TimeCritical® Processing

Time is the one factor having the greatest impact on the number of viable stem cells that can be saved for your family. Studies show that processing of cord blood stem cells should optimally be undertaken within 12 hours of collection (TimeCritical Processing).1

The primary reason for banking your baby's cord blood and cord tissue stem cells is to ensure the best chance of survival if you or a family member is ever faced with a critical disease or condition.

Having more viable stem cells available at the time of a transplant directly correlates to transplant success and patient survival rate.2

Processing cord blood within 12 hours after collection yields a significantly greater number of viable stem cells, and colony forming units that grow into life-saving tissue.

Time impacts stem cell viability


Stem Cell Recovery Chart - 12 hours verses 24 hours

Most cord blood banks report an average time from collection to processing of 24 hours or more.

Specimens processed 24 hours or more after collection results in a significant loss of both mononucleated cells (MNCs) and stem cell colony forming units (CFUs), compared to those processed within the first 12 hours after cord blood collection.

MiracleCord has the unique ability to process umbilical cord blood and cord tissue specimens within 12 hours after collection.3
