What is the purpose of preoperative crossmatching for blood products?

Explanation:
Crossmatching is done to ensure that donor blood is compatible with the patient before surgery. It tests donor red cells against the patient’s serum (or uses an electronic method) to detect antibodies that could cause a transfusion reaction and to confirm compatibility beyond just knowing the ABO type. The key practical goal is to guarantee that there is a unit available that is compatible with the patient if transfusion becomes necessary. It’s not about assessing coagulation or screening for anemia; those are separate preoperative tests.
