Lymphocyte Crossmatch

Lymphocyte crossmatch is a laboratory test used before an organ transplant to check if a recipient's immune system might attack the donor's cells. It involves mixing the recipient's blood with cells from the donor and looking for signs of immune reaction, such as cell destruction or antibody binding. A positive result indicates the recipient has antibodies against the donor's cells, increasing the risk of organ rejection. This test helps doctors determine compatibility and decide whether additional treatments are necessary for a successful transplant.
