Each blood group is determined by the presence or absence of two antigens. These antigens, A and B, are carbohydrate structures located on the red blood cell. In addition to the A and B antigens, a protein, termed the Rh factor, is either absent or present on each <abbrev>RBC</abbrev>. If the Rh factor is present, it is (+) and if the Rh factor is absent, it is (−). Laboratory testing for the <abbrev>ABO</abbrev> blood group system is determined by evaluating the presence or absence of A and B antigens (forward typing) as well as the presence or absence of their corresponding antibodies (reverse typing). Testing for the Rh blood group system evaluates the presence or absence of the D antigen. These tests are utilized to type donor blood, select compatible units of blood and plasma, and evaluate fetal/maternal compatibility.Read More
