What is Blood Groups?

The blood groups, also known as blood types, may be defined as the division of blood. They are determined by the existence or absence of genetically-derived antigenic substances found on the red blood cell’s surface (RBCs). The antigenic substances could be glycolipids, carbohydrates, glycoproteins or glycoproteins, based according to the type of blood system.

Karl Landsteiner, an Austrian scientist, discovered an Austrian scientist who discovered the ABO blood-group system around 1900. For his discovery, He was presented with the Nobel Prize.

A blood group or blood type is a blood classification, categorized based on the presence and absence of antibodies and genetically derived antigenic particles on the surface of RBCs. There are four main blood groups in the human blood, including O A, B and AB and is known as ABO, which is also known as the ABO blood group. There are certain methods by which blood types should be matched to ensure a safe transfusion.

  • Blood Group A- Antigen A within the RBCs and antibody B in plasma.
  • Blood group B-Presences of antigen B in the RBCs and A antibodies in plasma.
  • Blood group AB-Presences of both antigen A and B in red blood cells, but not the antibody.
  • Blood group O-Absence of both antigens A and B on red blood cells and the presence of both antibodies B and A in plasma.

Blood Types

O-, O+

Patients of any blood type can receive O positive blood. Type O blood is needed and should be in stock for newborns and patients in need of emergency. O+ is considered the more commonly occurring blood type that can be found in nearly 37 per cent of people. Ois found in 6 per cent of the population.


It is the second most commonly occurring blood kind. About 34% of people are A+.

A-, B+, B-

They are sporadic blood types, and less than 10% of people have the blood type.


This blood type is considered as”the “universal recipient” since AB+ individuals can take red blood cells of any other blood kind. Within the United States, less than 4 per cent have this kind of blood.


It is the least popular blood kind in America because less than 1 per cent of people within the United States have AB negative blood. Patients with AB negative blood may receive the red blood cell from any harmful blood types.
