Cross-matching tests in transfusion medicine primarily assess what?

Cross-matching tests are about ensuring compatibility between donor and recipient blood to prevent immune reactions during transfusion. By mixing the recipient’s serum with the donor’s red blood cells (major crossmatch), and sometimes the donor’s serum with the recipient’s red blood cells (minor crossmatch), we look for antibodies that would attack donor cells. If no harmful reactions occur in this test, the transfusion is considered compatible. The other options don’t address compatibility: color or red cell count don’t measure immune readiness, and antibodies against donor HLA in the recipient are more relevant to organ transplantation than routine transfusion crossmatching.
