Flow cytometry crossmatching for kidney transplantation

1. Overall, positive FCXM reactions were associated with graft losses in regrafts but not in primary transplants. 2. In transplants involving older female or CVA donors, a positive FCXM appeared to be deleterious in both first transplants and regrafts. If the donor were a younger male and not a CVA victim, only FCXM positive regrafts had low graft survival rates. 3. We presented a 3-color technique allowing the differentiation of antibody reactions against T cells, B cells, and monocytes. Another method allows the simultaneous evaluation of both IgG and IgM reactions against T cells. Using these kinds of methods may make better identification of antibodies that may be harmful to a transplant allograft possible.
