<h3>What is blood typing?</h3>
Blood typing refers to the process by which blood is classified into types.
The process of typing blood involves reactions in which agglutination of blood occurs when a certain type of antiserum is dropped into the blood that contains a particular antigen such that an antibody-antigen pair is obtained.
The presence of certain antigens on the surface of blood helps to classify blood into types.
For example, when anti-A serum is added to a blood sample and agglutination occurs, the blood type could be either blood type A or blood type AB as these blood samples contain the A antigen on the surface of the red blood cells.
Similarly, when anti-D serum is added to a blood sample, the blood type is a blood group D as this blood sample contains the D antigen on the surface of the red blood cells.
