to determine the compatibility of antibodies of donor and recipient

Explanation: "Tissue typing" primarily means HLA (histocompatibility) typing and cross‑matching. It checks donor HLA antigens against the recipient and looks for preformed anti‑donor antibodies in the recipient (which would cause hyperacute rejection). ABO (blood) typing is done separately; tissue typing is about histocompatibility/antibody compatibility.
