The blood will agglutinate if the antigens in the patient's blood match the antibodies in the test tube. A antibodies attach to A antigens - they match like a lock and key - and thus form a clump of red blood cells. In the same way B antibodies attach to B antigens and Rh antibodies to Rh antigens.
