Quality Matters


Get the Most out of Your Cord Blood

The quantity and viability of stem cells extracted from cord blood units are critical parameters for a successful transplantation. Progenics consistently yields a high average of 98% of Total Nucleated Cells (TNCs) from all cord blood units processed between the year of 2014-2018 (Graph on the left).

What is Yield of TNC?

The percentage of total yield of  nucleated cells (TNC) indicates the processing quality of a cord blood bank. Please look at the formula on the right.

This formula is use to calculate the percentage of total  nucleated cells for all cord blood units that are banked at our facility. Simply put, a higher yield(%) equals higher quality. This distinguishes Progenics’ results from claims made by most other cord blood banks. We are proud of our consistent high yield of TNC which are shown in Annual Quality Reports. For further information, please have a look on our published peer-reviewed journal. (Yang H et al, Transfusion (2011) 51;284-292).


Higher Viability of Stem Cells

It has been supported that a shorter time between collection and processing is a critical factor that affects banking quality (Pope B., et al Transfusion 2012), this ensures that stem cells processed will have a higher viability. The sooner the processing method begins, the higher the quality of post processed cord blood.
At Progenics, the average period between the collection time of a cord blood unit and the start of cryopreservation is within 48 hours. If a cord blood unit is received after 48 hours from the time of collection, then the quality parameters will be assessed to determine whether the cord blood is still eligible for processing and storage.

Certificate of Cryopreservation

A Certificate of Cryopreservation that includes important quality indicators will be issued to the parents.It includes:

a)Client full name and Progenics ID number

b)Cord blood volume that was collected

c)The yield of TNC (%)

d)The number of total nucleated cells (TNC) banked for transplantation
