Highest Yield of Total Nucleated Cells (%)
At Progenics, the average yield of TNC is 98% and the average yield of TNC per millilitre (mL) of cord blood is 14.6 x 106 cells/mL (20% higher than other results that have been published in scientific journals).
What is Yield of TNC?
The percentage yield of TNC indicates the processing quality for each sample and the yield of TNC per mL represents the processing quality of a cord blood bank. Therefore, the accuracy of percentage yield must be supported by the yield per mL. At Progenics, the average yield (%) and the yield per mL are based on all cord blood units that are banked at our facility. This distinguishes Progenics’ results from claims that are made by most other banks. In addition, our quality has been published in a peer-reviewed journal (Yang H et al, Transfusion (2011) 51;284-292).
This formula can be applied to indicate processing quality regardless of processing methods! Simply put, higher yield equals higher quality. However, it should also be supported by the yield of cells per mL from processing.
Highest Processing Success Rate
Cord blood can ONLY be processed once. Hence, the final product cannot be altered or improved any further once processing is complete. Under Progenics’ processing quality standard, close to 50% cord blood samples processed by other cord blood banks could not meet the Progenics’ criterion, since the average yield for most cord blood banks is only around 80%. In contrast, at Progenics, only ~1 in every 1,000 cord blood samples has a yield of TNC lower than 85%.
Higher Viability of Cells
Unique Processing Quality Certificate
Cord Blood Collection Bag with a Sterile Interior & Exterior
We use Pall cord blood collection bags which have completed an extensive sterilization process (internally and externally). This is critical for collecting cord blood safely, especially for C-sections. The bag is FDA NDA approved and CE marked under the Medical Devices Directive for the collection of cord blood.
At Progenics, we use Pall freezing bags which have two compartments. The cord blood stem cells can either be used for up to two transplants, or one compartment can be used for expansion, and the other for a direct transplant. Taking into consideration all of the quality indicators, Progenics’ quality is superior to all other banks worldwide based on available information that has been published in scientific and medical journals.
Highest Standard For Success of Processing
At Progenics, the success of processing is defined by a yield of Total Nucleated Cells that is ≥ 85%. To our knowledge, this is the highest guaranteed standard for quality in the cord blood banking field.
