Collecting cord blood at birth is a crucial role, ensuring that life-saving stem cells are safely stored for future use. We know that it’s so important for parents to understand the process behind what happens when they choose to collect and store their baby’s stem cells. So today we’re answering the most commonly asked questions about cord blood collection from a phlebotomist’s perspective.

  1. What Exactly is Cord Blood, and Why is it Collected?

Cord blood is the blood remaining in the umbilical cord and placenta after birth, rich in stem cells that can be used in treatments for over 80 medical conditions, including blood disorders, immune deficiencies, and certain cancers. Unlike bone marrow collection, it’s non-invasive and painless for both mother and baby.

  1. When is Cord Blood Collected?

Cord blood is collected immediately after birth, before the placenta is delivered. Timing is key – once the cord is clamped and cut, collection should happen as soon as possible to ensure the maximum number of viable stem cells.

  1. Who Can Collect Cord Blood?

Phlebotomists trained in cord blood collection can perform the procedure. In some hospitals, midwives or obstetricians may also be trained to collect cord blood.

  1. What Equipment is Needed for Collection?

At Smart Cells, we provide a collection kit.

The priority is ensuring that the cord blood collection process is smooth, safe, and effective. The essential equipment includes a sterile collection bag with an anticoagulant to preserve the sample, a needle for precise collection, and clamps to secure the cord before collection begins.

But collecting the sample is only half the story – how it’s transported is just as crucial. That’s why Smart Cells provides a specialised stem cell collection kit equipped with NanoCool technology. This innovative system keeps the sample at a stable, controlled temperature for up to 72 hours, ensuring its viability while in transit to the laboratory. Even if collection happens at an inconvenient time, there’s peace of mind knowing the sample will remain in perfect condition.

Once collected, the sample is securely packaged and handed over to Smart Cells’ trusted courier, who ensures it reaches their London laboratory swiftly and safely. With the right collection process and advanced transport solutions like NanoCool, families can be confident that their baby’s precious stem cells are preserved to the highest standard.

  1. How Much Blood Should Be Collected?

The aim is to collect at least 60ml of cord blood, but the more, the better! A sample smaller than 40ml may not contain enough stem cells for effective storage and future use.

  1. Is Cord Blood Collection Painful?

No, cord blood collection is completely painless for both mother and baby. The process takes place after the umbilical cord has been clamped and cut, meaning there are no nerve endings involved. Unlike other forms of blood collection, such as venipuncture, this procedure does not require any needles for the mother or baby, making it a safe and comfortable process.

  1. Can Cord Blood Be Collected During Delayed Cord Clamping?

Yes, but it can reduce the volume collected. Some parents choose to delay cord clamping for 1-2 minutes to allow extra blood to return to the baby. In these cases, collection may still be possible but with a lower yield.

  1. How Will the Sample Be Stored and Transported?

Once collected:

  • The sample should be kept at room temperature (not refrigerated or exposed to heat).
  • It must be delivered to the cord blood bank within 72 hours for processing.
  • Ensure all documentation is complete and attached to avoid delays.

Our couriers will ensure that your sample arrives as quickly as possible and safely.

  1. What Happens After Collection?

Once the sample reaches the cord blood bank:

  • It is tested for viability and contamination.
  • If suitable, it is processed and cryopreserved for long-term storage.
  • Parents are usually notified about the status of their sample within a few weeks.

If you ever have concerns about a collection, always refer to the guidelines provided by the cord blood bank you’re working with—precision and professionalism make all the difference!
