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 human blood consists of 4 main components, the red blood cells, the white blood cells, the plasma and the platelets.The red blood cells are the components that help in determining a persons blood type.The ABO system is the main blood grouping system behind the principle that helps classify people into one of the following four groups, i.e., There are 22 blood group systems, including the ABO, Rh, and Kell blood groups which contain antigens that can provoke the most severe transfusion reactions. When the mother is Rh-negative and the fetus Rh-positive, the mother may be sensitized at delivery due to feto-maternal blood mixing. Plasmodium species because of dehemoglobinized of RBCs in thick smear. Not all tests can be run on capillary samples. For live specimens, the water will allow the user to view its movement or motility and observe cell division. The action of the H gene substance ultimately gives rise to ABO antigens.
