What is the difference between ABO and Rh blood group?

What is the difference between ABO and Rh blood group?

One difference between the Rhesus system and the ABO group system is that Rh negative people don’t usually possess antibodies against RhD (unless they have been previously exposed to it), whereas in the ABO group system if the antigen is absent from the red blood cell, the antibody against it is present in the plasma.

What is the human ABO blood group system What is the Rh system?

ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood.

What are blood groups discuss ABO and Rh grouping?

Blood type tests categorize your blood according to the major human blood group (ABO) system. A person’s ABO type depends upon the presence or absence of two genes — the A and B genes. The Rh test determines whether this configuration is present (“Rh-positive”) or absent (“Rh-negative”) on an individual’s blood cells.

What are the two blood grouping systems?

There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.

What is the principle of blood grouping?

Principle: The ABO and Rh blood grouping system is based on agglutination reaction. When red blood cells carrying one or both the antigens are exposed to the corresponding antibodies they interact with each other to form visible agglutination or clumping.

What are the methods of blood grouping?
