Flow cytometry crossmatch

WebAbstract. In renal transplantation, the presence of anti-donor HLA antibodies is associated with early rejection and accelerated graft loss. The clinical relevance of anti-HLA antibodies can be evaluated in the crossmatch assay using either a complement-dependent cytotoxicity (CDC) assay or a flow cytometric crossmatch (FCXM) method. The FCXM ... WebFlowDSA-XM advances the science of crossmatch testing by combining traditional flow cytometry with microbead technology. Together, these proven technologies selectively …
