Crossmatching

Crossmatching is a medical testing procedure used primarily before blood transfusions or organ transplants. It involves mixing a sample of a donor's blood or tissue with a recipient's blood or tissue to determine compatibility. This helps ensure that the recipient’s immune system will not reject the transfused blood or transplanted organ. If the samples mix without reacting negatively, it indicates a good match, reducing the risk of serious complications. Overall, crossmatching is a crucial step in making sure that blood and organs are safely transferred between individuals.
