[Analysis of Residual Leukocytes and Lymphocytes in Blood Cell Separator Based on LRS Technology and Research on Measures to Reduce Lymphocyte Loss of Blood Donors].

When collecting platelets using an LRS-based blood cell separator, if no plasma is reinfused or 30 ml plasma is reinfused, a certain amount of peripheral blood leukocytes, especially lymphocytes of blood donors, will remain in the LRS chamber, which may lead to peripheral blood lymphocyte loss in donors who undergo longterm and frequent apheresis platelet donation. In order to ensure the health of blood donors, emphasis should be placed on adopting effective plasma reinfusion protocols to minimize the loss of peripheral lymphocytes after blood donation.
