5 things to know before banking your newborn’s cord blood      

Most people wouldn’t dream of driving a car or buying a house without buying an insurance plan — you simply never know what will happen. That’s the attraction of banking your newborn’s umbilical cord blood, too.

The blood in a baby’s umbilical cord contains blood stem cells, which can grow up to be almost any kind of blood or immune cell they’re coaxed to be.

These stem cells can treat conditions such as leukemia, anemia, sickle cell disease, and other rare diseases.

Most mamas have seen brochures in their doctor’s or midwife’s office about the value of storing baby’s precious cache of stem cells. If your child or a sibling develops a rare disease or some other condition with few treatment options, cord blood in the freezer may come to the rescue.

But just how useful those cells might be for one of your children is hard to predict and cord blood banking companies often overstate the possibilities. It’s true that thousands of stem cell transplants have treated blood, immune, and metabolic diseases since the late 1980s, but they’re also far from wonder-cells.

Before you commit, here are the 5 things you need to know about blood cord banking and your baby’s stem cells—

1. What do these cells do that others can’t?

Until the discovery of cord blood stem cells, the only transplants that could treat conditions such as leukemia were bone marrow transplants, which carry a higher risk of blood-borne infections or the body’s immune system rejecting the transplant.

Stem cells offer a less risky alternative, but only for children. There aren’t enough cells in cord blood for an adult, and there are only enough for one transplant.

The process of stem cells “growing up” also takes longer after one of these transplants, which means the window for other infections is longer too.

2. So if my child has leukemia, their stem cells might help them?

Not necessarily. If your child’s immune cells couldn’t fight the leukemia already, more of the same is unlikely to help. Similarly, stem cells can’t help much if your child has a genetic disorder because their stem cells have the same genes.

Stem cells are more likely to help siblings, but that’s only if the blood matches — a 25% chance.

3. What other conditions can stem cell transplants treat?

Currently, stem cells can successfully treat five types of conditions in people: blood cancers, bone marrow failure, genetic blood disorders, immunodeficiencies, and genetic metabolic disorders. (Here’s a complete list of the conditions, most of which are fairly rare.)

It’s hard to estimate both the likelihood of these diseases afflicting your child or a family member and the likelihood that cord blood can help them, but estimates range from 1 in 1,000 to 1 in 200,000. The most accepted number is about 1 in 2,700.

Clinical trials are testing how helpful cord blood might be for all sorts of conditions, from diabetes to cerebral palsy to neurological and autoimmune disorders. But most of these willn ever pan out, and “promising results” on treating deafness, arthritis, Parkinson’s, and liver cirrhosis refer to studies in rats rather than humans.

4. So is there any point to banking?

Sure. If you know of a family medical history involving a condition that’s treatable with stem cell transplants, banked cord blood could be a lifesaver later on for a sibling or other family member.

The heartwarming success stories companies describe are real and people have definitely benefited from banked cord blood. Plus, technological advances may discover other remarkable uses for cord blood.

It’s just that the odds are pretty low that you’ll need them and other treatments may come along in the meantime.

Like most insurance policies, cord blood banking is a gamble—and not a cheap one. Banks charge between $2,000 and $4,500 to store the blood for up to 21 years, usually requiring a maintenance fee of $100 to$300 a year on top of that.

If you go with a commercial bank, research carefully how well the blood is stored and, if available, what FDA inspections have revealed about them.

5. Are there any alternatives?

Yes! If you decide commercial cord banking isn’t right for your family, you can also donate it to a public cord blood bank for research or others’ treatments. Donating is free!

Unfortunately, you may not be able to get it back if you need it later. However, if you know ahead of time that someone in the family may need it for a condition treatable with stem cells, you can make a “directed donation” that reserves it for that person’s use only (non-transferable and also offered by private banks).
