P129 Dealing with false-positive virtual crossmatch in lung recipients

Virtual crossmatch (VXM) has increased non-local organ utilization and improved clinical outcomes for sensitized lung patients. However, the concordance between VXM and cell-based crossmatch is not absolute because Single Antigen Bead (SAB) assay is prone to both false-negative and false-positive reactions. Since false-positive antibody specificities may unnecessarily deny an organ based on VXM, the goal of this study was to evaluate what...
