ABO Rh test

This is a simple blood test which is used to find out the blood group and Rh type of a person. All human beings have about 4-6 litres of blood. Blood comprises two components –cells and plasma. The main cells present in blood are red blood cells, white blood cells and platelets. Plasma is the fluid in which these cells are present.

There are different types of proteins present in blood known as antigens and antibodies. Antigens are present on the surface of red blood cells and antibodies are present in plasma .These antigens and antibodies determine the blood group and Rh type of a person. There are 8 different blood types according to different combinations of antigen and antibodies-A positive,A negative,B positive,B negative,AB positive,AB negative,O positive and O negative. These blood group types are determined genetically.

O negative blood type is also called universal donor. AB positive blood type is also called universal recipient.
