A. It is mediated by preformed cytotoxic antibody.

DISCUSSION: Hyperacute rejection is mediated by preformed cytotoxic antibody. It can be screened for by crossmatching procedures. It usually occurs immediately after graft placement or within the first 24 to 48 hours after graft placement. It is almost never reversible.
