Compatibility testing for agglutination of donor RBCs by the recipients' serum is called ________.

Question

Quizplus · Accepted Answer

Cross matching is the process of testing the compatibility of donor red blood cells (RBCs) with the recipient's serum. This is done by mixing a sample of the recipient's serum with a sample of the donor's RBCs and checking for agglutination (clumping). This is done before a blood transfusion to prevent transfusion reactions. Blood typing is the initial step in blood compatibility testing, but it only identifies the type of antigens present on the RBCs. Transfusion reaction refers to the negative effects that can occur if incompatible blood is transfused. Hemolysis refers to the destruction of RBCs. Hemodialysis is a medical procedure that is used to filter blood in cases of kidney failure.
