Comparative platelet activation profile between pooled granulocyte concentrates ( PGC ) versus apheresis ( APC ) and buffy coat ( BC ‐ PC ) method

Key Points

• This research compares the platelet activation profiles of different granulocyte concentrate methods to assess transfusion safety and optimization.
• Compared platelet activation in pooled granulocyte concentrates (PGC), apheresis (APC), and buffy coat (BC-PC) methods.
• Analyzed the yield and activation status of platelets derived from each method.
• Evaluated immune interaction potential of activated platelets.
• PGC shows higher granulocyte yield compared to APC and BC-PC methods.
• Activated platelet populations were significantly different across the methods.
• Optimization is necessary to enhance safety and standardize transfusions.
