Exploring the influence of donor physiognomic factors on packed red cell unit quality: A retrospective analysis from a tertiary care transfusion center

Donor PHB significantly influences the quality of PRBCs prepared, with lower PHB levels correlating with decreased UTHB. PRBCs prepared using the buffy coat method showed inferior UTHB, and older PRBC units displayed higher red cell hemolysis. However, donor gender, age, and weight did not significantly affect PRBC quality in this study. Larger sample sizes are necessary to confirm these findings. These results highlight the importance of donor screening and selection to optimize PRBC quality and enhance transfusion therapy outcomes.
