ABO blood grouping and Rh typing
Scientists have discovered more than 40 different types of blood in the human body. However, some of them are prevalent to most people, so we’ll focus on them. For example, the 4 main types of blood are A, B, AB, and O.
This type of grouping or blood system is created based on the antigens present on the surface of red blood cells. People who have type A blood have the A antigen; people who have type B blood have the B antigen. Similarly, people who have type AB blood have both A and B antigens, and finally, people with type O blood have no antigens at all.
The Rh typing also comes into play here. Blood types can have 2 Rh options – positive or negative. Rh-positive blood has a specific antibody present on the red blood cells. Rh-negative blood doesn’t have this antibody.
Delivering the wrong type of blood to a person can pose serious complications. There is a risk of blood clumping and agglutination. These conditions can be life-threatening as they tend to damage most of the tissues and organs in the body of the recipient.
