crossmatching

crossmatching

 [kros´mach´ing]
a procedure vital in blood transfusions and organ transplantation. The recipient's erythrocytes or leukocytes are incubated with the donor's serum and vice versa. Various testing procedures are then performed to ensure that the donor and recipient have blood group compatibility or histocompatibility. Also written cross matching and cross-matching.

crossmatching

/cross·match·ing/ (-mach-ing) determination of the compatibility of the blood of a donor and that of a recipient before transfusion by placing the donor's cells in the recipient's serum and the recipient's cells in the donor's serum; absence of agglutination, hemolysis, and cytotoxicity indicates compatibility.

crossmatching

Etymology: L, crux + AS, gemaecca, matching
a procedure in blood transfusions and organ transplantation. The recipient's erythrocytes or leukocytes are incubated with the donor's serum and vice versa. Various testing procedures are then performed to ensure that the donor and recipient have blood group compatibility or histocompatibility. Compare blood typing. See also ABO blood group, Rh factor, transfusion, transfusion reaction.

crossmatching

1. The process of mixing a sample of the donor's red blood cells with the recipient's serum (major crossmatching) and mixing a sample of the recipient's blood with the donor's serum (minor crossmatching). It is done before transfusion to determine compatibility of blood.
2. The determination of the compatibility of a donated organ's human leukocyte antigens with the recipient's antigens.
