Blood groups and significance of blood grouping

Blood groups and significance of blood grouping :- The membrane of the red cell contains a number of blood group antigens called agglitinogen and the individual are divided inti 4 major types A, B, AB, and O. on the basis of agglutination present in the red blood cells.

The two main types of blood grouping system are ABO and RH.

ABO Grouping

Blood group are named after the antigen present in the red blood cells in each case of Plasma contain antibody to antigen not present in the blood.

The based on the present or absence of antigen A and antigen B, blood is divided into four groups A, B, AB or O group. Blood having antigen “A” belong to “A” group. This blood has anti-B agglutinin, a type “B” blood has anti-A  agglutinin, and types O both agglutinin and type AB neither in the plasma.

 

RH Grouping

The RH factor is so named because it was first found in the rhesus monkey it is a system consisting of about 12 antigen of these D is the most common antigen. The term RH positive refer to the presence of antigen D in the blood. The RH negative when injected with RH positive cell. Anti-D agglutinin does not naturally occur in the plasma.

Significance of blood grouping

The study of blood group (ABO) is significant with respect to the following



Blood Transfusion

In case of hemorrhage, burns, injuries, blood poisoning, the blood of one person can be intravenously transferred into the body of another person. This process is called blood transfusion. The person whose blood is given is known as Donor while the one who received is called as recipients.

A transfusion can be given from a Donor to a recipient of the some blood types without any complication because there will be no antibodies present in the plasma of the recipient which could cause agglutination of the cell being transfused.
