby in the first minute, reaching roughly 100 milliliters by three minutes.
That transfer reduces the volume of blood left in the cord for collection. A shorter delay (30 to 60 seconds) still allows a reasonable collection volume in most cases, while a longer delay (2 to 5 minutes, as some midwife organizations recommend) may leave too little blood for a viable banking sample. Discuss your priorities with your provider beforehand so the delivery team knows the plan. Delayed clamping carries no increased risk of postpartum hemorrhage or excess blood loss for the mother.
Timeline for Getting Started
Don’t wait until the third trimester to begin researching. The Cleveland Clinic recommends making your decision by about 34 weeks of pregnancy. If you choose private banking, you’ll need time to enroll with a bank, complete a health history questionnaire, sign consent forms, pay the initial collection fee, and receive your collection kit. Many hospitals don’t keep cord blood collection kits on hand, so one must be shipped to your delivery location ahead of time.
A practical schedule looks something like this:
- Weeks 20 to 28: Research banks, compare pricing and reviews, and check whether your hospital participates in public banking if that’s your preference.
- Weeks 28 to 32: Enroll, complete paperwork, and pay your initial fee if going private.
- Weeks 32 to 36: Receive your collection kit and bring it to the hospital when you go into labor. Confirm with your OB or midwife that the delivery team knows you’re banking.
How Long Stored Samples Last
Cord blood stored in liquid nitrogen remains viable for decades. A 2024 study from the José Carreras Cord Blood Bank tested samples that had been frozen for up to 29 years and found cell viability averaging around 85 to 89 percent across all storage methods. That’s high enough for therapeutic use. While no samples have been tested beyond 29 years yet, the stability data suggests that properly stored cord blood could last even longer, making this a genuinely long-term investment.
Who Can and Can’t Donate
Most healthy pregnancies qualify for cord blood collection. Public banks have stricter screening requirements because the samples will be used in unrelated patients, so they apply the same kind of infectious disease testing and health history review used for blood donation. Certain maternal infections, a family history of specific genetic conditions, or complications during delivery may disqualify a public donation.
Private banks are generally more flexible since the sample stays within your family. However, the collected sample still undergoes testing, and factors like insufficient blood volume (common in premature births or after extended delayed clamping) can make a sample non-viable regardless of which type of bank you choose. Multiple births sometimes yield lower volumes per baby as well. Your bank and healthcare provider can help you understand whether your specific situation presents any obstacles.
