The percentage yield of TNC indicates the processing quality for each sample and the yield of the number of TNC per milliliter represents the processing quality of a cord blood bank. Therefore, the accuracy of percentage yield must be supported by the yield per milliliter. At Progenics, the average yield (%) and the yield per milliliter on all cord blood units that are banked at our facility. This distinguishes Progenics’ results from claims made by most other cord blood 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 milliliter from processing.
