RhoGAM, Rh Immunoglobulin Administration, is a product that contains antibodies to the Rh D antigen, it is used to prevent the mother from developing an immune response to fetal red blood cells. RhIg ‘coats’ any Rh-positive fetal red blood cells that enter the mother’s bloodstream, effectively ‘hiding’ them from the mother’s immune ...
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
Rh o (D) immune globulin (RhIG) is a medication used to prevent RhD isoimmunization in mothers who are RhD negative and to treat idiopathic thrombocytopenic purpura (ITP) in people who are Rh positive. [2] It is often given both during and following pregnancy. [2] It may also be used when RhD-negative people are given RhD-positive blood. [2]
The name rhesus factor (Rh) goes back to the use of erythrocytes extracted from the blood of rhesus monkeys for obtaining the first blood serum. The Rh blood group system is a human blood group system. It contains proteins on the surface of red blood cells. After the ABO blood group system, it is the most likely to be involved in transfusion ...
The entire Rh blood group system involves multiple antigens and genes. For Rh factor testing, however, only the Rhesus factor correlated to the RhD antigen is assayed. The RhD gene that codes for the RhD antigen is located on chromosome 1. This chromosome contains gene instructions for making proteins in the body. [3]

However, Wiener soon realized that the new blood factor they had discovered was associated with problems in blood transfusions. Although the first time Rh positive blood is transfused into someone with Rh negative blood, it may not cause any harm, it does cause the creation of antibodies which make a second such transfusion very dangerous.
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...
