Improvement of storage of blood products

Project leader: Margriet Dijkstra-Tiekstra PhD

Improving materials and methods

The department Transfusion Monitoring (TraM) of Sanquin Research in Groningen has organized the study BEST (Biomedical Excellence for Safer Transfusion) Collaborative to evaluate the effect of overnight storage of whole blood or buffy coats on in vitro quality of platelets concentrates. Included in this study were six centers located in Europe and Northern America.

Besides this, TraM also carries out research projects for the stem cell department. A study was performed to optimize freezing conditions of stem cells. The influence of sample materials on the in vitro quality of stem cell simulated products using the current freezing program was evaluated, as well as the addition of DMSO. Additionally, pilots were done to find a way to validate HPC aphaeresis.

For the production-department, TraM studied the influence of prolonged separation of whole blood on amount of hemolysis. Hemolysis is significantly higher for red cells after prolonged separation and all hemolytic concentrates derived from units with prolonged separation.

Quality Improvement

Every year, TraM organizes 'send arounds' to compare the results of different instruments used within the different departments of Sanquin Blood Bank. Samples are prepared centrally at TraM and distributed to the participants. Afterwards the results are collected and analyzed. Reports with conclusions are written and sent to the different departments.

In 2010 again five national send arounds were executed.
