As you might expect, processing and storing cord blood cells is a very meticulous process. Biological specimens are as fragile as they are precious, so true expertise, combined with constant review and comparison of all technologies available are essential. To extract the maximal number of stem cells, in the safest and most sterile way possible, all cord blood is processed using the Advanced Suspension Method of processing, which employs state-of-the-art technology. Your baby’s cord blood will be tested for cell viability, total nucleated cell count (TNC), sterility, infectious disease markers, number of stem cells, and blood type.

Further, our FDA approved and regulated storage facility partners with Community Blood Services (CBS) for processing. CBS is an FDA registered, AABB & American Society of Histocompatibility and Immunogenetics (ASHI) accredited lab. CBS is a member of National Cord Blood Inventory (NCBI) and the National Marrow Donor Program (NMDP). Learn more about CBS, including its 70+ years of experience providing high quality blood and tissue services.

At every step, the highest standards and attention to detail will safeguard your child’s cord blood. Simply get started by enrolling online and the rest will be handled by our expert teams of customer service and laboratory staff, making cord blood storage and processing with Maze easy and worry-free. 

Getting Started

Getting started with Maze is easy. Simply enroll online and choose a plan that’s right for your family. Our Cord Blood Coordinators personally pack your kit containing everything your physician or midwife needs to collect your baby’s cord blood and cord tissue. Place your collection kit in your hospital bag and bring it with you to the hospital when it’s time. Learn More 

Collection of Cord Blood and Cord Tissue

Once your baby has been delivered, and the cord clamped, your physician or midwife will collect your baby’s cord blood from the placenta and umbilical cord segment still attached to it.

If you’re storing cord tissue, a 3-5 inch section of the cord is cut and placed in a sterile, protective storage cup provided in your Maze Cord Blood collection kit. Then, both the cord blood collection bag and cord tissue storage cup are placed back into the kit and returned to you. Learn More 

Information for Physicians

We know parents have many questions surrounding cord blood banking, and it’s not uncommon for Physicians to have questions as well. Learn more about our Physician’s Guide, what’s in our kit, and how the Pall Cord Blood collection bag works.


Within two hours of the kit being returned to you, call the number on the collection kit. This call will go straight to our medical courier who will confirm all of your information with you and dispatch someone to pick up the kit from your hospital room. Your kit is then rushed to our processing lab. Your baby’s stem cells are viable for up to 72 hours, so refrigeration or freezing is not necessary at this point. Learn More 


Your baby’s stem cells will be processed using our Advanced Suspension Method which results in an increased number of viable stem cells and a reduction in the amount of red blood cell contamination. You will then receive an Official Certificate of Results, providing a detailed description of the collection volume and viability. Learn More 

Freezing and Storage

Once your cord blood has been processed, we store the stem cells in tanks holding nitrogen vapor (gas) at the optimal long-term storage temperature of -175º C or colder. We use vapor nitrogen over liquid nitrogen due to vapor’s ability to remain at a consistent temperature throughout the tank. Learn More 

Retrieving Cord Blood

No matter where you are in the world, if you need your cord blood, we can send it to you. And rest assured, cord blood that is already frozen can travel around the world without any loss of viability. Learn More
