End-stage hemolytic rate of leukocyte-reduced RBCs in additive solution: a 5-year retrospective study
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 11
Abstract
Objective To evaluate the suitability of current quality standard for end-stage hemolytic rate required by Quality Requirements for Whole Blood and Blood Components in Taiyuan through a 5- year retrospective analysis of leukocyte-reduced RBCs in additive solution in Taiyuan Blood Center. Methods A total of 240 packs of leukocyte-reduced RBCs in additive solution were collected from January 2007 to December 2021. Hb concentration, hematocrit(Hct) and free Hb in supernatant at end-stage were detected to measure the hemolytic rate. And the hemolytic rate was then compared with the current standard(0.8%) to analyze whether statistical differences existed. Results The hemolytic rate of leukocyte-reduced RBCs in additive solution were 0.109±0.123 in 2017, 0.113±0.085 in 2018, 0.121±0.076 in 2019, 0.101±0.057 in 2020, and 0.128±0.089 in 2021, with no significant difference among each other (P>0.05). And 97.5% of the products showed an end-stage hemolytic rate below 0.4%, 0.83% among 0.6%~0.7%, and none over the standard of 0.8%. Conclusion The current national standard for end-stage hemolytic rate of leukocyte-reduced RBCs in additive solution might not be suitable for blood quality control in Taiyuan, and a much stricter criteria should be considered.
