These antibodies were originally discovered in the early 1900s and are now known to consist of immunoglobulin IgM, IgG, and IgA classes. The person who possessed the corresponding antigens was called Rh-positive. So the basic principle of blood donation is that there should be no antibody to match the RBCs surface antigen. The tube method is more accurate than the slide method. If all test is negative, then the fetus is not at risk. To create a coverslip smear preparation, a coverslip is picked up by the corner and the point is held between the thumb and forefinger in one hand. The mothers sensitization can be prevented by giving. The capillary pipette is put down and a second coverslip is placed . It is important for the blood cells to match while transfusing i.e. In the case of anemic patients, there may be fewer RBCs to be tested.
