Landsteiner test

The Landsteiner test is a laboratory procedure used to determine blood compatibility between donor and recipient. It involves mixing small samples of blood with specific antibodies that target blood group antigens. If the blood clumps or agglutinates, it indicates the presence of the corresponding antigen. This helps identify blood types and ensure safe transfusions by matching donor blood that will not cause a harmful immune reaction in the recipient. This test is fundamental for preventing transfusion reactions and ensuring blood compatibility.
