An introduction to my journey

Let’s face it: every first-time mother buys too many supplies, over-priced baby clothes, and a whole slew of things that aren’t needed. The problem is, you often don’t find out how unnecessary it all was until much later when the receipts are gone and refunds are impossible. That’s how I felt about private cord blood banking until recently.

Three years ago when I was pregnant with my first child, I was bombarded with cord blood advertising at every turn: on the web, in magazines, and at my medical providers’ offices. Noting that my hospital, OB/GYN, and midwife all lined their walls with cord blood banking posters, I got the impression that it was indispensable. I decided to research the issue for myself so I could make an informed decision and counsel the pregnant women who assume that older means wiser (ha!) and gravitate towards me for advice.

After some digging, I discovered that there was another option to banking cord blood with the companies advertising in the doctor’s office: public cord blood banking. Public cord blood banking is similar to donating blood – by pooling the contributions of tens of thousands of donors, a valuable resource is created for society as a whole.

I was left wondering why my medical providers did not disclose the option to donate my son’s cord blood to a public bank. I discovered that a multitude of medical societies including the American Society for Blood and Marrow Transplantation, American Congress of Obstetricians and Gynecologists, the American Medical Association, and the American Academy of Pediatrics caution against private cord blood banking. They recommend that medical providers discuss all available options, disclose potential conflicts of interest, and steer patients towards public banking. Many of these associations’ opinions share in common the observation that expectant families are emotionally vulnerable and susceptible to misleading advertising about the usefulness of cord blood banking; for instance, when they claim that cord blood can be used to treat over 80 diseases, private cord blood companies fail to clearly state the caveat that 99% of the time it can’t be used to treat your own child. I didn’t understand why my medical providers promoted a service that their professional organizations did not support, and I hoped that they weren’t being swayed by financial incentives. I became convinced that private cord blood banking was a bad deal, one of the aforementioned things you buy and never need.

The plot twists and thickens

When a friend of mine whom I have always admired as a model of integrity and my go-to gal for everything pregnancy-related (she is a well-educated and recognized birth advocate) recently agreed to partner with a private cord blood bank, I was mortified. I felt that she had sold out, and I became newly determined to uncover the seedy underbelly of the private cord blood industry.

The information I wanted to find wasn’t readily available, so I reached out to thought leaders in the field including Dr. Frances Verter (founder of the Parent’s Guide to Cord Blood Foundation,, National Marrow Donor Program (NMDP,, and Cord Blood Registry (CBR, Slowly, a picture emerged that was more complex than anything I had anticipated, forcing me to question and ultimately abandon many of my previous beliefs about cord blood banking.

Insurance vs. Investment

Banking cord blood privately is often presented as a form of insurance. I don’t think this is a solid analogy. Insurance is supposed to protect you from a future risk by providing you with a known benefit. For example, car insurance will pay for auto repairs if you get into an accident, and home insurance will replace your house if it gets destroyed. With private banking, you don’t know which diseases will be treatable in the future with autologous cord blood. Today, autologous cord blood is not used as the standard treatment for hardly any diseases, and privately banked cord blood has merely a 1 in 4 chance of matching a natural-born non-identical sibling.

Rather, private cord blood banking is an investment because its future value is uncertain. Family banking is a medical investment that can turn out to be life saving, or it can be a money pit. As with all financial investments, you have to carefully consider your financial situation, risks, and expectations before making your decision. But unlike financial investments, this is infinitely more difficult to think about rationally because you’re dealing with something priceless – your child’s health.

Like any investment, you can only do so much with the money and information you have available when you make your decision. The responsible thing to do as a parent is to carefully think about your finances, disease risks, and how you’ll feel about your choice in the future under different contingencies. The most reputable, objective, and well-presented source of information about cord blood on the Internet is, but it still doesn’t have all the answers, nor can it tell you what’s right for you. While public banking makes sense for a great number of people, there are also legitimate reasons and circumstances for private banking. And, in a situation like mine when you’re pregnant with twins so you’re not eligible to bank publicly but can’t afford to bank privately, it’s also OK to choose “none of the above.”

Can’t we all just get along?

I was really heartened to hear every expert I spoke to talk about how we should put the differences of public versus private cord blood banking behind us. The only enemy here is the trash bin. Cord blood is a valuable resource, and we should be encouraging everyone to either donate it to a public bank or store it in a family bank whenever possible. 95% of cord blood is being thrown away, which means we have a long way to go. We need widely available literature that is free from bias, disclosures of conflicts of interest when medical providers receive actual or in-kind compensation from private banks, and training for clinicians to discuss this sensitive topic with expectant parents.

  1. I’m interested to know where Vivian was able to find a donation center near here. From my research, and in working with Be the Match, there are no centers or mail in options in CT. I have a friend who is banking their first’s cord blood, and we considered it for about a half second before we saw the cost! It really is frustrating to me that more people are not aware and fighting for more access to public cord blood donation, though I guess it has taken a celebrity like Robin Roberts to raise the needed awareness for bone marrow donation, maybe we need a celebrity to pick up the cord blood cause!

    1. Hi, Dena – I don’t think any CT hospitals do collections directly or partner with any facilities for donations. We did a mail in program with Carolinas (closest facility that accepts mail-in donations that doesn’t use if primarily for medical research). It requires pregistration, some testing, and your doctor has to agree to do the collection. I was just going to link a link to a website, but Cara linked the same website (

      We delivered at Stamford, but from what I was told, they didn’t partner with any public bank at the time.

      Interestingly, following on Cara’s note, we delivered late on a Friday (8pm). I was never told it was discarded or no longer viable??

  2. Another consideration is letting the cord blood flow back to the baby as it can hold a large percentage of the baby’s own blood. While it is true the baby might benefit from the cord blood in the future, we know they can benefit from it now. I personally just can’t in good faith take away any percentage of a newly born baby’s blood simply for the rare possibility he may have use for it in the future.

  3. Ok, here’s my question: BOTH pregnancies I wanted to donate my cord blood for scientific research. First time, I didn’t mention it to my dr. until I was too late in the pregnancy (I think they said I have to decide before 28 weeks, and no one had mentioned it until I did, so I had no clue about this rule). Second time, I said I wanted to donate it, and they gave me a pamphlet which told me I’d have to schedule a pick up by courier within 2 hours of the birth. I couldn’t do it ahead and they wouldn’t do it for me. So, I did all the paperwork intending to donate by courier, had the baby quickly with a lot of tearing, and never remembered to have a courier come for it, so it was discarded. What the heck? Is there an easier option? I was really frustrated.

  4. I am so glad that you posted this. When I was pregnant with my twins, I did a LOT of research on this because everyone told me exactly what you said – that it’s an “insurance policy” – but I didn’t believe it. What I found out was anecdotally what you provided facts for – that in many cases, you can’t use your own cord blood because the diseases that it’s intended to treat are often genetic (which means that it would be present in the cord blood already). Add to that the complexity of twins, and this becomes less of a viable option. Also, while it’s possible to use it on a sibling or family member, it needs to be a perfect match in order to be usable. For this reason, we chose to donate in hopes that if we ever need it, the favor will be matched by a different generous donor.

    Best of luck to you on your upcoming arrivals!!!

  5. I remember seeing all those posters and flyers in the doctor’s office but didn’t take the time to research. We didn’t do it. Thanks for sharing all this info, Cara, and for doing all the legwork for us! So informative!

  6. Oh, one more thing … I should know this, but I honestly don’t. If you wait to cut the cord until after it stops pulsing, on the premise that you are waiting to get as much of the iron-rich blood into the newborn as possible, does that mean that you cannot bank? So in other words, if you want to store/donate the blood but would also like to do delayed clamping, it can only be one or the other? I remember considering that during both my pregnancies, but I’m not sure if it really makes a difference or not.

    1. Delayed clamping will be the next article I tackle. 🙂 It is a complex issue and there is no consensus on how long the cord should continue pulsating. 5 minutes? 30 minutes? Some say 2 hours! It is more relevant with preemies (so some say) and there is research being done to do more with less. So one day delayed clamping and a possible very small collection could both be done. Once again, there is much room for improvement and clear, concise information n eeds to be more readily available.

  7. Yes! This is one of those subjects that I always have in the back of my mind, but it rarely comes up because not a lot of people talk about it. I wish more parents would take the time to do the research before falling prey to the advertising by these private cord blood banking businesses, scaring them into shelling out the money for something they will almost certainly never use. I will never forget the postcard I got in the mail when I was pregnant, featuring a mother standing in between her baby and a lion, with the caption “you would do anything to protect your baby” or words to that effect. Ugh! It’s downright unethical.
