WebFeb 27, 1997 · Even if some authors have observed lower 1-year graft survival and higher incidence of rejection in transplant recipients with positive flow cytometry cross-match(FCXM *) before transplant, consensus about the importance and clinical relevance of FCXM has not yet been reached. WebApr 1, 2024 · virtual crossmatching. Before kidney transplantation, donor-recipient compatibility is assessed by physical crossmatching at most programs. This is done by either cytotoxic assays or, more commonly, flow cytometry. Physical crossmatching is costly, resource-intensive, and time-consuming.

The human leukocyte antigen (HLA) proteins are crucial for the body’s immune defense against potentially harmful foreign substances. Class I and II HLA (HLA I and II) proteins are the ones involved with the immune response and transplantations. HLA I proteins are expressed on the surface of all cells.
