Pretransplant donor-specific antibodies detected by single-antigen bead flow cytometry are associated with inferior kidney transplant outcomes.

Background.The clinical significance of pretransplant donor-specific antibodies (pre-Tx DSAs) detected by single-antigen bead flow cytometry (SAB-FC) remains unclear.Methods.To investigate the impact that pre-Tx DSAs detected by SAB-FC have on early clinical outcomes, we tested pre-Tx sera from all
