Is Cord Blood Banking Worth It?

At some point during your pregnancy someone at your OB’s office or at the bus stop might ask you what you’re doing about cord blood banking. When someone first asked me this there were audible crickets in the background. Cord blood whaaaaa? That’s a thing?!

Cord blood banking is when blood from inside the umbilical cord is collected just after a baby is born and then stored. Cord blood contains blood-forming stem cells—which are a magical type of cell that can reproduce into bone, heart, muscle, or nerve cells. Because stem cells haven’t decided what type of cell they will be yet, they can be used to treat a bunch of serious illnesses that require stem cell transplants, such as some nasty types of cancer, like leukemia. These illnesses often require harsh treatment, such as chemotherapy, that kills diseased and healthy cells—so these sick people often need a blood cell transplant to get strong again. New stem cells can grow into red blood cells, white blood cells, or platelets, thereby making the sick person recoup some of those lost healthy cells and build up a stronger immune system. The research on the use of stem cells is rapid and new uses for these types of donations are still being discovered.

The actual collection of cord blood is totally painless. After your wee babe is born and the umbilical cord is clamped and cut, a special kit is used to drain the blood out of the cord. After collection the blood is rushed to a blood bank, given an ID number, and frozen for a future transplant.


In terms of what kind of bank to use there are two options – public and private.

If you’re interested in public banking then your OB or midwife should be able to tell you how it will work at your delivery. (If they don’t facilitate the donation themselves, they might have info on local companies that will come to your hospital/house and collect the cord blood.)  The upshot of public banking is that it’s completely free and you’re doing a really good deed for someone who is seriously sick. (That’s some good karma right there.) Donating to a public bank is a lot like donating during a blood drive—you won’t know when or if the donation is used. Your baby’s stem cells are tested and typed and then if someone needs a stem cell transplant the doctor can look up potential matches in a national registry or database. So the downside of public donation is that you may not be able to later retrieve the donation—it belongs to the masses.

There are a TON of private banks if you want to go that route. The deal with this type of banking is that your baby’s stem cells are being privately frozen and held just for your family’s use. So in the horrible event that one of your future kids needs a stem cell transplant, a sibling’s blood cells are right there, ready to use! And close family members are often the best match because doctors want blood cells that are a close match for transplants. For that reason, if you have someone in your family who is currently ill and in need of a stem cell transplant then private banking is a great option.

The downside is that private banking costs a lot of cabbage—usually a couple thousand dollars to initially bank the blood and then an annual storing fee on top of that. Ouch.

In recent years the American Academy of Pediatrics and The American Society for Blood and Marrow have advised families to publicly bank for several reasons.

First, private banking costs some serious mula so it’s just not a financial possibility for many families. Second, unless someone in your family is already ill, the chance that you or one of your relatives will need a stem cell transplant is very slim. Third, a lot of these private banks prey on the fears and insecurities of new parents, which is just kind of a dick move.

Overall, there doesn’t seem to be a big downside to donating cord blood. If you decide to go for it you should get the ball rolling in your second trimester so you have plenty of time to choose what kind of bank to use and make all the necessary arrangements.

But wait—what about delaying cord clamping

Delaying cord clamping means that, rather than clamping the umbilical cord right after birth, the cord is clamped and cut a full two or three minutes after birth. Research has shown that if left to pulse for those additional minutes, the umbilical cord can deliver an additional 20-40mL of blood from the placenta to the baby. This means the newborn may get some extra iron from those few extra minutes attached to the ol’ placenta, which may help reduce anemia.

So the relevant question here is—can you delay cord clamping but still have enough cord blood remaining to bank? There seem to be a LOT of contradicting opinions about this on the Interwebs so I decided to ask someone who actually works in a hospital where cord blood is collected. I will preface this part by saying that her answer was very complicated and she is smarter than I and I only understood about 25% of it, but here goes. She told me the two most important things on the recipient side of a cord blood donation are:

  1. volume of blood donated and
  2. number of stem cells in that blood.

There is a minimum volume of blood and stem cells required for a transplant to occur, and delaying clamping *could* impact whether or not the cord blood can be processed for donation. I know, still kind of a vague answer because so much depends on the recipient of the donation, which in most cases is unknown. Smaller patients (like kids) weigh less so they don’t need as much blood or as many stem cells for a donation to work. Adults could require blood from two cords. So basically, if you feel very strongly about both delaying clamping AND banking cord blood, your best bet is asking whatever company is doing your cord blood collection if they think delaying the cord clamping will screw up the banking process and see what they say. And then can you explain it to me? Because this shit makes my brain hurt.

  • There are now more than 80 disease and counting that have FDA approval for being treated with stem cells. Check out the list here

    While public banking might be free to donate, retrieving units can cost between $30,000 and $40,000. Because public banks demand large volumes for research, most of the donations are discarded.

  • For what it’s worth, I donated in Toronto through Victoria Angels. I would not have heard about It if not for a friend. My doc had not heard of it. It had to be arranged several weeks ahead of the birth. There was no charge to collect. And they were able to delay clamping – perhaps not quite as long as they would if no donation was being made, but I was reassured my baby would get the benefit of a delayed clamp. I’m so glad we were able to do this.

  • BRCA mutations run rampant on both sides of my family, so we’re definitely going to privately bank our miracle baby’s cord blood. I have a BRCA mutation, and she may also–this gives her an 88% chance of developing breast cancer in her lifetime, along with a few other cancers with greatly increased risk. With all the BRCA positive people in my life, the money is definitely worth it to me. If course, we hope we never end up using it, but I’d rather shell out that $$ than not have it there.

  • You can get stem cells from other sources than umbilical cord. And you don’t need any banks for these sources either. I don’t think it’s worth it forking out money for something that might not be needed.

  • We delivered at a well known hospital in NC, and it was no problem for us to delay cutting and donate publicly. From my vantage point, the donation coordinator patiently waited until the cord was cut and although she appeared to have to "milk" the cord for the donation – it was just another day another delivery/donation.

  • Some important info to add and consider…

    Public cord banking is free, BUT you still have to pay your doctor to collect the blood. Your insurance may cover it, but just be forewarned, you will be billed something for this.

    For private banking, know that the vast majority of uses for cord blood can NOT be used by the child. Most of the current uses for cord blood are for a matched donor (e.g. a sibling), and there are very few applications for the person using their own cord blood (cerebral palsy is the condition that has the most promise for using the affected person’s blood). Unless you have already know someone who has a disease who can use stem cell treatment, financially it just doesn’t seem worth it.

  • I asked if I could donate to a public bank and do delayed cord clamping and my facility said no, they couldn’t do it. They said there wouldn’t be enough volume left to do the donation.
