crossmatch

Serologic crossmatch Transfusion medicine An agglutination test that determines donor-recipient blood compatibility. See Electronic crossmatch, Immediate spin crossmatch, Major crossmatch, Minor crossmatch.
Crossmatch
Major crossmatch Patient serum–which may contain antibodies is cross-reacted against the donor's red cells and
Minor crossmatch Patient RBCs are incubated with donor serum, this is of less clinical significance; it reveals donor antibodies against uncommon antigens–eg Cw, -Wra, -Lia 

Crossmatch

A laboratory test done to confirm that blood from a donor and blood from the recipient are compatible.
